Protein, DNA, RNA
RNA, DNA, Protein
DNA, RNA, Protein
Protein, RNA, DNA
RNA has what base that is instead of thymine?
guanine
adenine
thymine
uracil
What enzyme does transcription use?
DNA polymerase
ligase
RNA polymerase
helicase
Which RNA carries the message?
mRNA
rRNA
tRNA
Where does transcription take place? Check all that apply.
nucleus of eukaryotes
nucleus of prokaryotes
cytoplasm prokaryotes
smooth ER
What is the building block, monomer, of the biomolecule, Nucleic Acid?
RNA must be edited before it can be used to make Proteins, what happens during this editing process?
A spliceosome cuts out exons, reconnects the introns
A spliceosome cuts out the introns, reconnects the exons
A splicesome pairs nucleotides with the DNA base pairs
The RNA is checked for typos
RNA contains which sugar?
deoxyribose
Ribose
glucose
fructose
Where on the DNA strand does RNA polymerase attach?
Complainer
Enforcer
Promotor site (TATA box)
Polymerator
The______ region lies towards the 3'end of the coding sequence of DNA since the transcript is made ___.
Promoter, 5'-3'
Terminator, 5'-3'
Promotor, 3'-5'
Structural genes, 3'-5'
Removal of noncoding sequences from the pre-RNA is called
Capping
Splicing
Tailing
Spooling
Capping is addition of _____ towards the 5' end of mRNA
Methyl cytosine
the GTP cap
GDP tail
poly - A tail
A poly A tail is added to the mRNA (check both answers that apply)
by accident, the enzyme RNAP is stuck and adds more A's
to provide time for the mRNA to be read in the cytoplasm before it is generated
so that RNA'se enzymes (exonucleases) will cut off A's and leaving the coding sequence in tac longer.
to provide direction out of the nucleus into the cytoplasm
Select the true statement.
The whole DNA antisense strand is transcribed
Both sides of the DNA strands are encoded into mRNA.
The gene section of a DNA antisense strand is transcribed.
The gene section of the double helix is transcribed.
Which statement is true?
A gene is expressed all the time.
All genes in our chromosomes are expressed at the same time frame of life.
A gene is expressed when needed, otherwise it is 'silent'.
All genes are expressed all the time.
The triplet code, codon, that signals the start of a code in mRNA is __.
GGG
AUG
AUU
Did we do this already? yes, yes it is there...in your pogil
