Egypt's geological history has produced four major physical regions: the Nile Valley and Delta, the Western Desert (also known as the Libyan Desert), the Eastern Desert (also known as the Arabian Desert), and the Sinai Peninsula.
Abbreviation: Ks values. A synonymous mutation is a change in the DNA sequence that codes for amino acids in a protein sequence, but does not change the encoded amino acid. Due to the redundancy of the genetic code (multiple codons code for the same amino acid), these changes usually occur in the third position of a codon.
Missense mutation: In this type of mutation the altered codon now corresponds to a different amino acid. As a result an incorrect amino acid is inserted into the protein being synthesized. Nonsense mutation: In this type of mutation, instead of tagging an amino acid, the altered codon signals for transcription to stop.
