Answer:
<h2>
Phosphorylation and dephosphorylation plays an important role in activating or inhibiting different proteins.</h2>
Explanation:
1. When Cdc25 is phosphorylated by M-Cdk, it activates the CdC25. It acts as checkpoint from G1 to S and G2 to M.
So, the correct answer is activates (A).
2. Phosphorylation of condensins by M-Cdk, degrades the condensin and begins the decondensation of chromosomes. That means it inactivates the condensin.
So, the correct answer is Inactivates (I).
3. Phosphorylation of APC/C activates it and then CdC20 can bind to it and then cell will progress through anaphase.
So, the correct answer is Activation (A).
4. Phosphorylation of Ndc80 by Aurora-B leads to binding of NdC80 to kinetochore and recruits the Ska complex at kinetochore.
So the correct answer is activates (A).
So, four-letter string is AIAA.
Answer:
Cells are the basic building blocks of living things. ... Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions
Explanation:
Answer:
The answer is: Linkage disequilibrium at alleles controlling the sexually selected trait and fitness bind them together evolutionarily.
Explanation:
Indirect selection can be said to operate at one locus resulting in genetic correlation with another locus, which is the main goal in the selection process. During the process of sexual choice, this commonly occurs when one preferred allele diffuses because it is out of balance with other alleles, which are benefited by natural selection or sexual selection.
Answer:
Experiment 4. Relaxed, the drug will stop the calcium so that it does not act on the troponin
Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.
Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.
Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.
Answer:
If red blood cells are placed in a 0.3 M NaCl solution, there is little net osmotic movement of water, the size and shape of the cells stay the same; the NaCl solution is isotonic to the cell.
