DNA Methylation

DNA methylation is a process by which methyl groups are added to the DNA molecule. It is an epigenetic mechanism that occurs by the addition of a methyl (-CH3) group to DNA, thereby often modifying the function of the genes and affecting gene expression.  The most widely characterized DNA methylation process is the covalent addition of the methyl group at the 5-carbon of … Read more DNA Methylation

Gene Expression

Gene Expression

Gene Expression Gene expression is the process by which the genetic code – the nucleotide sequence – of a gene is used in the synthesis of a functional gene product. It refers to a complex series of processes in which the information encoded in a gene is used to produce a functional product such as a protein … Read more Gene Expression
