Verified
Methylated DNA sequences typically contain ____ genes.
A) transcriptionally active
B) transcriptionally inactive
C) constitutive
D) housekeeping
E) alternatively spliced
Methylated DNA
DNA in which methyl groups are added to some bases, often affecting gene expression and involved in gene regulation.
Transcriptionally Inactive
Describes genes or segments of DNA that are not being transcribed into RNA.
Constitutive Genes
Genes that are continuously expressed under normal cellular conditions, providing the basic functions necessary for the cell's survival.

Final Answer :
B
Explanation :
Methylation of DNA, particularly at cytosine bases in CpG dinucleotides, is commonly associated with gene silencing or transcriptional inactivity. This epigenetic modification can prevent transcription factors from accessing the DNA, thereby reducing gene expression.
