Answer:
The correct option is B
Explanation:
The alpha and beta-gamma subunits both can bind to target proteins. Once a G protein becomes active, its alpha subunit and beta-gamma dimer both have the ability to pass on messages in the cell via connecting or binding with other membrane proteins that are involved in the transduction of signals. In this light, B is the best option.
Answer:
D
Explanation:
Homologous chromosomes are similar but non-identical chromosomes received from each parent. They are non-identical in the sense that they may contain different alleles for the same gene. For example, in this case, D and d alleles on each homologue. These homologous chromosomes are usually involved in meiotic division, which occurs in a two-step division process; Meiosis I and II.
In meiosis I, homologous chromosomes separate/pulls apart, specifically during the anaphase stage. Alleles D and d borne on the HOMOLOGOUS pair of chromosomes are separated in the process with each of them going to either pole of the cell, according to Mendel's law of segregation.
That process is known as "Exocytosis"
So, option C is your answer.
