Question

1. Which of the following is true about RNA?

A) It is primarily double-stranded

B) It has a phosphate and deoxyribose backbone

C) It has the same purine bases as DNA, but differences in the pyrimidine base usage

D) It is primarily short, with simple and random structure

E) None of the above

2. Which of the following is not true about RNA?

A) It is primarily single-stranded

B) It has a phosphate and a deoxyribose backbone

C) It has the same purine bases as DNA, but differences in the pyrimidine base usage

D) It is primarily short, with simple and random structure

E) None of the above

3. RNA differs from DNA in its:

A) base usage

B) backbone structure

C) folding patterns

D) length

E) All of the above

4. The ribose sugar found in RNA is an isomer of the one found in DNA

A) True

B) False

5. Uracil is an isomer of Thymine

A) True

B) False

1. C
It have same pyrimidine as DNA A and G but but there is a change in pyrimidine in place T it have U.

2. B

It have ribose sugar in place of Deoxyribose of DNA.

3. E

All given things are different in RNA in compare to DNA.

4. B False

it is not a isomer in DNA one OH group is removed that is why it is deoxyribose sugar.

5. B False

The only difference between it and thymine is the presence of a methyl group thymine
