DNA and Polypeptide Synthesis Quiz
Preview:
What is not a role of mRNA?
A. essential to keep DNA protected
B. carry genetic code from the nucleus to the ribosomes
C. has start and stop codons which initiates translation and releases the polypeptide chain into the cytoplasm
D. carries specific amino acids to be joined onto the polypeptide chain
How are cells differentiated?
A. the way that the DNA molecules are organised and packaged
B. how big they are
C. what nitrogenous bases they have
Primary structure
A. the amino acid sequence
B. formation of alpha helices and beta sheets
C. secondary folding caused by the interaction between the polypeptide and its immediate environment, results in the formation of overall 3D structure
D. the relationship between individual subunits
What is the process where: mRNA is read within the ribosome, where associated anticodons are paired up, leaving their amino acid, creating a polypeptide chain.
A. Translation
B. Transcription
C. Translocation
Secondary structure
A. the amino acid sequence
B. formation of alpha helices and beta sheets
C. secondary folding caused by the interaction between the polypeptide and its immediate environment, results in the formation of overall 3D structure
D. the relationship between individual subunits
Quaternary structure
A. the amino acid sequence
B. formation of alpha helices and beta sheets
C. secondary folding caused by the interaction between the polypeptide and its immediate environment, results in the formation of overall 3D structure

What is the role of tRNA?
A. carries specific amino acids to be joined onto the polypeptide chain

Tertiary structure
A. the amino acid sequence
B. formation of alpha helices and beta sheets
C. secondary folding caused by the interaction between the polypeptide and its immediate environment, results in the formation of overall 3D structure
