Answer: The DNA sequence CATCGATACCATTCGGCGCATACTTCG translates to the mRNA sequence GUAGCUAUCCUAAGCCGCGUAUGAAGC
Explanation: To translate a DNA sequence into amino acids, we need to first transcribe it to mRNA. This is done by changing T (thymine) to U (uracil). So in this case, the DNA sequence
CATCGATACCATTCGGCGCATACTTCG
transcribes to the mRNA sequence
GUAGCUAUCCUAAGCCGCGUAUGAAGC.
The next step is to divide the mRNA sequence into codons. A codon is a sequence of three nucleotides that codes for one amino acid. In this case, the codons are:
GUU (Val) GCU (Ala) UAU (Tyr) CCU (Pro) AAU (Asn) GCG (Ala) UAU (Tyr) GAA (Glu)
The sequence ends with a stop codon, which does not code for an amino acid.
Using the genetic code, we can convert each codon to its corresponding amino acid. The resulting polypeptide sequence is:
Val-Ser-Ile-Leu-Ser-Ala-Val-Stop.
Therefore, the DNA sequence CATCGATACCATTCGGCGCATACTTCG translates to the polypeptide sequence Val-Ser-Ile-Leu-Ser-Ala-Val-Stop.
Hope this helps, and have a great day!
