Epigenetic modification is a change in ________________.
A
the amino acid sequence of proteins
B
the number of chromosomes in a cell
C
the nucleotide sequence of DNA
D
gene expression without altering the DNA sequence
Verified step by step guidance1
Understand that epigenetic modification refers to changes that affect gene activity without changing the underlying DNA sequence.
Recognize that these modifications can influence how genes are turned on or off, impacting gene expression.
Note that epigenetic changes do not alter the nucleotide sequence of DNA, nor do they change the amino acid sequence of proteins or the number of chromosomes.
Common examples of epigenetic modifications include DNA methylation and histone modification, which regulate gene expression.
Therefore, the key concept is that epigenetic modification changes gene expression without altering the DNA sequence.
