Answer: PCR amplification

Explanation:

If the sample amount of DNA is not enough that any research or experiment can be carried out on it, then polymerase chain reaction can be used to amplify the amount of DNA.

So, for old and poor DNA which is not present in enough quantity is amplified using this technique. In this technique the number of DNA is amplifies exponentially.

So, the correct answer is Option A

The final pattern you wish to obtain expresses the UASG-GFP construct only in cell C2. How will you drive UASG-GFP expression sp

Nat2105 [25]

Answer:

Explanation:

Here, cell C-2 needs to express GFP and therefore, GAL4 should be functional in cell C-2. This can be achieved by expressing GAL4 in Regulatory DNA construct 3, and expressing GAL80, an inhibitor of GAL4 in Regulatory constructs 1 and 2. This arrangement expresses GAL4 in columns A and C, and inhibits GAL4 due to GAL80 expression in Columns A and B; and in rows 1 and 3.

Therefore, the only cell that expresses GAL4 is cell C-2.

The arrangement is:

1. Construct 1 should express GAL80

2. Construct 2 should express GAL80

3. Construct 3 should express GAL4

4. Construct 4 should not be used
