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: augtacagu ______
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?

\t\tmrna sequence\tamino acid sequence
gacttctaa -> ____ -> ____
gaattctaa -> ____ -> ____

Explanation:

The problem is about protein synthesis, which involves understanding mRNA codons, tRNA, and amino acid sequences. This falls under Biology (a subfield of Natural Science) as it deals with molecular biology and genetics related to protein production.

Answer:

The discipline is Natural Science, subfield Biology.
