The answer your teacher is looking for is "gene."
A slightly more correct answer would be "allele."
That's a fairly correct answer for prokaryotes, but in eukaryotes, the explanation is complicated by introns and exons.

This is an extremely bad definition for the term gene, but I guess that is what you are looking for.
(It could also be an even worse definition of an exon; in eukaryotes, an exon is a DNA fragment encoding only a part of the polypeptide and a gene has many exons but also includes introns, promoter, regulatory region etc)

The particular sequence of amino acids in each polypeptide chain is determined by the genetic code.

sequence, that codes for a polypeptide is called Open Reading Frame (ORF).
It begins with codon for the first aminoacid- start codon, usually ATG.
And ends with stop codon, which does not code for an aminoacid, but translation ends here because there is no tRNA for stop codon.
Gene contains ORF and regulatory sequences neccessary for transcription initiation and regulation.

you should remember the golden rule "one gene = one polypeptide"... however one polypeptide can form a protein or several polypeptides conbined and linked by different chemical interactions to form a protein

i think the answer is a gene, because essentially a gene is a region of DNA that codes for a pepetide.

A "gene". We have about 30 thousand of them in our human bodies.

It is a codon as the previous poster said. Occasionally called a triplet. (as it is three nitrogen bases long...for example ACT)

In the DNA it's name is "Code" and in the mRNA is "Codon".

I think its a codon
