(55) Which of the following is a semi-conservative process?
A. DNA replication
B. non-disjunction
C. translation
D. transcription

DNA replication is like a master copy machine for your genetic material, splitting the original DNA strand right down the middle and creating two new strands, each containing one old and one new piece. This method not only keeps our genetic information intact but also ensures variation, which is crucial for evolution!

In the world of genetics, understanding semi-conservative DNA replication is vital! This process not only provides accurate copies for cell division but is also a direct precursor to numerous techniques in biotechnology, including cloning and gene therapy. It’s like having the ultimate blueprint for building new life, one strand at a time!
