Epigenetics

Question 1

Epigenetics

Answer 1

The process that alters the gene activity without changing the DNA sequence, and leads to modifications that can be transmitted to daughter cells

Question 2

DNA Methylation

Answer 2

The addition/removal of a methyl group, predominantly where cytosine bases occur consecutively.

Question 3

DNA Methylation

Answer 3

the addition/removal of a methyl group, predominantly where cytosine bases occur repeatedly.

Question 4

Chromatin Modification

Answer 4

the modification altering the chromatin structure to influence gene expression
-tightly folded chromatin tends to shut down/ not expressed, while loosely folded chromatin is expressed.

Question 5

Imprinting

Answer 5

A condition where one of the two alleles of a typical gene pair is silenced by an epigenetic process, i.e., DNA methylation
if the expressed allele is damaged/contains a variant that increases an organism’s vulnerability.

Question 6

DNA Methylation

Answer 6

The addition/removal of a methyl group, predominantly where cytosine bases occur consecutively.
