Certain DNA sequence is ACCCGTCAATTGCC. What is the sequence of tRNA?
Presuming that this is the coding strand of the DNA duplex, then following transcription of this sequence by RNA polymerase, a mature mRNA molecule will be produced that is essentially identical to the DNA coding sequence, except the pyrimidine base Thymine (T) will be replaced with a Uracil base (U). So the mRNA strand will be: 5′ – ACCCGUCAAUUGCC – 3′ your question asks for the tRNA sequence – so, as each tRNA molecule contains an anti-codon that is complementary to the mRNA codons, and because tRNA is an RNA molecule and thus contains Uracil not thymine, then the corresponding anti-codons (3 bases per tRNA molecule), will be: UGG GCA GUU AAC GGX (where X is unknown because your sequence was too short) these would produce a short polypeptide containing the following amino acids – Thr Arg Gln Leu X (X is not determined) Of course, it is also possible that the DNA sequence we start with is not the coding strand, but the template strand. The template strand is the one that is directly t
