Protein synthesis

Protein synthesis

Question 1 of 11

1

what are the stages of protein synthesis

Select one or more of the following:

  • translation

  • DNA replication

  • transcription

  • mutations

Explanation

Question 2 of 11

1

translation is the first stage of protein synthesis

Select one of the following:

  • True
  • False

Explanation

Question 3 of 11

1

where does transcription occur?

Select one of the following:

  • cytoplasm

  • nuclues

  • ribosomes

Explanation

Question 4 of 11

1

what is the purpose of transcription?

Select one of the following:

  • 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

Explanation

Question 5 of 11

1

whats the steps of transcription?

Select one or more of the following:

  • 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

Explanation

Question 6 of 11

1

A three base sequence on DNA is called a codon

Select one of the following:

  • True
  • False

Explanation

Question 7 of 11

1

where does translation occur?

Select one of the following:

  • nuclues

  • cytoplasm on the ribosomes

Explanation

Question 8 of 11

1

what is the purpose of translation?

Select one of the following:

  • 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

Explanation

Question 9 of 11

1

whats the three base sequence on mRNA called?

Select one of the following:

  • triplet

  • codon

  • anti-codon

Explanation

Question 10 of 11

1

whats the steps of translation?

Select one or more of the following:

  • 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

Explanation

Question 11 of 11

1

a three base sequence on tRNA is called anti-codon

Select one of the following:

  • True
  • False
