b) What property p it to be functional"? Explain your sr Detity (or properties) of R be replcafec Snl sh RNA c) Which of t a "functional RNAz Chthe folowing CRN mNAR (2pts) Either: i) Pick any two types what ea d) at are functional RNAs, and briefly state each one does (make clear which two you have chosen), or i) Name the three types y of RNAs that participate in translation, and state what role each plays in this process. (4pts) BONUS: Give ve an example of an enzyme or protein that has an RNA component. 0. Answer A, B or C.(Opts) ly descerihe the events that occur during DNA replication. Make sure you clearly how the process is initiated, and what happens during DNA synthesis (the describe elongation step). B. Briefly describe the events that occur during each stage of transcription in prokaryotes (initiation, elongation, termination), noting the proteins/enzymes that are needed for each step. C. Compare transcription in prokaryotes to transcription in eukaryotes. What ané the key differences? (Hint Think about differences in each stage initiation elongation, termination- and the proteins involved, and differences in processing.) dras

Answer 1

b) Messenger RNA carries the genetic information copied from double stranded DNA in the form of triplet codon, each of which specifies a particular amino acid. RNA is a single stranded which allows it to base pair with a complementary molecule.

Ribosomal RNA associates with a group proteins to form ribosomes.

c) sn RNA.

d)

Messenger RNA	Transfer RNA	Ribosomal RNA
Carries genetic information of DNA from nucleus to cytoplasm for synthesis of protein	Carries aminoacids to the ribosomes and matches them to the mRNA triplet code	Makes up ribosome with other proteins
