A section of DNA has this base sequence: AGCGTTACCGT. A mutation in this DNA strand results in this base 
sequence: AGGCGTTACCGT. What type of mutation does this change represent?

A virus infects a cell and randomly inserts many short segments of DNA containing a stop codon throughout an organism's chromosomes. This will probably cause __________.

Which type of mutation is least likely to affect protein function?

A particular mutation had no effect on the polypeptide encoded by a gene. This mutation probably involves __________.

If a base-pair change occurs in DNA, thisa. is a mutation.b. would be a mutation only if it falls in a protein-coding part of a gene.c. would be a mutation only if it falls in a transcribed part of the genome.d. is not a mutation, because only one base pair has been altered.

Imagine discovering a loss-of-function mutation in a eukaryotic gene. You determine the gene's nucleotide sequence from the start site for transcription to the termination point of transcription and find no differences from the wild-type sequence. Explain where you think the mutation might be and how the mutation might be acting.

A geneticist found that a particular mutation had no effect on the polypeptide encoded by a gene. This mutation probably involveda. deletion of one nucleotide.b. alteration of the start codon.c. insertion of one nucleotide.d. substitution of one nucleotide.
