Total questions: 20
Worksheet time: 20mins
What do we call the process of copying DNA into mRNA?
Immediately after translation what is formed?
polypetide chain (chain of amino acids)
Quaternary structure (3D) Proteins
What carries amino acids to the ribosome, while a polypeptide chain is being made?
mRNA
tRNA
rRNA
DNA
Choose the correct order for making proteins
DNA> Transcription > RNA > translation > Protein
RNA> translation> DNA> transcription > Protein
Protein> translation>RNA> translation> DNA
DNA> translation>RNA>transcription> Protein
In the initiation stage of transcription, what happens?
RNA polymerase binds to DNA at a specific site and opens it up
RNA polymerase starts making RNA from the DNA template strand
The RNA polymerase and RNA falls off the DNA
In the elongation stage of translation what happens?
The mRNA attaches to the ribosome small subunit
The ribosome adds amino acids to the A site using tRNA and forms peptide bonds at the P site
The termination factor inserts into the A site of the ribosome
What is the function of the amino acyl tRNA synthetase
Charges uncharged tRNA with their specific amino acid
Uncharges tRNA and removes their amino acid
Brings amino acids to the ribosome
before going through processing mRNA is called ____ and after it is called____
pre-mRNA, mature mRNA
immature mRNA and mature mRNA
mature mRNA and pre-mRNA
Choose all mRNA processing steps below:
3' poly A tail
5' cap
Splicing
3' cap
removal of exons
