Questão 2
Questão
what is 3 bases called on tRNA?
Responda
-
codon
-
anti-codon
-
triplet
Questão 3
Questão
there is two stages of protein synthesis; translation and transcription
Responda
- True
- False
Questão 4
Questão
Translation happens before transcription
Responda
- True
- False
Questão 5
Questão
where does transcription occur?
Responda
-
nucleus
-
cytoplasm
-
ribosome
Questão 6
Questão
what happens in translation?
Responda
-
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
Questão 7
Questão
more than one codon, can code for an amino acid
Responda
- True
- False
Questão 8
Questão
what is the purpose of transcription?
Responda
-
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
Questão 9
Questão
what are the types of mutations that cause frameshift?
Responda
-
deletion
-
insertion
-
substitution
Questão 10
Questão
what type of substitution mutation changes the coded for amino acid?
Responda
-
silent
-
nonsense
-
missense
Questão 11
Questão
what type of mutation can be inherited?
Responda
-
somatic
-
gametic
Questão 12
Questão
what type of substitution mutation codes for a stop codon?
Responda
-
silent
-
nonsense
-
missense
Questão 13
Questão
silent mutation is the result of redundancy due to degeneracy
Responda
- True
- False
Questão 14
Questão
what is frameshift?
Responda
-
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
