Polypeptide - answer A linear chain made of multiple peptides.
Protein - answer A functional unit made up of one or more
polypeptides.
Amino Acid - answer Simple organic compound containing carboxyl
and amino groups.
Transcription - answer The process of a gene (DNA) being copied
complimentary (mRNA) in the nucleus. (Uracil replaces thymine).
Process of Transcription - answer Initiation, elongation, termination
Initiation - answer Promoter sequence found by RNA enzyme on
sense strand.
, Elongation - answer Process of reading and producing pre RNA.

on tRNA.
Nitrogen Bases - answer Adenine+Thymine, Guanine+Cytosine.

reading of DNA where uracil replaces thymine).

Secondary Structure - answer Regular, repeated patterns of folding
the protein backbone (Alpha helix and Beta sheet).
