Which of the following DNA sequence indicates chromosomal duplication ( mutation) if the normal sequence is
5' CTAGTTGCAAT 3'
5' CTAGTTGTTGCAAT 3'
5' CTAGTGCAAT 3'
5' ATCGTGCAAT 3'
5' CTAGTGCTAA 3'



Answer :

The DNA sequence indicates chromosomal duplication ( mutation) if the normal sequence is 5' CTAGTTGCAAT 3'.

Replication, as it relates to genes, refers to a type of mutation in which there is one or more copies of a DNA segment. A mutation is a remake in the DNA sequence of an organism. DNA changes during cell division, exposure to errors in reproduction. can result in mutagenesis or viral infection.Reverse tandem duplication occurs when the gene sequence in the duplicated region is exactly different from the normal sequence. In offset transfer, the duplicated area is not close to the normal part.
