Final answer:
The enzyme maintenance methyltransferase recognizes only specific sequences of DNA that are methylated. It adds a methyl group to the DNA and plays a role in various biological processes.
Step-by-step explanation:
The enzyme maintenance methyltransferase recognizes only specific sequences of DNA that are methylated. It is responsible for adding a methyl group to the DNA, which helps regulate gene expression and can affect the function of the DNA. The recognition and methylation of specific sequences by maintenance methyltransferase plays a role in various biological processes, including the maintenance of genomic stability and the prevention of DNA damage.
