Antworten
-
codon
-
anti-codon
-
triplet
Frage 3
Frage
there is two stages of protein synthesis; translation and transcription
Antworten
- True
- False
Frage 4
Frage
Translation happens before transcription
Antworten
- True
- False
Frage 5
Frage
where does transcription occur?
Antworten
-
nucleus
-
cytoplasm
-
ribosome
Frage 6
Frage
what happens in translation?
Antworten
-
the ribosome reads the mRNA
-
the mRNA is coded for
-
the tRNA brings the coded for amino acid to the mRNA
-
the polypeptide chain is released and folds into a functional protein
-
the mRNA leaves the nucleus
Frage 7
Frage
more than one codon, can code for an amino acid
Antworten
- True
- False
Frage 8
Frage
what is the purpose of transcription?
Antworten
-
the purpose is for mRNA to transcribe the code for a protein so the original DNA doesnt get damaged
-
the purpose is to use mRNA to make a protein that can be used for cellular functions
Frage 9
Frage
what are the types of mutations that cause frameshift?
Antworten
-
deletion
-
insertion
-
substitution
Frage 10
Frage
what type of substitution mutation changes the coded for amino acid?
Antworten
-
silent
-
nonsense
-
missense
Frage 11
Frage
what type of mutation can be inherited?
Antworten
-
somatic
-
gametic
Frage 12
Frage
what type of substitution mutation codes for a stop codon?
Antworten
-
silent
-
nonsense
-
missense
Frage 13
Frage
silent mutation is the result of redundancy due to degeneracy
Antworten
- True
- False
Frage 14
Frage
what is frameshift?
Antworten
-
when one base is inserted or deleted and the bases are moved over one resulting in different amino acids
-
when a base is swapped for another base
-
when the stop codon is coded for and results in the polypeptide chain not being completed and an unfunctional protein made
Frage 15

can mutations affect the metabolic pathway?
Antworten
-
yes
-
no
