nucleotide and nucleic acids

Question 1

describe structure of DNA nucleotide

Answer 1

phosphate
deoxyribose sugar
nitrogenous base

Question 2

describe the structure of RNA nucleotide

Answer 2

phosphate
ribose sugar
nitrogenous base

Question 3

what bases do DNA have

Answer 3

A two bonds with hydrogen T
G three bonds with hydrogen C

Question 4

what bases do RNA have

Answer 4

A with U
G with C

Question 5

which are purines
which are pyramidies

Answer 5

A + G purines
C + T + U pyramids

Question 6

differences with RNA to DNA

Answer 6

dna is double helix/double stranded
rna is single polynucleotide chains

RNA has no oxygen (ribose)
DNA has oxygen (deoxyribose)

Question 7

nucleotides join to form?

Answer 7

phosphiadaster bonds joined together by hydrogen bonds formed in condensation reactions

Question 8

3 types of rna

Answer 8

messenger rna
mrna - transfers genetic code information from DNA to ribosomes

transfer rna
trna-carry’s specific amino acids to the ribosomes

ribosomal RNA
rRNA - made of rna and proteins
