1. nucleotide sequence of mature mRNA is determined by:

• the amino acid sequence is determined on the order of mRNA → wrong
• nucleotide sequence of the coding region of the gene →correct
• anticodon sequence in the contributing tRNA → wrong, tRNA comes after, it doesnt old the genetic info + happens in the cytoplasm
• nucleotide of coding and regulatory sequence → WRONG, promoter, for example, doesnt encode for mRNA

1. frameshift that causes stopcodon…

• phenotype but not genotype change → wrong
• resulting protein wont be affected → wrong
• long and nonfunctional → wrong, this doesnt even make sense
• protein will be shorter and nonfunctional →correct

1. nucleotide deletion within a gene

• everything after the deletion will be incorrect

1. d
2. a
3. 5’ AGT 3’ → complemtnary sequence is 3’ UCA 5’
