Multiple Choice It is an enzyme required to produce a primer needed for DNA replication O It is an enzyme that catalyzes the addition of nucleotides to the 5' end of a growing DNA strand, O It is an enzyme that catalyzes the addition of nucleotides to the 3' end of a growing DNA strand. It is an enzyme required to glue pieces of DNA fragments together. It is an enzyme that polymerizes the DNA and keeps the replication fork open

The rate of transcription for a gene is found to be affected by a mutation. Where would you expect the mutation to appear on the DNA? Multiple Choice In an intron associated with the gene In the promotor for the gene In a splice site for the gene O In the rRNA of the ribosomes translating the gene In the exon of the gene

Sweo What would result from a single nucleotide deletion (point mutation) within the coding sequence of a structural gene? Multiple Choice a silent point mutation with no deleterious effects a mis sense point mutation resulting in the change of one amino acid a nonsense point mutation resulting in the generation of a premature stop codon a frameshift mutation, producing a different amino acid sequence altogether All of the choices are possible.
