This quiz contains 11 questions from a mix of 1 subtopics.
What is the initial transcript produced by transcription called?
pre-mRNA
DNA
tRNA
mature mRNA
|
What is the process called when introns are removed and exons are joined together?
replication
splicing
translation
transcription
|
What is the function of the 5' cap in mRNA processing?
it removes introns from the mRNA
it stabilises the mRNA and assists in ribosome binding
it adds introns to the mRNA
it destabilises the mRNA and prevents ribosome binding
|
What is the function of the 3' poly-A tail in mRNA processing?
it destabilises the mRNA and speeds up its degradation
it removes exons from the mRNA
it adds exons to the mRNA
it stabilises the mRNA and delays its degradation
|
What is the role of inhibitory proteins in translational control?
they increase the rate of mRNA degradation
they increase protein synthesis
they decrease protein synthesis
they have no effect on protein synthesis
|
What is the role of activated initiation factors in translational control?
they assist in the binding of mRNA to ribosomes, initiating translation
they decrease the rate of mRNA degradation
they increase the rate of mRNA degradation
they prevent the binding of mRNA to ribosomes, stopping translation
|
What is the function of protein kinases?
they have no effect on proteins
they decrease the activity of enzymes
they remove phosphate groups from proteins
they add phosphate groups to proteins
|
What can regulate the activity of protein kinases?
cAMP
tRNA
DNA
mRNA
|
What is one example of post-translational modification?
the addition of carbohydrates, lipids, or phosphate groups to proteins
the addition of introns to proteins
the removal of carbohydrates, lipids, or phosphate groups from proteins
the removal of exons from proteins
|
are the non-coding regions of DNA that are transcribed but then removed from the pre-mRNA.
|
What is the process of adding a phosphate group to a protein called?
|
