What does Methylation of DNA prevent?
Methylation of DNA can regulate gene expression by preventing transcription factors from binding to specific regions of DNA, thereby silencing gene expression. Additionally, methylation of DNA can help stabilize the structure of chromosomes and maintain genomic stability.
Is DNA linear in prokaryotes?
Yes, DNA is typically linear in prokaryotes.
How is DNA methylation utilized in the process of DNA repair?
DNA methylation plays a role in DNA repair by helping to identify and repair damaged DNA. It can signal where repairs are needed and regulate the activity of repair enzymes. This process helps maintain the integrity of the DNA and ensures proper functioning of the cell.
Do prokaryotes possess circular or linear DNA?
Prokaryotes possess circular DNA.
How does DNA methylation regulate gene activity?
DNA methylation is a process where methyl groups are added to specific regions of DNA, which can turn genes on or off. This modification can affect how genes are read and expressed, ultimately regulating gene activity.

What protect the DNA?
Methylation protects DNA from nucleases, endonucleases
How does doxorubicin affect DNA methylation?
Doxorubicin can induce changes in DNA methylation patterns by affecting the activity of DNA methyltransferase enzymes. It can lead to global hypomethylation or hypermethylation of specific gene promoters, influencing gene expression and potentially contributing to its cytotoxic effects.
Where does methelation bind?
Methylation typically occurs on nitrogen or oxygen atoms in biological molecules such as proteins, DNA, and RNA. For example, in DNA, methylation often occurs on cytosine bases. Methylation can also occur on histone proteins associated with DNA to regulate gene expression.
Is DNA linear in prokaryotes?
Yes, DNA is typically linear in prokaryotes.
Will methylation of DNA tend to turn a gene on or off?
off

What chemical modificatin can shut down regions or newly replicated DNA?
The newly replicated DNA regions can be terminated by methylation chemical modification. Methylation is a methyl group alkylation of hydrogen atom replacement.
Who has dna domains- prokaryotes or eukaryotes?
I think prokaryotes
