DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus.

Overall structure. The prim-pol domain has a mixed α/β fold that does not resemble any known DNA polymerase structure, thus defining a new DNA polymerase family ().The most prominent features of ...

Scientists have a new theory about the structure of DNA. Two strands of alternating sugar (deoxyribose) and phosphate groups make up the DNA double helix, and the strands were thought to be linked by ...

The structure of DNA made visible Date: August 31, 2015 Source: ResearchSEA Summary: From 1952, DNA was sequenced, modified and extensively studied, but no technique was able to produce clear ...

The discovery of DNA structure by James Watson and Francis Crick in the year 1953 is one of the most revolutionary scientific discoveries to date. However, the research leading to the discovery of ...

B-DNA is the most common form of DNA and has a right-handed double helix structure. A-DNA forms in a shorter, right-handed double helix. The function of this form is to protect DNA.

Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick.Created by Rosalind Franklin using a technique called X-ray ...

DNA or deoxyribonucleic acid is the basic hereditary material present in all the cells of an organism and basically provides a blue print for the cell’s functions, growth, reproduction and death.
