Trisomy is the term that describes the chromosomal abnormality of having three copies of a single chromosome. The outcome of this phenomena would have 47 chromosomes in the cell instead of 46. This results in the congenital malformations, serious development and moto delays and a high incidence of mortality.

Which of these pollutants is biodegradable?
vfiekz [6]

Answer:

Food waste

Explanation:

Food waste is an organic compound, unlike the other choices. Organic compounds are biodegradable because living organisms, such as decomposers, have evolved mechanisms of breaking down these large carbon-based compounds/polymers into smaller molecules for energy. Food waste is therefore easily recycled into the environment.

The others do not have naturally occurring organisms to break them down or reduce them. They would, therefore, accumulate in the environment. This is exactly what is happening to plastc pollution. Accumulation of plastic in the environment is due to fact that they are not broken down into simpler molecules by any naturally occurring bacteria or organisms in the environment.

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><u>Explanation:</u></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.
