codons and anticodons
Ribosomes are a collection of … and … that are needed for …
proteins and small RNAs , translation
what events must take place to ensure that the protein made Is the one specified by the mRNA?
tRNA must read mRNA correctly and tRNA must carry the amino acid correct for the reading
The enzyme that charges the tRNA molecules with appropriate amino acids is
aminoacyl RNA synthetase
During translation initiation, the 1st site occupied by a tRNA is the
p site
