Answer to Problem 1A

The word which can be filled to replace nucleosome is double helix. So the correct sentence is “the twisted ladder shape of DNA is called double helix”.

Explanation of Solution

DNA was first identified by theFriedrich Miescher in 1869 during his research on white blood cells. Later, James Watson and Francis Crick proposed a model for the double helix structure of a DNA molecule.

DNA is a long polymer of nucleotides and the components of nucleotide are nitrogenous base, phosphate group and a sugar.

The 4 Nitrogenous bases that are present in DNA are Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).

These nitrogenous bases pair together in the following manner: A with T, and C with G. These base pairs are essential for the DNA’s double helix structure, which resembles a twisted ladder.
