... Transfer RNA (tRNA) reads the mRNA sequence then turns it into a specific sequence of protein subunits called amino acids. It decodes and matches the amino acid sequences and places them on growing chains of proteins. One end of tRNA is an amino acid, the other end has an anticodon which is a 3-nucl ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
