What is the difference between the control group and the experimental group in a experimental study
Ierofanga [76]

The experimental group is going to be where you “experiment” and change the normal conditions to see what outcome will occur ( under different conditions then normal )

umka2103 [35]

Answer:

Primers should be:

3 'ACGTATGTCGCTTAGT 5'

5 'ACGTTCCAGTCAATGA 3'

Explanation:

DNA replication occurs with the need for the presence of primers that are a small sequence of nitrogenous bases that will allow the initiation of replication.

Primers are extremely important in PCR and are represented as small pieces of single-stranded DNA that specify the region of DNA that should be replicated during PCR. These primers attach to the single strand of DNA by pairing the nitrogenous bases allowing the DNA polymerase to recognize where replication begins.

Regarding the question above, the primers should be:

3 'ACGTATGTCGCTTAGT 5'

5 'ACGTTCCAGTCAATGA 3'
