Who discovered the structure of DNA and what is that structure?
James Dewey Watson discovered it, and its shape is a double helix.

What role does the deoxyribose sugar play in the structure of DNA?
The deoxyribose sugar in DNA serves as the backbone of the DNA molecule, connecting the nucleotide bases together. It provides stability and structure to the double helix shape of DNA.
Who discovered the microtubule?
Microtubules were first discovered by the cell biologist Keith R. Porter in 1945 as he was investigating the structure of cells using electron microscopy. They play a crucial role in cell shape, structure, division, and intracellular transport.
What is the basic unit of a culture social structure?
The basic unit of a culture's social structure is typically the family. Families provide a foundation for socialization, relationships, and support within a community. They also often shape norms, values, and behaviors that are then reflected in the broader society.
Who discovered the structure and function of the eye?
The structure and function of the eye were not discovered by one single individual, but rather through the work of many scientists and researchers over centuries. Contributions from figures like Alhazen, Johannes Kepler, and Marcello Malpighi helped shape our understanding of how the eye works and its anatomical structure.
What did Watson and crick call the three dimensional shape of DNA?
Watson and Crick called the three-dimensional shape of DNA a double helix. They discovered the structure of DNA in 1953.
In which year was DNA discovered?
DNA was discovered by a Swiss scientist, Friedrich Miescher, in 1869.In 1953 James Watson and Francis Crick proposed the double-helix structure for the molecule, and by 1966 the genetic code (i.e. which amino acids were coded for by which sequences of DNA bases, and what the remaining codons "meant", ) had been completely worked out.__________________________________________________________________________While examining the DNA molecule, Watson and Crick (1953), proposed a satisfactory model for the arrangement of these constituents. For this important contribution to science they were given the 1962 Nobel Prize. They hypothesized from X-ray analysis of the molecule that DNA consists of two strands, twisted in a spiral (or helix) shape. This shape resembles a twisted ladder with rungs between the two uprights. The "uprights" of this ladder are made entirely of alternating phosphate and sugar molecules. The rungs are composed only of the nitrogen bases, which are attached to the sugar. The phosphate-sugar-base is called a nucleotide. The base of the nucleotide from one "upright" of the ladder is paired with and bonded to the base of the nucleotide from the other side of the ladder, completing the rung between the two uprights. A nucleotide having adenine is always cross-paired with thymine, and one with cytosine is always bonded to guanine.
Watson and crick built models that demonstrated what?
In1953 scientist Watson and crick discovered that the structure of DNA forms the shape of a double helix ladder.
A normal structure of red blood cell?
The basic structure of red blood cells is that they have a bi-concave shape to increase surface area, and lack a nucleus so that more haemoglobin can be packed in.
How does DNA form a double helix structure?
DNA forms a double helix structure through the pairing of complementary nucleotide bases. Adenine pairs with thymine, and guanine pairs with cytosine, creating a stable and twisted ladder-like structure. This pairing is held together by hydrogen bonds, resulting in the iconic double helix shape of DNA.
Who discovered DNAs shape?
The discovery of DNA's double helix structure was made by James Watson and Francis Crick in 1953. They were awarded the Nobel Prize in Physiology or Medicine in 1962 for their groundbreaking discovery.
