Question 1
Question
what are the stages of protein synthesis
Answer
-
translation
-
DNA replication
-
transcription
-
mutations
Question 2
Question
translation is the first stage of protein synthesis
Answer
- True
- False
Question 3
Question
where does transcription occur?
Answer
-
cytoplasm
-
nuclues
-
ribosomes
Question 4
Question
what is the purpose of transcription?
Answer
-
the purpose is to for mRNA to transcribe the code for a protein and so the original DNA doesn't get damaged leaving the nuclues
-
the purpose is to use mRNA to make a protein, so it can be used for cellular functions
Question 5
Question
whats the steps of transcription?
Answer
-
free nucleotides pair up to the template strand using the complementary base pairing rule, except U replaces T, to form the mRNA strand
-
the ribosome moves along and reads the mRNA
-
the DNA strand unwinds and unzips
-
the mRNA leaves the nuclues
-
the tRNA match the codon
Question 6
Question
A three base sequence on DNA is called a codon
Answer
- True
- False
Question 7
Question
where does translation occur?
Answer
-
nuclues
-
cytoplasm on the ribosomes
Question 8
Question
what is the purpose of translation?
Answer
-
the purpose to use mRNA to make a protein, so the protein can be used for cellular functions
-
the purpose is for the mRNA to transcribe the code and so the original DNA doesn't get damaged by leaving the nucleus
Question 9
Question
whats the three base sequence on mRNA called?
Answer
-
triplet
-
codon
-
anti-codon
Question 10
Question
whats the steps of translation?
Answer
-
the polypeptide chain folds up into a functional protein
-
the mRNA leaves the nuclues
-
the mRNA moves to the ribosome
-
the tRNA anti-codon matches the codon on mRNA using the complementary base pairing rule, except U replaces T
-
the ribosomes moves along and reads the mRNA
-
the codon codes for a specific amino acid, which the amino acids bond together by peptide bonds
-
the DNA splits to expose the template and coding strand
Question 11
Question
a three base sequence on tRNA is called anti-codon
Answer
- True
- False
