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.
Answer:
Father should give her healthy food
Explanation:
when mother eat healthy food the child which was in the womb of her will get nutritional energy then child health will be nice.
Answer:
Given the nature of descriptive statistics, psychologists will use descriptive statistics to assemble data about their clients through their observations of clients' behavioral patterns. Then a sample of the data will be taken. The sample is summarized statistically, interpreted, and recorded. Psychological reports can be issued based on the observed statistical results.
Explanation:
Psychologists and other occupations use descriptive statistics to describe the basic features of the data in their studies or experiments. Descriptive statistics provide simple generalizable summaries about the observed sample and the calculated measures. Using simple graphics, they form the basis of quantitative data analysis.
Evolution maybe?
