Question

Consider the following statements and select the correct answer from the codes given below:

1. In DNA, the base adenine, guanine, thymine and cytosine are found.

2. The nucleus contains all the DNAs of a cell.

3. In RNA, thymine is replaced with uracil.

4. RNA is mainly found to be in the cytoplasm.

Codes:

(a) 1, 2 and 3

(b) 2 and 3 only

(c) 1 and 4 only

(d) 1, 2, 3 and 4

Answer 1

The correct option is:(d) 1, 2, 3 and 4

Explanation:

All the DNAs are found to be inside the nucleus of the cell. In DNA, the four nucleotide bases which are present are adenine, cytosine, thymine and guanine. But in RNA, no thymine is present instead only uracil is present which pair up with adenine. All the RNAs which are synthesized inside the nucleus during transcription, come out to the cytoplasm for becoming the template for protein synthesis (translation).
