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.
Heart and lungs works hand in hand. Not only that they are close to each other but they also work to make sure that body gets enough oxygen that it needs to live. It is the heart that pumps blood through the body it passes through the lungs. then it is the job of the lungs to supply oxygen together with the blood that heart pumps.
Answer:
α-amino group
Explanation:
The α-amino group on the hemoglobin binds with the CO2 and this action causes a conformational change in the structure of hemoglobin that ultimately causes the release of linked oxygen. When CO2 is binded to the hemoglobin the whole complex is termed as carbamino-hemoglobin.
Answer:
Also called Darwinian fitness, means the ability to survive to reproductive age find a mate, and produce offspring. Basically the more offspring an organism produces during its lifetime the greater its biological fitness.
Explanation:
Answer:
All cells are surrounded by a cell membrane. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.
