DNA or deoxyribonucleic acid is known to be the genetic material for almost all organisms. It is tightly packed within the nucleus of every cell and wraps around the unique proteins known as histone. These histones form the loops of DNA called nucleosomes.

Further Explanation:

The genetic information is known to be packaged in 23 sets of chromosomes. In these, histones which are the proteins that aid the molecule of DNA to be very tightly packed in added and also aids in maintaining the double-helical structure of the DNA.

The thread-like structure provided in the diagram is known as chromosome. Chromosomes are found in the nucleus and it is composed up of protein as well as single molecule of DNA. The bunch like structures present is known as nucleosomes that are considered to be the basic unit of the DNA packaging.

The histone units make the structural units of the nucleosome and these units and bounded in the tight helical fiber. Finally, is the structure of DNA, which is known to be the genetic material.

I assume this photo has the labels you are talking about.

DNA double helix consists of two strands that wind around each other with their nucleotides liked.-> it's the structure number 5
nucleosome- it's a segment of DNA wound in sequence around eight histones (proteins)- number 2
Histone- proteins with DNA around them, forming the nucleosome- number 4
Tight helical fiber- chromatin coiled very tightly- 3
Cromosome- chromatin condensed even tighter forming a X shape.- 1

Describe the Watson and Crick model of DNA structure. How did it fit the data provided by Chargaff and the X-ray diffraction pat

icang [17]

DNA model given by Watson and Creek in the year of 1953 gave a very detailed study regarding the structure of B DNA which is valid till date and is essentially corroborating with Chargaff's data and Xray diffraction pattern.

<h3>Explanation:</h3>

The DNA is the most common nucleic acid found in the living organisms as a genetic material. As stated by Watson and Creek, this DNA contains a double helical structure with two sugar phosphate backbones and the nitrogen bases getting projected from it inwards. The backbones are formed of ribose sugar and phosphate and joined together with a phosphodiester bond. The ribose sugar is attached to phosphates at its 3' and 5' Carbon atoms. The nitrogen bases found in DNA are Adenine, Guanine, Thymine and Cytosine. The Adenine has two hydrogen bonds with thymine and guanine has 3 hydrogen bonds with cytosine.

Each full turn of a helix is 34A and each base pair is 3.4A apart. The distance between two strands of DNA is 20A.

Chargaff's rule regarding the equal amount of adenine and thymine as well as guanine and cytosine is matching with this structure. All the other rules also do match with this DNA structure.
