Explanation: To produce a protein, genes from DNA have to be transcripted into RNA-messenger. In other words, in transcription the DNA is rewritten with the RNA nucleotides. So, in this sense, nucleotide A from DNA pairs with nucleotide U for RNA; nucleotide T pairs with nucleotide A; nucleotide C with G and nucleotide G with C.
From the DNA sequences given, we have the following RNAm:
1.) DNA: CCT CTT TAC ACA CGG AGG GTA CGC TAT TCT ATG ATT ACA CGG TTG CGA TCC ATA ATC
RNAm: GGA GAA AUG UGU GCC UCC CAU GCG AUA AGA UAC UAA UGU GCC AAC GCU AGG UAU UAG
2.) DNA: AGA ACA TAA TAC CTC TTA ACA CTC TAA AGA CCA GCA CTC CGA TGA ACT GGA GCA

8.) DNA: TAC AGA CGG CAA CTC TGG GTG CTT TGT TCT CTT CTC AGT ATC
RNAm: AUG UCU GCC GUU GAG ACC CAC GAA ACA AGA GAA GAG UCA UAG
With the RNAm, its sequence is translated into a sequence of aminoacids. This process happens by reading a group of 3 nucleotides, named codon. Each codon is specific for 1 aminoacids. The translation begins with codon AUG, which is the start codon and ends with another specific codon.
The correspondence of codon and specific aminoacids or stop signal is called genetic code and there is a table we can use to produce the sequence of aminoacids.
The translation process will be:
1.) RNAm: GGA GAA AUG UGU GCC UCC CAU GCG AUA AGA UAC UAA UGU GCC AAC GCU AGG UAU UAG
protein: Met-Cys-Ala-Ser-His-Ala-Ile-Arg-Tyr
