About DNA & RNA

[wille2511]

Could you ccheck if they are correct:

This is matching with DNA and RNA enzymes
1.polymerase
2. helicases
3.topoisomerases
4.peptidyl transferase
5.single strand binding protein
6.aminoactyl tRNA synthase
7. ligase
8.primase


a. prohibits super-coiling of DNA molecule
b. repairs the 'nick' left in DNA
c. catalyze condensation bonding between amino acids
d. charges a tRNA with its proper amino acids
e. unwinds super-coiling of DNA molecule
f. catalyze the formation of a short RNA fragment
g. breaks H-bonds between base pairs
h. catalyzes addition of nucleotides to nucleic acid molecules

my answers

1)H
2)E
3)G
4)C
5)A
6)D
7)B
F

multiple choice bold ones are my answers
1a)Accuracy in the translation of mRNA into the primary structure of a protein depends on specificity in the
a)binding of ribosomes to mRNA
b)shape of the A and P sites of ribosomes
c) bonding of the anticodon to the codon
d) Attachment of the amino acids to tRNAs
e) both C and D

[MrMistery]

helicase break base pairs if i remember correctly, creating a short portion of single stranded DNA.
2 - G
3 - E

However, I am not 100% sure. I agree with the rest.

[Ammie]

I would say 1H, 2G, 3E, 4C, 5A, 6D, 7B, 8F.
