Mutations are spontaneous and occur at random however there are some mutagenic agents which increase the chance of this happening such as radiation exposure. If it is a point shift mutation then only a few bases on the dna sequence are changed so only changes a few of the amino acids in that chain (such as inversion of a base). If its a frame shift then the base sequence is altered so much so that every amino acid from after that changes (such as deletion of a base) which can create things such as cri-du-chat syndrome which results from a piece of chromosome 5 is missing. Hope this helps:)
Reverse transcriptase use mRNA to
form DNA apex
Reverse transcriptase is a broad
family of enzymes that play a unique role in the flow of genetic information. The
synthesis of DNA from an RNA template through reverse transcription produces
complementary DNA. Reverse transcriptase use an RNA template and a short
primer complementary to the 3' end of the RNA to direct the synthesis of the
first strand complementary DNA, which can be used directly as a template for
the Polymerase Chain Reaction.
