The meselson-stahl experiment demonstrated which of the following about dna replication? view available hint(s) the meselson-stahl experiment demonstrated which of the following about dna replication? this experiment proved that dna replicated semiconservatively; half the original polynucleotide is conserved in each of the two copies. for diversity, all three processes are operational. this experiment proved that dna replicated conservatively; one of the two daughter duplexes is the conserved parental duplex, while the other is synthesized de novo. this experiment proved that dna replicated dispersively; the parental material is scattered through the structures of the daughter duplexes.

The choice of the correct answer about DNA replication examined by Meselson-Stahl is This experiment proves that DNA is replicated semi conservatively, half of the original polynucleotides are stored in each of the two copies.

DNA replication can occur with the synthesis of new nucleotide chains from the old nucleotide chains. The process uses complementary base pairs to produce a new DNA molecule that is the same as the old DNA molecule. The process that occurs is influenced by the enzyme helicase, polymerase enzyme, and ligase.

Below is a little explanation of the 3 theories that explain DNA replication:

a. The conservative, which is that the two old DNA chains remain unchanged, functions as a template for two new DNA chains.

b. Semiconservative, ie two old DNA chains are separated and a new chain is synthesized with the principle of complementation in each of the old DNA chains. Finally, two new DNA chains are produced, each containing an old printed DNA molecule and one new synthesized chain.

c. Dispersive, which is a part of the two old DNA chains used for printing new DNA chain synthesis. Therefore, the end of the study obtained the old and new DNA chains that spread on the old and new DNA chains. This replication obtains two old DNA molecules and a new DNA that links each other to each strand.

Experiments carried out by Meselson-Stahl is a continuation of experiments conducted by Watson and Crick. After successfully modeling DNA structures (Double helix), Watson and Crick predict that DNA replicates in a semiconservative way. And then in 1958, Matthew Meselson and Franklin Stahl experimented to test the three alternative hypotheses (theories) of DNA replication using the Escherichia coli bacterial DNA. The results turned out to support the semiconservative replication model predicted by Watson and Crick

Details

Class: High School

Subject: Biology

Keyword: Meselson-Stahl Experiment

answer: c

explanation:

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
