1what is 3 bases on DNA called?
- ACodon
- BTriplet
- CAnti-codon
2what is 3 bases called on tRNA?
- Acodon
- Banti-codon
- Ctriplet
3there is two stages of protein synthesis; translation and transcription
- ATrue
- BFalse
4Translation happens before transcription
- ATrue
- BFalse
5where does transcription occur?
- Anucleus
- Bcytoplasm
- Cribosome
6what happens in translation?
- Athe ribosome reads the mRNA
- Bthe mRNA is coded for
- Cthe tRNA brings the coded for amino acid to the mRNA
- Dthe polypeptide chain is released and folds into a functional protein
- Ethe mRNA leaves the nucleus
7more than one codon, can code for an amino acid
- ATrue
- BFalse
8what is the purpose of transcription?
- Athe purpose is for mRNA to transcribe the code for a protein so the original DNA doesnt get damaged
- Bthe purpose is to use mRNA to make a protein that can be used for cellular functions
9what are the types of mutations that cause frameshift?
- Adeletion
- Binsertion
- Csubstitution
10what type of substitution mutation changes the coded for amino acid?
- Asilent
- Bnonsense
- Cmissense
11what type of mutation can be inherited?
- Asomatic
- Bgametic
12what type of substitution mutation codes for a stop codon?
- Asilent
- Bnonsense
- Cmissense
13silent mutation is the result of redundancy due to degeneracy
- ATrue
- BFalse
14what is frameshift?
- Awhen one base is inserted or deleted and the bases are moved over one resulting in different amino acids
- Bwhen a base is swapped for another base
- Cwhen the stop codon is coded for and results in the polypeptide chain not being completed and an unfunctional protein made
15can mutations affect the metabolic pathway?
- Ayes
- Bno
16what can determine a organism's phenotype
- Agenotype
- Benviroment
- Cnothing
- Dupbringing
17what are the things that cause mutations called?
- Agenes
- Bmutagen
- Cbases
- Dnonsense
18the definition of metabolic pathway is linked biochemical reactions controlled by enzymes that maintain life processes in organisms
- ATrue
- BFalse
