Polypeptide chains undergo some modifications before they become fully functional. Some of these modifications include: proteolytic cleavage, lipidation and glycosylation. Proteolytic cleavage refers to the removal of some amino acids from a polypeptide chain by proteases in order for the protein to become active. An example of a substance that is modified through this process is insulin.
Answer:
d
Explanation:
When considering the frequency of the potential alleles of a gene in a population, the total must add up to 1. Think of it like percentages. an allele frequency of 0.3 means 30% of the population carry it (out of a possible 100%).
We know that the frequency of c1 is 0.3. Lets take each option and see if it can be true
a) cannot be less than 0.3. - false. It <em>could </em>be less than 0.3. For example, it could be 0.1, meaning the frequency of allele c3 would be 0.6 (because 0.3 + 0.1 + 0.6 = 1)
b) cannot be greater than 0.3. - false. It <em>could </em>be greater than 0.3. For example, it could be 0.5, meaning the frequency of allele c3 would have to be 0.2 (because 0.3 + 0.5 + 0.2 = 1)
c) is 0.7. - false. It <em>can't </em>be 0.7, because that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)
d) cannot be greater than 0.7. - true. It <em>cannot </em>be greater than 0.7, because that would mean that the frequency of c3 is 0. (0.7 + 0.3 = 1)
the characteristics applies to all three domains and viruses by the genetic material.
The genetic info is found in the nucleus.
Answer: Caecum of the intestines
Explanation:
The caecum is located in between the large intestine and the ileum and the colon. It is referred to as blind gut because one end of it is close and the other continues into the colon.
