Question

Which best describes the process of insertion?

Answer 1

The term "occurs when a part of chromosome breaks off and is placed in the middle another chromosome" describes the process of insertion.

What is mutation?

• The alteration of gene sequence that cause a change in gene behavior is called as mutation.

• The sequence of DNA in chromosomes can be altered in a number of ways including substitution, deletion, duplication, insertion, and inversion.

What is insertion?

• The insertion is a process of mutation which changes the sequence of DNA by adding nucleotides to the gene sequence.
• As the result of insertion, the activity of genes can be altered, or the derived protein won't function in a proper manner.
• The segment of DNA added may be small like a single base but can bring out significant variation in size.
• Interchromosomal insertion is the insertion of a segment of the chromosome into an interstitial region of a non-homologous chromosome.
• Intrachromosomal insertion is the translocation of a chromosome segment into a different region of the same chromosome.
• The effects of insertion vary depending on the size, gene content, and orientation of the inserted fragments.
• An example of insertion mutation is fragile X syndrome.
• In this mutation, 200 CGG nucleotide repeats are inserted into the gene segment and made it non-functional.
