Weba base sequence that is identical to the informational strand of DNA. the sequence of codons that determines the order of amino acids in the protein. an anticodon of three nucleotides that is complementary to the codon in mRNA and identifies individual amino acids. an anticodon complementary to any of the three stop codons. Question 4 WebDeamination, or the removal of an amine group from a base, may also occur. Deamination of cytosine converts it to uracil, which will pair with adenine instead of guanine at the next …

WebThere are two possible codons for glutamic acid, GAA and GAG. Single-base substitutions at the second position in both codons can produce codons that encode valine: GAA-----> GUA (Val) GAG-----> GUG (Val) Both substitutions are transversions. However, in the gene encoding the β chain of hemoglobin, the GAG codon is the wild-type codon and the … WebA temporary change in the structure of a nitrogen base due to movement of hydrogen atoms is called a(n) tautomerization, tautomeric shift, or tautomer. ...

Webpoint mutation, change within a gene in which one base pair in the DNA sequence is altered. Point mutations are frequently the result of mistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations.
