QUESTION 8

Suppose a person developed a mutation in a somatic cell which diminishes the performance of the body’s natural cell cycle control proteins.

D.this individual experienced translocation resulting in chronic myelogenous leukemia

QUESTION 10

The sequence of DNA on homologous chromosomes is exactly the same.

A.True

B.False

Solution

Answer 1 C) Prophase

Reason - Prophase is the first stage in the cell division where the cell content grows until it becomes sufficient for duplication.

Answer 2 C) Anaphase

Reason - Anaphase is the 3rd stage in cell division which comes after the mitosis. during mitosis, all the chromosomes get arranged at the metaphase plate. in anaphase, these chromosomes are split into individual chromatids which are segregated into daughter cells equally.

Answer 3 A) Interphase

Reason - Interphase is the stage between two cell divisions. as soon as the cell divide, it undergoes resting and slowly preparing for the next round of cell division. this stage is the longest phase in the cell division.
