DNA and Polypeptide Synthesis Quiz


Preview:


what is the process where: DNA is converted int mRNA code, then is carried to the cytoplasm and then to ribosomes

A. Transcription

B. Translation

C. mRNA replication


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 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


What is the role of tRNA?

A. carries specific amino acids to be joined onto the polypeptide chain

B. has start and stop codons which initiates translation and releases the polypeptide chain into the cytoplasm

C. carry genetic code from the nucleus to the ribosomes

D. essential to keep DNA protected


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


phenotype

A. physical appearance

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

Quaternary structure

A. the amino acid sequence

B. formation of alpha helices and beta sheets

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
