RNA
How many strands is RNA?
One
What comes first, transcription or translation?
transcription
How does translation know where to start and stop?
Start codon: AUG
Stop codon: UGA, UAG, UAA
Transcribe the following: ATC GTA ACC during transcription.
What is UAG CAU UGG?
a sequence of 3 nucleotides on mRNA that codes for an amino acid
codon
What is the sugar in RNA?
ribose
Where does transcription take place?
in the nucleus
Where does translation take place?
in the ribosomes (cytoplasm)
Translate the following:
AUG CGU AUG GUG GGC UAA
MET ARG MET VAL GLY (STOP)
on the bottom of tRNA, complementary to the codons on mRNA
anticodon
What is the general function of mRNA?
It creates a message of genetic information.
What types of RNA are involved in transcription?
mRNA only
It is the end result of translation.
What is protein?
Transcribe the following: GCG ACG TTG for transcription.
What is CGC UGC AAC?
what is the monomer (bead) of a protein (beaded bracelet)?
amino acid
In RNA, what is complimentary to:
A
T
C
G
A = U
T = A
C = G
G = C
What enzyme does the majority of the work in transcription?
RNA polymerase
What types of RNA are involved in translation?
mRNA, rRNA, and tRNA
Transcribe the following: TGC ATA TGC GCA ATA.
What is ACG UAU ACG CGU UAU?
chain of amino acids
protein/polypeptide
What are the three types of RNA and their function?
mRNA - code
tRNA - anticodon, brings amino acid to ribosome
rRNA - makes up the ribosome
Put the following steps to transcription in order:
a. RNA polymerase starts moving along the DNA adding complementary nucleotides as it goes.
b. mRNA is edited and leaves the nucleus.
c. When RNA polymerase hits the stop sequence of nucleotides, both RNA polymerase and mRNA are released.
d. RNA polymerase binds to a promoter.
e. RNA polymerase pulls the strands of DNA apart.
d. RNA polymerase binds to a promoter.

b. mRNA is edited and leaves the nucleus.
Put the steps to translation in order:
a. Protein chain continues to grow as each tRNA brings in its amino acid and adds it to the chain.
b. tRNA "delivers" its amino acid based on complementary pairing of a triplet code (anticodon) with the triplet code (codon) of the mRNA.
c. mRNA attaches to the ribosome.
d. Enzyme "hooks" the amino acid to the last one in the chain forming a peptide bond.

MET SER TRP GLY TYR STOP
bond that joins amino acids together
peptide
