In point mutation, either substitution or frame shift, the DNA base sequence is altered. Whereas substitution mutation involves the replacement of a DNA nucleotide with a nucleotide having a different nitrogenous base, a frame shift mutation is a result of insertion or deletion of nucleotide in the DNA. Still, silent mutation is a type of substitution mutation wherein the base substitution in the DNA does not affect the coded amino acid.

This substitution has only led to a codon which codes for the same amino acid—glycine Enger, Ross, and Bailey, On the other hand, chromosomal mutations are triggered by the chromosomal rearrangements with alteration or non-alteration in the chromosomal number.

Each codon codes for an amino acid and so when each codon is read, a corresponding amino acid is activated. A tRNA molecule has two ends: Appropriate tRNA molecules attach to and carry the activated amino acid to the ribosome. Anticodons pair with codons to bring the specific amino acid to the correct place.

The ribosome reads the next codon and another tRNA comes along to repeat the process. As tRNA come and go, amino acids link together, forming more peptide bonds. Then Eventually, a polypeptide chain is synthesized and it undergoes its changes to carry out its function as a protein. Protein synthesis is the production of a polypeptide based on a certain region of the genetic code in DNA. It occurs in two stages, transcription, which takes place in the nucleus, and translation, which takes place in the cytoplasm.

DNA replication or DNA synthesis is the process of copying a double-stranded DNA molecule. This process is important in all known forms of life and the general mechanisms of DNA replication are the same in prokaryotic and eukaryotic organisms.

DNA Replication To understand the process of DNA replication, you much first be familiar with the structure of DNA. Resembling a twisted ladder, DNA is a double helix formed with nucleotides, a phosphate and sugar backbone, and nitrogenous bases.
