The expression of genes has to be carefully regulated in cells; active genes give cells their identity and ability to function... | Cell And Molecular Biology ...
Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally.
Sunburn has traditionally been attributed to UV-induced DNA damage. However, a new study reveals that RNA, another vital cellular molecule, plays a major role in triggering acute sunburn reactions.
