<span>Additional facts:
A test cross between an organism whose genotype for a certain trait is unknown and an organism that is homozygous recessive for that trait so the unknown genotype can be determined from that of the offspring.
Answer:
You'd use it when you wish to see if the one that you think is a homozygous dominant is a purebred, because if you did get a recessive offspring then it proves that the animal is a heterozygous and not a purebred.</span>
Answer:
d. No longer dividing cells of the mammalian brain
Explanation:
Cell cycle consists of events that lead to the duplication of DNA and division of cell into two daughter cells. It occurs in the zygote to make more cells for building an organism. It also occurs in skin, blood and other internal organs for self renewal.
It consists of G1, S, G2 and M phase. DNA replication occurs in S phase of cell which means that it is in the process of dividing. No longer dividing cells of mammalian brain have exited the cell cycle and are in resting phase which is also called as G0. They cant form new cells hence wont have DNA replication. Thus, these cells would be least likely to contain cells in S phase.

Although amino acids may have other formulas, those in protein invariably have the general formula RCH(NH2)COOH, where C is carbon, H is hydrogen, N is nitrogen, O is oxygen, and R is a group, varying in composition and structure, called a side chain.
