|
In translation, the rRNA poly A tail goes from the nucleus to the -------- in eukaryotes
|
cytoplasm
|
|
|
Synthesized as a single strand but if folded right the base pairs line up, and form a clover like shape. What process does this occur in?
|
translation
|
|
|
What kind of RNA is it known as after the process of transcription has completed?
|
tRNA
|
|
|
this process involves the folding of tRNA
|
Translation
|
|
|
what end of the tRNA strand does amino acid bind to during translation?
|
3'
|
|
|
What enzyme is responsible for binding amino acids to the 3'?
|
amino acyl tRNA synthetase
|
|
|
these are special nucleotides within the tRNA in the anticodon loop
|
anti-codon
|
|
|
this carries Amino acids to the site of protein synthesis
|
tRNA
|
|
|
if it is said to be charged then the tRNA....
|
has amino acid attached to it
|
|
|
if it is said to be uncharged then the tRNA...
|
does not process. Protein synthesis has already started, needs to go back and attach to another 3' end.
|
|
|
what is the difference between bacterial mRNA and eukaryotic mRNA
|
There is no poly a tail or cap in bacterial mRNA but eukaryotic does not possess ribosome binding site
|
|
|
what is the start codon for mRNA?
|
AUG
|
|
|
what is the stop codon for mRNA
|
UGA, UAG, UAA
|
|
|
what is the first amino acid in tRNA.
|
methyl or MET
|
|
|
also known as the initiator tRNA
|
methyl or MET
|
|
|
tRNA with amino acid attach is brought to the mRNA where polypeptides are usually made. This process is
|
translation
|
|
|
Eukaryotic mRNA's must under go these three types of transcriptional modification.
|
splicing, capping, and poly a tail
|
|
|
In Eukaryotics, this polymerase is used for most size categories of rRNA 285 185
|
RNA polymerase I
|
|
|
In bacteria, how many types of RNA polymerase?
|
just one type for all three types of RNA
|
