Body Type: DNA code- AGTGCCTTC RNA code- ___________ Amino Acid sequence (aka protein)- ___________________ Body Type?- ________

olga2289 [7]

Answer:

The correct answer would be:

mRNA sequence - UCACGGAAG,
amino acid sequence - Ser-Arg-Lys, and
body type - dwarf

By central dogma, we know that nucleotide sequence of deoxyribonuceic acid (DNA) form the amino acid sequence of a polypeptide chain.

Nucleotide sequence of DNA is first decoded in the form of nucleotide sequence of mRNA (messenger ribonucleic acid) under the process of transcription. The sequence of RNA is complementary to the nucleotide sequence of template strand of DNA. In addition, uracil is present in RNA in place of thymine.

tRNA (transfer RNA) then deciphers the codon sequence of mRNA into amino acid sequence of polypeptide sequence by the process of translation.

Now, given DNA sequence is AGTGCCTTC.

so, the mRNA sequence would be UCACGGAAG.

Codon sequence is UCA CGG AAG.

So, the amino acid sequence would be Ser-Arg-Lys.

Hence, the trait of showman performer would be dwarfism.

Codon sequence chart is attached for reference.
