Translation Flashcards
from RNA language to
amino acid language
How many kinds of RNA are there?
3 kinds
What is tRNA?
Transfer RNA
What is mRNA?
messenger RNA
what is rRNA?
ribosomal RNA
RNA codes in triplets called
codons
what are codons?
groups of 3 nucleic acid bases
True or False: Codons are redundant.
True
True or False: Only one codon codes for the same amino acid
False
What does mRNA contain?
the code
what does tRNA do?
transfers amino acids
tRNA contains anticodons. What are anticodons?
correspond to codons (opposite bases)
What does rRNA match?
tRNA and mRNA by their codons/anticodons
which type of RNA joins amino acids to form a polypeptide chain?
rRNA
What are the two parts of the ribosome?
Large and small
Which enzyme loads tRNA?
aminoacyl tRNA synthase
How many kinds of aminoacyl tRNA synthase are there?
20 kinds
What does aminoacyl tRNA synthase do?
Connects amino acids and tRNA
What is the start codon?
Methionine (AUG)
Where do codons begin?
at the start codon
What are the stop codons?
UAA, UAG, UGA
what happens at the a site?
codons are matched to anticodons
at the p site,
amino acids are joined to create a polypeptide chain
at the e site,
empty tRNA is ejected from the ribosome
