DNA and RNA

Question 1

What is RNA

Answer 1

Ribonucleic acid similar in structure to DNA main functions is to transfer genetic information from the DNA to the ribosomes. Ribosomes make protiens they read the RNA

Question 2

What is a nucleotide

Answer 2

Monomer that makes up DNA and RNA

Consist of a pentode sugar, nitrogenous base, phosphate group

Question 3

What is DNA made from

Answer 3

Pentose sugar called deoxyribose

Phosphate and A T C G base

Question 4

What is RNA made up of

Answer 4

Ribose sugar
Phosphate group
A U C G

Question 5

How do nucleotides join together and what do they form

Answer 5

Polynucleotides
Join up between phosphate group of one and sugar group of other
Bond is phosphodiester bond
Formed by condensation reaction
Chain of sugars and phosphates is sugar phosphate back bone

Question 6

What is the structure of DNA

Answer 6

Two DNA polynucleotide strands join together by hydrogen bonding between bases
Complementary bases AT GC
Contains equal amounts
2 bonds between AT
3 bonds between GC
Strands are anti parralell and twist to form double helix

Question 7

Structure of RNA

Answer 7

Single polynucleotide chain and much shorter

Question 8

What is DNA

Answer 8

Deoxyribonucleic acid used to store genetic information, all the instructions an organism needs to grow and develop
