Which property of DNA double helix led Watson and Crick to hypothesise semiconservative mode of DNA replication? Explain.

Which one represents the correct manner of DNA replication?

While proposing double helical structure for DNA, Watson and Crick proposed scheme for

Semiconservative replication of DNA was first shown in

Nitrogen bases in a DNA double helix are bonded by

In DNA model of Watson & Crick, the major grooves are site of

Number of nucleotides per one turn of DNA double helix is

In an experiment, DNA is treated with a compound which tends to place itself amongst stacks of nitrogenous base pairs. As a result of this, the distance between two consecutive base pairs increases. From 0.34 nm to 0.44 nm calculate the length of DNA double helix (which has 2xx10^(9) bp) in the presence of saturating amount of this compound.

The experiments that proved the DNA in chromosomes also replicate semiconservatively were conducted by

The synthesis of identical copies of DNA is called replication (or) Duplication of DNA. DNA is duplicated so that the DNA in the New cell is identical to original DNA. Replication of DNA is enzyme catalysed process. In this 2-strands of DNA strats unconding at perticuler region. The desortion of DNA helix due to pyrimidine dimer farmation is called.
