Does lack of DNA-methylation speed up evolution?
Methyl groups are introduced to the DNA molecule through the biological process of DNA methylation. Without altering the sequence, methylation can modify a DNA segment's activity. DNA methylation often inhibits transcription of a gene when it occurs in the promoter region. DNA methylation is the name of a frequent epigenetic alteration. When DNA gets methylated, methyl groups, which each contain one carbon atom and three hydrogen atoms, are joined to the DNA's building blocks. It may not come as a surprise that many different bodily systems require the methylation cycle since it aids in both our physical and mental functioning. These include the activity of the neurological, cardiovascular, and immunological systems as well as the release of energy, heavy metal detoxification, and hormone regulation. Inactivation of the X chromosome , genomic imprinting, and the suppression of transposable elements are three significant instances of how DNA methylation influences gene expre...
