176. What are the traits of a tRNA molecule?
177. The tRNA molecule folds in on itself to keep itself more stable because it is not
double stranded. This results in its 5’ end and 3’ end near one another and a loop of a
specific sequence of triplet nucleotide (codon) at the other end. What is the role of the 3’
end and the codon at the loop? What is the codon at the loop called?
178. What are the 2 instances of molecular recognition for accurate translation?
179. What is “wobble”?
180. Ribosomes facilitate what in relation to protein synthesis?
181. Ribosomes are made of a large and small subunit made of protein and a ribosomal
RNA (rRNA). However it only forms a functional ribosome when what is attached to it?
182. Why does medicine that target ribosomes work on bacteria but not eukaryotes?
183. Ribosomes contain a binding site for mRNA and 3 for tRNA. Name the ones for
tRNA. What do they do?
184. There are 3 stages in translation that each require protein factors. What are the 3
stages?
185. Walk through the following diagrams. What is taking place? What are the steps?
