Genes, proteins, mutations

transcribe and translate each of these 3 following DNA gene sequences'
1. 3'-TACCCTTTAGTAGCCACT-5 original gene sequence
2. 1 3'-TACGCTTTAGTAGCCATT-5' mutated gene sequence.
3. 2 3'-TAACCTTTACTAGGCACT-5' mutated gene sequence
What is the significance of the first and last codons of an mRNA transcript.
what meaning do these mRNA codons have for protein synthesis?
did the mutations result in a change in the final proteins? If so, describe the change.
In general, why might a change in amino acid sequence affect protein function?
complete a PUNNETT SQUARE FOR CYSTIC FIBROSIS USING ALLELES: C =
normal allele;c=allele for CYSTIC FIBROSIS. Based on the Punnett Square calculate %'s for having a health child (not a carrier), a child that is a carrier for the Cystic Fibrosis trait, and a child with Cystic Fibrosis
