In cells, genetic information is transferred from DNA to mRNA. Which of the following best describes how mRNA is used to produce proteins?
• Ribosomes move along the mRNA strand and connect amino acids according to the sequence of the mRNA.
© The mRNA is replicated, and then both strands are folded into a three-dimensional structure known as a protein.
© Enzymes break up the mRNA strand so that amino acids found floating freely in the cytoplasm can bind to the mRNA
bases.
© Amino acids on ribosomes attach to the mRNA strand and then digest the strand, leaving the amino acids free
assemble into proteins.
Answers
Ribosomes move along the mRNA strand and connect amino acids according to the sequence of the mRNA. The correct option is A.
Thus, in order to create proteins, ribosomes move along the mRNA strand and join amino acids in the proper order. The mRNA molecule joins to a ribosome during translation, and the ribosome reads the nucleotide sequence on the mRNA one codon at a time.
A molecule known as transfer RNA (tRNA) transports each codon's designated amino acid to the ribosome. The ribosome then joins the amino acids in the polypeptide chain according to the mRNA sequence, which will eventually fold into a protein. The newly created protein is then released after the ribosome reaches a stop codon, which happens to be the end of this process.
Thus, the ideal selection is option A.

4. The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell would be: which option is correct a) 1 mole of ATP b) 2 moles of ATP c) 3 moles of ATP d) 4 moles of ATP e) 6 moles of ATP
Answers
The ATP yield from 2 moles of mitochondrial NADH under aerobic conditions in a eukaryotic cell is approximately 4 moles of ATP.
During oxidative phosphorylation, each mole of NADH can generate around 2.5 to 3 moles of ATP. Therefore, for 2 moles of NADH, the total ATP production would be in the range of 4 to 6 moles of ATP. While the more precise estimate falls within the 4 to 6 moles range, the closest option provided is 4 moles of ATP. It is important to note that the exact ATP yield can vary depending on factors such as the efficiency of the electron transport chain and the specific conditions within the cell.Since there are 2 moles of mitochondrial NADH, the total ATP yield would be around 4 to 6 moles of ATP. However, the most accurate option among the given choices is 4 moles of ATP.

Describe three ways in which the liquid contained in the ureter differs from the liquid contained in the renal artery
Answers
Answer: The three ways are listed below
Explanation:
Composition, The renal artery carries deoxygenated blood to the kidney, while the ureter carries urine after it has been filtered by the kidney. Urine contains waste products filtered from the blood, while the blood in the renal artery still has all its components.
Origin: The liquid in the renal artery originated from the heart as deoxygenated blood, while the liquid in the ureter originated from the renal tubules in the kidney as urine. They have different origins and histories.
Functions: The blood in the renal artery is essential for oxygenating the kidney and removing waste, while the urine in the ureter serves to transport the waste products filtered by the kidney out of the body for excretion. They serve very different functions.
Some additional notes:
• Urine contains waste materials like urea, creatinine, uric acid, etc. removed from the blood. The renal artery blood does not contain these waste products.
• The urine in the ureter is no longer useful for transportation of oxygen and nutrients. That is the purpose of the blood in the renal artery.
• The blood in the renal artery becomes deoxygenated after passing through the kidney, while the urine in the ureter remains oxygenated after being filtered.
• Manipulating the flow in the renal artery or ureter impacts the kidney differently. Reducing renal artery flow would damage the kidney, while reducing ureter flow would cause urine buildup.
• Urine volume and composition changes as it moves through the renal tubules and collects in the renal pelvis before entering the ureter. Blood composition remains largely unchanged as it passes through the kidney in the renal arteries.

Answers
Answer:
This question lacks options, options are:
A) ADH
B) aldosterone
C) atrial natriuretic hormone
D) oxytocin
E) prolactin
The correct answer is B.
Women have a tendency to retain water during part of the menstrual cycle because estrogen mimics the action of aldosterone.
Explanation:
The female sex hormones produced by the ovary (estrogens and progesterone) are substances that, through the blood, will carry messages to all the organs of the female genital system (uterus, tubes and ovaries) to achieve their correct function. Aldosterone concentration normally increases at the time of ovulation and remains elevated during the luteal phase of the menstrual cycle. Women present during the premenstrual phase, compared to the luteal and follicular phases, an increase in body weight, due to an increase in fluid retention, this because the menstrual cycle modulates the renin-angiotensin-aldosterone system. High levels of estrogen and progesterone in the mid-luteal phase are associated with a greater increase in adrenal and renal hormones and retention of more volume.

which cell organelles composed of a series of channels throughout the cytoplasm that functions in thranport of molecules
Answers
The cell organelles composed of a series of channels throughout the cytoplasm that function in the transport of molecules are called the endoplasmic reticulum (ER).
The ER is an extensive network of membranous tubules and sacs that are interconnected, forming a complex structure within the cytoplasm of eukaryotic cells.There are two types of endoplasmic reticulum: the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER). The RER is characterized by the presence of ribosomes on its surface, giving it a rough appearance. These ribosomes are involved in protein synthesis, and as the newly synthesized proteins enter the lumen of the RER, they are transported through the ER channels.The SER, on the other hand, lacks ribosomes and appears smooth. It plays a role in various cellular processes, including lipid metabolism, detoxification of drugs and toxins, and the storage and release of calcium ions.Both the RER and SER are involved in the transport of molecules within the cell. They provide a large surface area for the synthesis, modification, and transport of proteins and lipids. The channels and membranes of the ER allow for the efficient movement of molecules, including proteins, lipids, and ions, throughout the cytoplasm and to other cellular compartments.
In summary, the endoplasmic reticulum is the cell organelle composed of a series of channels throughout the cytoplasm that facilitates the transport of molecules, enabling the efficient distribution of proteins, lipids, and other substances within the cell.

There are three sources of genetic variation in sexual reproduction. Determine which of the following statements accurately describes which of these are considered random and which are not
Answers
Genetic recombination and independent assortment are considered random sources of genetic variation, while mutations can occur randomly or due to specific factors.
In sexual reproduction, the three sources of genetic variation are genetic recombination, independent assortment, and random mutations. Among these sources, genetic recombination and independent assortment are considered random processes, while mutations are not entirely random.Genetic recombination occurs during meiosis when homologous chromosomes exchange genetic material through crossing over. This process is considered random as the precise locations where recombination events occur are unpredictable.Independent assortment refers to the random alignment and separation of homologous chromosomes during meiosis I. The random positioning of maternal and paternal chromosomes contributes to genetic diversity in offspring.On the other hand, mutations are not entirely random as they can be influenced by various factors such as exposure to mutagens or errors in DNA replication. However, the specific mutations that occur at particular loci are generally considered random events.Therefore, the accurate statement would be that genetic recombination and independent assortment are considered random sources of genetic variation, while mutations are influenced by both random and non-random factors.For more such questions on Genetic variation:

1. How does calcium ion concentration in blood affect muscle contraction? Does it lead to tetany in certain cases? How will you correlate fluctuation in blood calcium with tetany?
Answers
Calcium ion concentration in the blood affects muscle contraction because actin and myosin filaments return to their initial places as calcium ions leave the muscle cells, causing the muscle to relax.
The muscle relaxes as calcium ions leave the muscle cells, causing the actin and myosin filaments to return to their initial positions. In other words, a lower calcium level in muscles is indicated by a larger level of calcium ions in the blood. Muscle contraction will suffer as a result of this.
Muscle contraction results from the thin and thick filaments sliding apart from one another when Ca2+ is present in the cytosol. Similar to this, as the Ca2+ level drops, the binding sites are covered, causing contraction to cease.
Low calcium levels in bodily fluids due to impaired parathyroid gland function occur in cases of tetany. Periodic, excruciating muscle spasms (wild contractions) and trembling are symptoms of tetany.
