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.
Best Answer: Missense mutations With a missense mutation, the new nucleotide alters the codon so as to produce an altered amino acid in the protein product.Nonsense mutations With a nonsense mutation, the new nucleotide changes a codon that specified an amino acid to one of the STOP codons (TAA, TAG, or TGA).Therefore, translation of the messenger RNA transcribed from this mutant gene will stop prematurely.uch mutations are said to be silent because they cause no change in their product and cannot be detected without sequencing the gene (or its mRNA). Insertions and Deletions (Indels) Extra base pairs may be added (insertions) or removed (deletions) from the DNA of a gene. The number can range from one to thousands.
