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.
The types of mutations include: Missense mutation This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene.Nonsense mutation A nonsense mutation is also a change in one DNA base pair.eport Abuse. The DNA sequence of a gene can be altered in a number of ways. Gene mutations have varying effects on health, depending on where they occur and whether they alter the function of essential proteins.
