复旦大学上海医学院：《医学遗传学 Medical Genetics》课程PPT教学课件（英文）04基因突变的分子细胞生物学效应 cellular effects of gene mutation

1. Base(s) in DNA is (are) changed to other(s), or a base(s) is (are) added or removed. 2. Rearrangements of the chromosomes occur and are also considered

These entities encode information essential for the construction and regulation of proteins (such as enzymes) and other molecules that determine the growth and functioning of the organism

What is Chromatin remodeling Chromatin remodeling(染色质重构)isan important epigenetic mechanism. Chemical modification of the protruding histone tails by the addition of acetyl methyl or phosphate groups can alter chromatin structure, which in turn influences the activity of adjacent genes
