Due to a recessive mutation in gene A, amino acid ‘Glu’ in position 25 of polypeptide A (the wild polypeptide) is replaced by ‘Ala’. Individuals who are homozygous for the mutant allele (aa) don’t have any phenotypic alterations. Based on this observation, which of the following IS TRUE? A. The mutation has occurred in the promoter. B. The mutation has occurred in one of the introns of the encoding gene. C. The mutation was a base substitution in one of...

Suppose that a mutation occurs in an intron of a gene encoding a protein. Explain what effect this mutation will have on the protein’s amino acid sequence?

DNA to Protein Describe the mutation that created the HbS allele: type of mutation, location of mutation on HbA sequence (# of bases from beginning of sequence), nucleotide change (from which base to which base?). Describe the effect of this mutation on amino acid sequence of beta-globin polypeptide chain: effect of mutation on codon, which amino acid was changed (# amino acids from beginning of chain), what was the amino acid change (from which amino acid to which amino acid?)...

Match each type of mutation to the correct example. Nonsense mutation A codon in the PAH gene with a C-to-T mutation still specifies leucine. Silent mutation An allele of the CFTR gene where a codon mutated from AAG to TAG. Missense mutation A GGT (glycine) to GAT (aspartic acid) mutation in the KRAS gene A 2 base pair deletion in the ORF of the gene encoding the Retinitis Pigmentosum GTPase Regulator Frameshift mutation Promoter mutation A T-to-G mutation - 35...

Which term refers to a point mutation that results in different amino acids in a particular position due to substitution of one base for another? 1) missense mutation 2) silent mutation 3) nonsense mutation 4) frameshift mutation 5) translocation mutation
The gene encoding protein Bog in E. coli has been changed by a point mutation in...
The gene encoding protein Bog in E. coli has been changed by a point mutation in its open reading frame. Originally the gene encoded a 108 amino acid long functioning protein whose amino acid composition favored nonpolar and negatively charged amino acids. After the mutation it encodes a 110 amino acid long non-functioning protein that is now rich in polar uncharged amino acids and positively charged amino acids. Which mutation scenario best explains this observation. A) A frame-shift caused by...
A substitution mutation is one in which one nucleotide base is changed to another
2. A substitution mutation is one in which one nucleotide base is changed to another Suggest ONE substitution A G mutation in the DNA that would cause the first amino acid in the "# of Eyes" gene to change from alanine (Ala) to valine (Val). In the table below, write the original.3. There is a substitution mutation in the gene for Fangs in which the first DNA base changes from guanine to thymine. The mutation results in a genetic disorder...

5. If a mutation happens in the DNA that changes the T at base 14 to a G:
Genetic Code: The dictionary of the language of life Use the Genetic Code as a "dictionary" to solve the exercises on next page 5. If a mutation happens in the DNA that changes the T at base 14 to a G: a) What would be mutated sequence of nucleotides in the corresponding codon in the mRNA and the anticodon in the tRNA? Is there any change in the corresponding amino acid in the protein? b) What is the name of this type of...

This question is about DNA damage, repair and mutation. a) State a type of mutagen that could produce a single base pair substitution mutation. Briefly describe how this mutagen can produce single base pair substitution mutations. [4 marks] b) For your mutagen from (a), briefly describe the repair process that could repair the DNA damage. [4 marks] c) Propose how a single base pair substitution can be a hypomorphic allele. Explain how your mutation fits the definition of a hypomorphic...
