WebDeleting a whole codon again leaves most of the protein chain unchanged. Again, whether the function of the protein is affected depends on where the missing amino acid should have been and how critical it was to the way the protein folded. WebJan 10, 2024 · A 36 bp direct repeat region was observed at the beginning (position 12,473–12,508) and end (position 13,343–13,378) of the deletion regions. However, a single C/T mismatch at the sixth base of the direct repeat splits the repeat sequence into two smaller (5 bp and 30 bp) exact direct repeat sequences.

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 … WebMay 1, 2024 · A deletion mutation is a mistake in the DNA replication process which removes nucleotides from the genome. A deletion mutation can remove a single nucleotide, or entire sequences of nucleotides. Deletions are thought to occur when the enzyme that synthesizes new DNA slips on the template DNA strand, effectively missing … 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 replication,... developing a university curriculum
