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.
Nonsense Mutation. Gene mutation where a base-pair change in the DNA changes an mRNA codon for an amino acid to a stop codon. Instead of changing outcome, new mRNA codon is nonsense and codes for nothing. Causes premature chain termination.ase-Pair Substitution Mutation. Involves a change in the DNA such that one base pair is replaced by another. Can result in no change to protein, insignificant change, noticeable change.
