protein synthesis worksheet
background info:
proteins are large molecules composed of long chains of amino acids. the sequence, or order in which an amino acid chain is organized is determined by its mrna sequence. inside the cytoplasm within a ribosome, mrna sequences deliver their message in the form of codons
these mrna codons bind with trna molecule codons, to release a specific amino acid.
messenger rna and trna codons continue to bind until a stop codon is reached, signaling the end of the amino acid sequence the complete forming of a protein.
reading a codon chart:
use a codon chart to determine the amino acid sequence

1. identify the amino acids that will be produced from the

following messenger rna codes.
a.) aug
b.) aac
c.) cua
d.) gag

1. what would be the codon sequence(s) for the following aas?

valine:
histamine:
3.) what are mrna’s stop codons?
4.) what amino acid sequence would be made from the following
mrna sequence:
reading a codon wheel:
use the codon wheel to determine the amino acid sequence

1. identify the amino acids using the following mrna codons:

a.) guc
b.) ggg
c.) gcg
d.) cca

1. if the dna sequence: gacttctaa was changed to

gaattctaa, how would the amino acid sequence change?
mrna sequence amino acid sequence
gacttctaa -> ->
gaattctaa -> ->

Explanation:

This problem is about protein synthesis, specifically using codon charts and wheels to determine amino acid sequences from mRNA and analyzing DNA sequence changes. The subfield of Natural Science that applies here is Biology, as it deals with molecular biology and the processes of protein synthesis in cells.

Answer:

The subfield is Biology (under Natural Science).
