Mutacja punktowa – rodzaj mutacji polegający na zmianie pojedynczego nukleotydu w DNA lub RNA. Podział mutacji punktowych. Ze względu na przyczyny. Mutacje punktowe mogą powstawać w wyniku substytucji, delecji (pominięcia) lub insercji (addycji) pojedynczego nukleotydu [1].

5 dni temu · A point mutation is a change in a single base pair of DNA that can affect gene expression or protein function. Learn how point mutations occur, what types of consequences they can have, and how cells deal with them.
Point mutation is a change in a single base pair of DNA that can affect the protein sequence and function. Learn about the causes, effects and types of point mutations, such as transition, transversion, silent, missense and nonsense mutations.
A mutation (Section 14.1) is a change in the nucleotide sequence of a short region of a genome (Figure 14.1A). Many mutations are point mutations that replace one nucleotide with another; others involve insertion or deletion of one or a few nucleotides.
