Prepare a model of DNA and give a presentation based on it

Read the following statements and find out the incorrect statements. a. The length of DNA is usually defined as number of nucleotides or base pairs present in it. b. In DNA, every nucleotide residue has an additional -OH group present at 2' -position in the deoxyribose. c. Nuclein was discovered and named by Friedrich Meisher in 1969. d. Adenine pair with Thymine and Guanine with Cytosine through H-bonds. This makes one strand complementary to the other. e. the proposition of double helical model of DNA was also based on the observation of Erwin Chargaff.

Watson and Crick model of DNA is

The double helical model of the DNA was proposed by Watson and Crick based on what data produced by wilkins and Franklin

Double helical model of DNA molecule was proposed by :

In double helix structure of DNA hydrogen bonding present between bases. The correct base pair is

According to the original model of DNA, as proposed by Watson & Crick in 1953, DNA is a-

If the length of a double helical DNA if 1.7 meters then the number of base pairs present in the DNA is
