The process of DNA replication begins with one double-stranded molecule of DNA. The two strands of this molecule separate during replication, and DNA polymerases add complementary nucleotides to each strand. The end results of DNA replication are two identical DNA molecules
Answer:
The correct answer would be "The sticky ends of fragmented DNA are joined with vector DNA".
Recombinant DNA or rDNA refers to the DNA that has been artificially formed by joining the fragments of DNA of two or more species.
The fragments are joined by creating the sticky ends in the DNA fragments.
These sticky ends are complementary to each other which helps the fragments to join to each other.
For example, the sticky end of a gene of interest and the sticky end of the vector DNA joined together to form a recombinant vector.
