-
Codon
-
Triplet
-
Anti-codon
Question 2
Question
what is 3 bases called on tRNA?
Answer
-
codon
-
anti-codon
-
triplet
Question 3
Question
there is two stages of protein synthesis; translation and transcription
Answer
- True
- False
Question 4
Question
Translation happens before transcription
Answer
- True
- False
Question 5
Question
where does transcription occur?
Answer
-
nucleus
-
cytoplasm
-
ribosome
Question 6
Question
what happens in translation?
Answer
-
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
Question 7
Question
more than one codon, can code for an amino acid
Answer
- True
- False
Question 8
Question
what is the purpose of transcription?
Answer
-
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
Question 9
Question
what are the types of mutations that cause frameshift?
Answer
-
deletion
-
insertion
-
substitution
Question 10
Question
what type of substitution mutation changes the coded for amino acid?
Answer
-
silent
-
nonsense
-
missense
Question 11
Question
what type of mutation can be inherited?
Answer
-
somatic
-
gametic
Question 12
Question
what type of substitution mutation codes for a stop codon?
Answer
-
silent
-
nonsense
-
missense
Question 13
Question
silent mutation is the result of redundancy due to degeneracy
Answer
- True
- False
Question 14
Question
what is frameshift?
Answer
-
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
Question 15
Question
can mutations affect the metabolic pathway?
Answer
-
yes
-
no
Question 16
Question
what can determine a organism's phenotype
Answer
-
genotype
-
enviroment
-
nothing
-
upbringing

Answer
-
genes
-
mutagen
-
bases
-
nonsense
Question 18
Question
the definition of metabolic pathway is linked biochemical reactions controlled by enzymes that maintain life processes in organisms
Answer
- True
- False
