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.
Bio 102 Practice Problems Genetic Code and Mutation Multiple choice: Unless otherwise directed, circle the one best answer: 1.

Frameshift mutation D. Nonsense mutation E. Non-coding mutation 4. Beadle and Tatum performed a series of complex experiments that led to the idea that one gene encodes one enzyme.
