Epigenetic changes pass from one cell generation to the next

Epigenetic changes pass from one cell generation to the next but do not alter the DNA sequence do not pass from one cell generation to the next but do alter the DNA sequence irreversibly alter the DNA sequence and are only passed to the next cell generation if they add an advantage only occur in males alter the RNA codon - amino acid assignments of the genetic code Human somatic cells: are diploid are haploid contain germ cells are all totipotent all of the above Women have two X chromosomes while men have one; however, women don\'t make twice the amount of the proteins on the X as men. This is due to: Multifactorial factors X-inactivation Y-superiority Penetrance X-superiority

Solution

Answers:

5. A

Epigenetic changes can pass from one generation to the next but do not alter the DNA sequence.

It goes against the general notion that inheritance happens only through DNA passing from one generation to the next.

6. A

Human somatic cells are diploid and contain chromosomes arranged in pairs.

7. B

X-inactivation: It is a process of inactivation of of one of the X-chromosomes in females. The inactive X-chromosome is silenced through packing to a transcriptionally inactive form called heterochromatin.
