5. Every nucleus in your body has a duplicate set of chromosomes. The contents of each nucleus are identical. point)

A)True
B) False

B) False

Explanation:

We, as humans, are diploid organisms. This means that we possess two complete sets of chromosomes in our cells. Each set of chromosome comes from each parent that contributed to our formation i.e. one set of chromosome from our father (23 chromosomes) and the other set from our mother (23 chromosomes). Hence, humans are said to be diploid organisms with 23 pairs of chromosomes.

Each pair of chromosome is known as HOMOLOGOUS CHROMOSOMES. Homologous chromosomes are similar but non-identical chromosomes received from each parent. They are similar in the sense that they contain genes coding for same traits but they are not identical in the sense that they can contain different/contrasting alleles for the same gene.

Therefore, the chromosomal content of a nucleus of a cell in humans are not identical.
