Structure of RNA

Question 0

Function of rRNA

Answer 0

Components of ribosomes

Question 1

Function of mRNA

Answer 1

Codes for proteins

Question 2

Function of snoRNA

Answer 2

Used in chemical modification of other RNAs

Question 3

Function of snRNA

Answer 3

Involved in RNA transcript splicing

Question 4

Function of tRNA

Answer 4

Adapter for protein synthesis

Question 5

Differences between RNA and DNA

Answer 5

1. Has ribose sugar
2. Contains uracyl instead of thymine
3. Strand: usually single but can be double.

Question 6

Non conventional pairing of uracyl

Answer 6

Uracyl can bind to both adenine and guanine

Question 7

RNA complexities

Answer 7

1. Can make triple base bonding to make complex structures
2. Hydrophobic do stack up
3. Fold on self
4. Creates bulges, internal loops and hairpin

Question 8

Pseudoknot

Answer 8

Some RNA bases twists and flips outwards and bind to each other
Flip again to form strand creating a knot like appearance

Question 9

How many bases per codon?

Answer 9

3

Question 10

Anticodon is found in what type of RNA molecule

Answer 10

tRNA

Question 11

miRNA

Answer 11

Binds to mRNA to tag for destruction

• enzyme dicer cuts mRNA at specific segment
• segment cleaved and miRNA targets and binds to it
• mRNA is the targeted for destruction
