Question

Ribonucleic acid (rna) and additional deoxyribonucleic acid (dna) surrounds genes. in a process called_____, they enhance, silence, or alter genetic instructions.

Answer 1

Ribonucleic acid (rna) and additional deoxyribonucleic acid (dna) surrounds genes. in a process called methylation, they enhance, silence, or alter genetic instructions.

What is DNA methylation?

• Adding methyl groups to the DNA molecule is a biological process known as DNA methylation. Methylation has the ability to change a DNA region's activity without changing the sequence.
• When DNA methylation takes place at a gene promoter, it frequently decreases gene transcription.
• DNA methylation plays an important role in a number of critical processes in mammals, including aging, cancer, X-chromosome inactivation, genomic imprinting, and transposable element repression.
• The majority of eukaryotic genomes contain DNA methylation, a dynamic epigenetic alteration. It is well recognized to cause a high rate of CpG to TpG mutations.
• However, nothing is known about the connection between the rate of germline mutation and the dynamics of methylation during germline development.
