Dna methylation is one of the best-characterized epigenetic modifications and has been implicated in numerous biological processes, including transposable element silencing, genomic imprinting and x chromosome inactivation. Compared with other epigenetic modifications, dna methylation is thought to be relatively stable.

Previous studies have found indications that exposure to ionising radiation (ir) results in dna methylation changes in plants. However, this phenomenon is yet to be studied across multiple generations. Furthermore, the exact role of these changes in the ir-induced plant response is still far from understood. Here, we study the effect of gamma radiation on dna methylation and its effect across.

* repetitious words in dna represent more than half of the human genome's three billion nucleotides. 1 because human reasoning essentially views the repetition of words in spoken languages as errors, these dna sequences were first written off as meaningless junk.
Dna has a double helix shape, and segments of it consist of individual genes. In a typical human, nearly every cell contains 23 pairs of chromosomes. One member of each pair comes from the mother, the other from the father. In other words, each parent contributes half of a person’s dna, half of his or her genes.
The dna of chromosomes replicates as a cell prepares to divide. Each of the two cellular offspring inherits a complete set of genes. In each cell, the genes along the length of dna molecules encode the information for building the cell’s other molecules. Dna thus directs the development and maintenance of the entire organism.

Sep 21, 2020 epigenetic changes are dna changes that do not affect the dna sequence but a common type of epigenetic modification is called dna methylation.
Dna methylation is a biological process by which methyl groups are added to the dna molecule. Methylation can change the activity of a dna segment without changing the sequence. When located in a gene promoter, dna methylation typically acts to repress gene transcription.
Epigenetic alterations affect the structure and conformation of chromatin, but do not change the sequence of dna nucleotides; hence they do not cause mutation.
