Cyclin B1, a key cell cycle regulatory protein in vertebrates, is mostly cytosolic before mitosis. Early in mitosis, however, th

e protein is phosphorylated by certain protein kinases and consequently accumulates in the nucleus. How can phosphorylation bring about nuclear accumulation of this protein?

Answer:

Phosphorylation within the nuclear export signal interferes with the function of the  signal.

Explanation:

In biochemistry, phosphorylation is the addition of a phosphate group (PO4) to a protein or other molecule. Phosphorylation is a major player in protein regulation mechanisms, preventing protein-catalyzed reaction product from accumulating in the body causing problems.

However, in some cases phosphorylation may cause nuclear accumulation of a protein in the nucleus of the cell. An example of this is the protein shown in the question above. In this case, phosphorylation in the nuclear export signal interferes with the signal function, resulting in protein accumulation in the nucleus.

An organism has a haploid number of 6. How many possible assortments of chromosomes are possible based on the independent assort
USPshnik [31]

Answer:

64

Explanation:

Assortment of chromosomes according to Mendel, is when alleles on the chromosomes get separated into gametes independenly of one another. Independent assortment reshuffles or rearranges the chromosomal pair in the resulting gametes. 2^n is a mathematical expression that can be used to determine the number of possible chromosome combinations, which n is the number of chromosomes that can be present in one gamete.

In this case, the organism has an haploid number of 6, meaning that 6 chromosomes can be present in the gamete. Hence, 2^6 will give rise to 64 possible combinations of chromosomes in each gamete.
