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.
Silent mutations - are caused by a point mutation & have no effect of the function because they code for the same amino acid. Missense mutations - are caused by a point mutation & result in a different amino acid to be placed in the protein. Nonsense mutations - a caused by a point mutation & cause a stop where there should not be one. Frameshift mutations - are caused by an insertion or deletion of a nucleotide causing the reading frame to shift & the protein to be too long or too short.
