Following transcription, what would be the resulting mRNA sequence from this template strand: 5’-ACA GCT GTC-3’? 5' - ACA GCT GTC - 3' 5' - UGU CGA CAG - 3' 5' - GAC AGC UGU - 3' 5' - ACA GCU GUC - 3' 2 If the coding (non-template) DNA sequence of a normal gene is 5' GTC GCA TGG TGA 3', which DNA sequence would represent a silent mutation? 5' ATC GCA TGG TGA 3' 5' GTC GCA TAG TGA 3' 5' GTC GCG TGG TGA 3' None of the above. 3 A patient with xeroderma pigmentosum is prone to developing multiple skin cancers starting in childhood. This occurs because of a mutation in a gene that codes for enzymes that help repair DNA damage through the nucleotide excision repair (NER) pathways. How does NER differ from other repair mechanisms? During NER: Only one nucleotide is removed and DNA polymerase replaces the one abnormality The error in one strand of DNA is removed as well as several nucleotides on either side of the error. The gap that was removed is filled in by DNA polymerase The entire homologous chromosome is used to repair the double stranded DNA error The affected DNA strand and its complementary strand is discarded and a new double stranded DNA is created
