To determine:
To replace the underlined word in a sentence to make it correct.
Introduction:
DNA stands for Deoxyribonucleic Acid. It is an organic compound and it has a uniquemolecular structure. It is found in all prokaryotic cells and eukaryotic cells.
The DNA structure defines the simple genetic makeup of most of the organisms.
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
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.
