In mRNA (transcription) synthesis and DNA (replication) synthesis, there is the need for their production to move in the 5' to 3' direction. This is a fundamental rule in their synthesis.
The 5' to 3 direction is also regarded as the orientation/position of carbon atoms in the nucleotides in particular the 5th and the 3rd carbon atoms in either the mRNA sugar (ribose) or the DNA sugar backbone (deoxyribose).
The end of the strand with an unlinked 5' carbon is the 5' end while that of the end with the unlinked 3' carbon is the 3' end.

Answers
The net sugar source for a deciduous angiosperm tree is a) new leaves in early spring.
In deciduous angiosperm trees, new leaves in early spring are a net sugar source. During this time, the tree undergoes bud break, and new leaves emerge. These newly developed leaves contain chlorophyll and are actively involved in photosynthesis.
They capture sunlight and convert it into chemical energy in the form of sugars (such as glucose) through photosynthesis. These sugars are then transported to various parts of the tree, including storage tissues, developing fruits, and other growing tissues, to support growth and development.

What modern technology enables identification of proteins, peptides and other molecules due to its extreme, down to 1Da, accuracy. a. mass spectrometry b. qPCR c. UV spectroscopy d. NMR e. HPLC
Answers
Mass spectrometry is the modern technology that enables identification of proteins, peptides, and other molecules with extreme accuracy down to 1Da.
Mass spectrometry is a powerful analytical technique used in various fields, including chemistry, biochemistry, and proteomics, for the identification and characterization of molecules. It measures the mass-to-charge ratio (m/z) of ions to determine their identity and abundance. One of the key advantages of mass spectrometry is its high precision and accuracy in determining the mass of molecules.
Mass spectrometers can detect and distinguish molecules based on their mass-to-charge ratio with remarkable sensitivity. They can precisely measure the molecular weight of proteins, peptides, metabolites, and other molecules down to 1Da, which is an extremely small unit of mass. This level of accuracy allows researchers to identify and characterize specific molecules, analyze complex mixtures, and study biological processes at the molecular level.
Other technologies listed, such as qPCR (quantitative polymerase chain reaction), UV spectroscopy, NMR (nuclear magnetic resonance), and HPLC (high-performance liquid chromatography), are valuable techniques in their respective areas but do not offer the same level of accuracy and resolution as mass spectrometry for identifying and analyzing molecules at the atomic or molecular level. Mass spectrometry has revolutionized the field of proteomics and plays a crucial role in drug discovery, biomarker identification, and understanding disease mechanisms.

speaking of ancient animals, scientists named a recently discovered beaver fossil after which southern store chain?
Answers
The southern store chain in question is Buc-ee's, and the beaver fossil that was named after it is called Castoroides succulentus.
This fossil was discovered by a team of scientists in Florida, and they decided to name it after the convenience store chain because of its strong ties to the southern United States.
Buc-ee's is a popular convenience store chain that is known for its clean facilities, friendly staff, and wide range of food and beverage options. It is particularly popular in the southern United States, where it has a strong presence in states like Texas, Louisiana, and Alabama.
The discovery of Castoroides succulentus is an important one for scientists, as it provides new insights into the evolution of beavers and their role in ancient ecosystems. This giant beaver lived during the Pleistocene era, around 2.5 million to 10,000 years ago, and was one of the largest rodents to ever exist.
In conclusion, the recently discovered beaver fossil Castoroides succulentus was named after the southern store chain Buc-ee's because of the chain's strong ties to the southern United States. This discovery is significant for scientists because it provides new insights into the evolution of beavers and the history of the southeastern United States.

By 12 weeks, the uterus is just ____________ to the level of the ____________ and is about the size and shape of a large grapefruit. As the uterus expands, it impinges on the space occupied by the ____________ .
Answers
Answer: 1. superior 2. pubic symphysis 3. urinary bladder
Explanation:
Given our understanding of the human anatomy, we can confirm that by 12 weeks, the uterus is just superior to the level of the pubic symphysis and is about the size and shape of a large grapefruit. As the uterus expands, it impinges on the space occupied by the bladder.
As the question tells us once the spaces are filled in, the uterus, which holds the fetus during development, expands as the fetus grows in size. This expansion causes it to extend to the spaces superior to the pubic symphysis and the space occupied by the bladder.
The expansion of the uterus into the space occupied by the bladder causes this organ to have very limited space to expand, thus greatly limiting the amount of urine it can hold which causes more frequent trips to the bathroom.

the first stage of the sexual response cycle is quizlet
Answers
The first stage of the sexual response cycle is known as the "desire" or "sexual interest/arousal" phase. This phase involves the initial feelings of sexual desire and attraction towards a sexual stimulus, such as a person, an image, or a thought. It is the stage where sexual interest and motivation are initiated.
During this stage, individuals may experience physiological and psychological changes associated with sexual arousal, such as increased heart rate, heightened sensitivity, and a sense of anticipation. It is important to note that the specific experiences and sensations during this phase can vary greatly between individuals.
The sexual response cycle was originally proposed by Masters and Johnson in the 1960s, and it consists of four stages: desire, arousal, plateau, and orgasm. It is important to recognize that individuals may not always progress through these stages in a linear manner, and variations can occur based on factors such as personal experiences, individual preferences, and relationship dynamics.
