Dna Replication Pearson Education

Dna Replication Pearson Education. Dna transcription is the process by which a single strand of dna is used as a template to generate a strand of mrna. Dna is reproduced by semiconservative replication.

During replication, both strands of the double helix are used as templates to make complementary, or matching, strands of dna. Histones and the associated chromatin proteins must be duplicated by new protein synthesis.

Replication in living cells the cells of most prokaryotes have a single, circular dna molecule in the cytoplasm. Helicase cuts hydrogen bonds and separates dna in half.
