Which of the following base pairs are found in DNA and which of them in RNA ?
(i) `A:A `
(ii) `A:T`
(iii) `C:G`
(iv) `G:C`
(v) `G:A`
(vi) `A:U` ,
(vii) `G:U` and
(viii) ` A:C` .

Explanation

To determine which base pairs are found in DNA and which are found in RNA, we need to understand the base pairing rules for both nucleic acids.

### Step-by-Step Solution:

1. **Identify the Bases in DNA and RNA**:
- **DNA Bases**: Adenine (A), Thymine (T), Cytosine (C), Guanine (G)
- **RNA Bases**: Adenine (A), Uracil (U), Cytosine (C), Guanine (G)
