DNA and RNA

Question 1

use of DNA

Answer 1

store genetic information

Question 2

use of RNA

Answer 2

transfer genetic material from the DNA to the ribosomes

Question 3

nucleotide structure

Answer 3

pentose sugar, nitrogen-containing organic base, phosphate base

Question 4

polynucleotide structure

Answer 4

many nucleotides joined together via condensation reactions
phosphodiester bond.

Question 5

what the chain of phosphates and sugars known as

Answer 5

sugar-phosphate backbone

Question 6

DNA structure and how does this happen

Answer 6

double helix - two separate strands wind around each other to form a spiral

Question 7

4 bases of DNA

Answer 7

adenine, thymine, cytosine and guanine

Question 8

complementary base pairing in terms of DNA and bases

Answer 8

two DNA polynucleotide strands join together by hydrogen bonds between bases.
each base will join with one particular partner

Question 9

how is RNA different to DNA

Answer 9

sugar is RNA is ribose
uracil replaces thymine as a base
nucleotides form a single polynucleotide strand
much shorter than DNA
