Answer 4

thymine and cytosine and uracil

Question 5

what end is nucleotides added to

Answer 5

3 prime end

Question 6

mRNA

Answer 6

Messenger. carries a copy of the genetic code from nucleus to ribosome

Question 7

tRNA

Answer 7

transfer. carries amino acids from cell cytoplasm to the ribosome, and pairs with the complementary code carried by the mRNA

Question 8

rRNA

Answer 8

Ribosomal. comprises 60% of the structure, the other 40% is protein

Question 9

differences between DNA and RNA

Answer 9

dna is double stranded, rna in single
dna contains deoxyribose, rna contains ribose
dna uracil is replaced with thymine
dna in membrane bound organell
rna in cytoplasm of eukaryotic cell
