DNA replication is:
Correct answer: C. Semidiscontinuous and semiconservative
- A. Continuous and conservative
- B. Discontinuous and semiconservative
- C. Semidiscontinuous and semiconservative
- D. Conservative and semidiscontinuous
Explanation
Replication is semiconservative because the new daughter DNA synthesized is composed of one parent DNA and one newly synthesized complementary strand of that molecule.Semi-discontinuous because during replication there are 2 complementary strands synthesized that run anti-parallel. The DNA polymerase can only add nucleotides to a 3' end. This results in one strand synthesized continuously, called leading strand and the other synthesized discontinuously, called lagging strands.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
