Question

what do you mean by genetic deletion

Answer 1

The smallest single base deletion mutations are believed to occur by a single base flipping in the template DNA, followed by template DNA strand slippage, within the DNA polymerase active site Deletions can be caused by errors in chromosomal crossover during meiosis, which causes several serious genetic diseases. Deletions that do not occur in multiples of three bases can cause a frameshift by changing the 3-nucleotide protein reading frame of the genetic sequence. The examples are given below of types and effects of deletions are representative of eukaryotic organisms, particularly humans, but are not relevant to prokaryotic organisms such as bacteria.
I think it is also called gene deletion, deficiency, or deletion mutation.
Hope it help you.

Answer 2

delation ingenetic means for example AUGGUG for removing abase G it will be taken as AUGUG
