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'

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation
