BlackZzzverrR [31]2 years ago

Charles Darwin theorized that all species undergo a natural cycle of evolution in order for the species to survive and thrive within its given environment. In the case of a catastrophic event, Mother Nature will naturally find a way to support life and the organisms that are within her care.

Which of the following investigators was (were) responsible for the following discovery? In DNA from any species, the amount of
Zarrin [17]

Answer :Erwin Chargaff   a Biochemist

Explanation:

He formulated the base paring of double helix of DNA. He reasoned that since the percentage of four  DNA  bases are of this proportions in human;

                                  Adenine=30.9% and Thymine =29.4%;

                                  Guanine=19.9% and Cytosine =19.8%

Then,  the amount of adenine will always be equal to thymine,

And the amount of Guanine equals to cytosine based on this percentages of distribution.  

(Adenine and Guanine are large, molecule of Purines, while thymine and Cytosine are Pyrimidine)  

 

He concluded (although scientist believed, he did not explicitly stated this) that this should be the base paring patterns in DNA molecule. This is the first Chargaff Rule.

His second rule is that the DNA composition, in the relative amount of the four bases Adenine, Thymine, Cytosine and Guanine varies in proportion from one organisms to another. And this is the basis of molecular diversity.

How might gaps influence our understanding of the past
Veronika [31]

Answer:

The identification of gaps from systematic reviews is essential to the practice of “evidence-based research.” Health care research should begin and end with a systematic review. A research gap may not be a research need if filling the gap would not be of use to stakeholders that make decisions in health care.
