Answer 2

can u first tell me...do u know whether the RNApol sits on the sense strand or the antisense strand and reads the bases?

Answer 3

anti

Answer 4

correct...so the mrna sequence formed is going to be complementary to the antisense strand correct?

Answer 5

yea

Answer 6

so now according to the base pairing rule...
wherever there is C the complimentary base is G
for G it is C
for A instead of T it is going to be U (because in rna T is replaced by U)
and for T is is A

Answer 7

cn u guess the sequence now?

Answer 8

Its not C

Answer 9

or D

Answer 10

So its either A or B

Answer 11

nope...tell me the sequence..first nucleotide on antisense is A..so what would be complimentary to that in mRNA?

Answer 12

U

Answer 13

next...for T?

Answer 14

A

Answer 15

ITS D!!

Answer 16

yeah..:D
just go slow..u figured out the answer urself..dont rush to find the option..:)
