semiconservative adjective semi·con·ser·va·tive-kən-ˈsər-vət-iv :relating to or being genetic replication in which a double-stranded molecule of nucleic acid separates into two single strands each of which serves as a template for the formation of a complementary...
sem·i·con·ser·va·tive replication (sĕm′ē-kən-sûr′və-tĭv, sĕm′ī-) n. The normal process of DNA synthesis, in which the two original strands of the molecule separate, and each strand acts as a template for the synthesis of a new, complementary strand. Each new...
The first stage of DNA replication involves the unwinding of the double strand of DNA (DNA double helix) and separating them by breaking the hydrogen bonds between the bases. This is done by the enzymehelicase. 2. Each separated strand now is a template for the new strands. There are many...

To determine who proposed the semiconservative replication of DNA, we can follow these steps:1. Understand Semiconservative Replication: - Semiconservative replication is a method of DNA replication where each of the two st

DNA replication is: A) Conservative B) Semiconservative C) Nonconservative D) Dispersive DNA Replication: DNA is replicated prior to cell division so that the daughter cells can each have their own copy of the genome. In the case of mitosis, each daughter cell obtains ...
Step-by-Step Solution:1. Understanding the Question: The question asks about the first demonstration of semiconservative replication of DNA. 2. Identifying Key Scientists: The experiment
