What does tRNA do in translation?
30
Translation and Genetic Code
18
Joins to a specific amino acid and transfer it by
matching its anticodon to the codon on mRNA at
the ribosome
30
Translation and Genetic Code
19
What happens during initiation of translation?
40
Translation and Genetic Code
20
mRNA joins with the small ribosomal subunit,
which is then joined by a tRNA, and then joined
by the large ribosomal subunit.

In terms of transcription and translation, how
does genotype determine phenotype?
50
More Translation and Mutations
32
the information from the gene on DNA that was
inherited from parents is the genotype. It is
transcribed onto mRNA, and eventually translated
into a protein. The protein is the phenotype
(expression of the genotype)
