Sagot :
Answer:
This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.
Explanation:
Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).
The process of the formation of new DNA from the older DNA is called replication.
The answer to the following question is semi conversation of DNA.
In the replication, there are two-strand in which one stand is template strand and the other stand is called leading strand. Both the strands act as a template strand and is being copied by the DNA polymerase.
These template strands formed the new DNA and joined it by the DNA ligase to complete it.
Hence, In DNA replication, the resulting daughter molecules contain one strand of the original parental DNA and one new strand. This phenomenon is known as semi-conservation.
