Nucleotides

Question 1

what 3 things are nucleotides made up of

Answer 1

1) Pentose sugar (deoxyribose in DNA) (ribose in RNA)
2) nitrogenous base
3) phosphate group

all nucleotides are made up of elements C,H,O,N and P

Question 2

what are the monomers of DNA

what is the fuction of DNA and RNA

Answer 2

nucleotides

DNA stores genetic information
RNA is used to make proteins from instructions in the DNA

Question 3

what are the 4 different bases

Answer 3

Adenine
Thymine    a=t          c=g
Cytosine
Guanine
Uracil

Question 4

what are the 2 purines

Answer 4

Adenine and guanine

Question 5

what are the 2 pyrimidines

Answer 5

Cytosine and thymine

Question 6

Difference between purine and pyrimidine

Answer 6

purine has TWO carbon nitrogen rings

whereas pyrimidine only has ONE

Question 7

in RNA

what base replaces thymine

Answer 7

URACIL ( pyrimidine)
a=u
RNA is made up of a SINGLE poly nucleotide chain
whereas DNA is made up of TWO
