Which discovery is attributed to phoebus levene

This difference made him propose that the nuclein of the animals was the deoxyribose nucleate -now called "deoxyribonucleic acid" or DNA, while the vegetables contained ribose nucleate or ribonucleic acid or RNA.

He was able to isolate the sugars ribose and deoxyribose from the nucleic acids, which are an important part of their structure. He also determined how the nucleic acid components combine to form the nucleotides, the basic building blocks of nucleic acids, and how the nucleotides combine in chains to form the polymer.

Weegy: Because it couldn't raise money, the US government could not pay debts owed from the Revolution or easily secure Why does DNA pol I carry the number one? It contains a form of DNA pol III that can add new nucleotides to either the 5' end or the 3' end of an existing strand. All other properties of the enzyme remain unchanged.

The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide. The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar deoxyribose and phosphate groups. Levene concluded that, due to an increased capacity of variance with proteins, DNA would not be the genetic material of cells.

DNA was discovered in by Swiss researcher Friedrich Miescher , who was originally trying to study the composition of lymphoid cells white blood cells. Instead, he isolated a new molecule he called nuclein DNA with associated proteins from a cell nucleus.

Deoxyribose sugar, too. Answer: Deoxyribonucleic acid — a large molecule of nucleic acid found in the nuclei, usually in the chromosomes, of living cells. DNA controls such functions as the production of protein molecules in the cell, and carries the template for reproduction of all the inherited characteristics of its particular species. Unlike bacterial chromosomes, the chromosomes of eukaryotes are linear rod-shaped , meaning that they have ends.
