Biotechnology is the combination of technological instruments and living cells. The DNA strands can be created from nucleic acids by DNA synthesis. Thus, option A is correct.
DNA synthesis is a biotechnolgical process that is also known as replication or duplication where the deoxynucleic acids links with the phosphate and the nitrogenous bases to form the template backbone.
The DNA synthesis produces semi-conservative replicas of the daughter strands by forming a replication fork that undergoes primer binding and elongation followed by termination.
The DNA sequencing method is used to determine the sequence of the bases or the nucleotides in the genetic material, while genetic modification and recombinant DNA are the methods to alter the genetic sequence.
Therefore, option A. DNA synthesis produces DNA strands from nucleic acids.
