Answer:

It is necessary because of the base pairing between the desired gene and plasmid

Explanation:

Restriction enzymes are enzymes that recognize the specific DNA sequence-restriction site, double-stranded cut DNA and produce ends with a single-stranded overhang. The overhangs of the plasmid can stick together with overhangs of gene of interest by complementary base pairing.  Joining of ovarhangs is done by the enzyme DNA ligase.

The round pea seed trait is dominant over the wrinkled pea seed trait. If the phenotype of a pea seed is wrinkled, which combina
vovikov84 [41]

The wrinkled pea will have two recessive alleles on the locus.

Explanation:

Two forms of same gene are called alleles of that gene.

The allele that expresses itself under heterozygous condition is called the Dominant allele.

The recessive allele can express itself only if they are under homozygous combination i.e. both the alleles on homologous chromosome are recessive.

Here wrinkled pea is a recessive trait and if it is expressed in the phenotype then the genotype of the plant must be homozygous for the recessive allele.
