Genomes and Genome evolution/ Epigenetics Flashcards
Epigenetics
A cellular process that ALTERS gene activity WITHOUT altering the DNA sequence
What is a key factor that connects with Epigenetics?
Environmental Exposure
The epigenome is described as _____; The specific base to focus on is ____
Above the genome: Cytosine
In the epigenome, cytosine can be chemically modified by
Methyl groups being ADDED
Genome is
Sum of genetic information (in individuals)
Having a change in DNA sequence will have a
Genomic mutation
Mutation can affect in 2 ways
1) Affecting the protein code; 2) Affecting regulaiton
If a genetic change occurred in the GERMLINE
It can be heritable
Epi-Mutations are known as
Heritable epigenetics ; Changes in DNA chemicals
Imprinting is known as a process that ______; to erase____ from mom and dad to have a clean state
Specialized enzymes go through chromosomes; Epigenetic tags;
When a gene is silenced it can
Go back to sperm/egg production
Imprinting is capable of silencing the copy of the gene
that receives the chemical modification
Prader will syndrome happens when a
Active gene is missing from Chromosome 15
Prader will syndrome has the
MOMS gene imprinted
