2.2.3 - RNA: Structure

Question 1

Answer 2

Ribonucleic acid.

Question 3

Describe The RNA Mononucleotide
(3 Points)

Answer 3

~ Pentose sugar is ribose.

~ Phosphate group

~ Bases, A -> U, C -> G.

Question 4

Describe The Structure Of RNA
(5 Points)

Answer 4

~ Made up of one polynucleotide strand.

~ Each RNA polynucleotide strand is made up of alternating ribose sugars and phosphate groups linked together.

~ The sugar phosphate bonds are covalent bonds known as phosphodiester bonds.

~ These bonds form the sugar phosphate backbone of the RNA polynucleotide.

~ The phosphodiester bonds link the 5-carbon of one ribose sugar molecule to the phosphate group from the same nucleotide, which itself is linked by another phosphodiester bond to the 3-carbon of the ribose sugar molecule of the next nucleotide in the strand.
