Which discovery is attributed to phoebus levene? a. extraction and observation of dna b. identification of ribose and deoxyribose c. recognition of rna as dna’s messenger d. construction of an accurate dna model

The correct answer would be B. identification of ribose and deoxyribose.

Phoebus Aaron Theodore Levene is famous for his studies regarding the structure and function of nucleic acids.

He categorized different forms of nucleic acids which are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

He also found the components of DNA which are adenine, thymine, cytosine, guanine, deoxyribose, and a phosphate group.

He also identified deoxyribose and ribose sugars. In addition, he identified that the DNA deoxyribose and ribose

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
