Question

For each sequence of DNA is shown. Write the complementary RNA sequence underneath the letters, thenuse the codon chart to determine the amino acid sequence:DNA → ​​T A C C A T G G A A T T A C T

Answer 1

Answer:

DNA → ​​TACCATGGAATTACT

RNA → AUGGUACCUUAAUGA

PROTEIN → Methionine-Valine-Proline-Stop codon-Stop codon (AUG GUA CCU UAA UGA)

Explanation:

In nucleic acids (i.e., DNA and RNA), base complementarity refers to the interaction between antiparallel strands. In the double helix DNA molecule, adenine always interacts with thymine (uracil in RNA), while cytosine always interacts with guanine. Moreover, amino acids are encoded by codons, i.e., triplets of nucleotides in the messenger RNA (mRNA). Finally, stop codons are triplets of mRNA nucleotides (e.g., UAG, UAA, UGA) that indicates the end of the protein-coding sequence.
