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.
A missense mutation is when the change of a single base pair causes the substitution of a different amino acid in the resulting protein.This amino acid substitution may have no effect, or it may render the protein nonfunctional. single base pair substitution that results in the translation of a different amino acid at that position.
