Question

Adding an extra nucleotide to a dna sequence produces what type of mutation answers

Answer 1

The addition of an extra nucleotide to a DNA sequence produces a mutation that is called insertion. An insertion mutation can be in various sizes, from one nucleotide base pair to a section of one chromosome inserted into another. When one or more nucleotides are inserted into the genome, the processes of translation and transcription could be disrupted, resulting in altered protein synthesis.
