DNA is sequenced at
a. |
step 2 only. |
|
b. |
step 1 only. |
|
c. |
steps 2 and 3. |
|
d. |
steps 1 and 2. |
|
e. |
step 3 only. |
Ans:
a. Only step 2 only
Explanation: DNA is isolated from the sample in the step 1. So, step 1 is DNA isolation step. The isolated DNA is sequenced in the step 2. So, step 2 is DNA sequencing step. In step 3, the sequenced DNA are compared to other known sequences. So, step 3 is data analysis step.
