Gametogenesis, the production of sperm and eggs, involves the process of meiosis. During meiosis, two nuclear divisions separate the paired chromosomes in the nucleus and then separate the chromatids that were made during an earlier stage of the cell's life cycle.
Answer:
it is expected that the mutation results in a reduced initiation of translation and thereby decreasing the level of the protein A, while it does not change the level of mRNA A
Explanation:
Translation in bacteria starts with the formation of the initiation complex which is composed of the small ribosomal subunit, the messenger RNA (mRNA), initiation factors and the initiator transference RNA (tRNA) containing N-formyl-methionine. The small ribosomal subunit binds to a polypurine stretch of variable length in the mRNA called 'the Shine-Dalgarno sequence'. A mutation in this sequence reduces the affinity of the ribosome for the mRNA, thereby, in this case, decreasing the level of protein A. Since transcription occurs before translation, it is expected that this mutation does not change the level of expression of the mRNA A.
Answer:
associated with unstable air and stronger weather disturbance, there is more moisture in the air of a maritime air mass, increasing the possibility of rain, snow, and storms. forms over Canada, move down from North Pole, bring bitterly cold and dry air to the northern United States during the winter.
Chromosome replication must occur for the process to continue.
Arteries: any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body.
Capillaries: any of the fine branching blood vessels that form a network between the arterioles and venules.
Veins: any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.
They are all similar because not only are they all connected to the heart, but they transfer blood and nutrients all around the body. They are different by where they are located and how effective their function is.
