(3 cards)
1
Q
what is meant by epigenetics?
A
a gene-regulatory mechanism that leads to heritable changes in gene function that are not associated with changes in the DNA sequence via methylation, histone modifications, and chromatin remodelling, influencing whether a gene is transcriptionally active
2
Q
what is genomic imprinting?
A
Genomic imprinting is an epigenetic regulation resulting in monoallelic expression of either the maternally or the paternally inherited allele. In humans, this process of parental specific expression is limited to about 200 imprinted genes
