What is the molecular structure for nucleic acids?
Nucleic acids are long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.
Why did Watson and Crick write the article molecular structure of nucleic acids?
““A Structure of Deoxyribose Nucleic Acid” had immediate impacts on both the study of DNA as genetic material and the field of molecular biology. Watson and Crick´s article shifted scientists away from the question of how DNA was structured and toward the question of how DNA functioned.
What is the purpose of this article why did Watson and Crick write this article?
This paper is short because it was intended only to announce Watson and Crick’s discovery, since they believed they were in a race. They later published a paper with more details. Do you think this discovery was worthy of a Nobel Prize?
Who published a paper in 1953 in Nature describing the structure of DNA?
Watson and Crick
When Pauling sent a paper to be published in early 1953 that proposed a three-stranded DNA structure, the head of the Cavendish gave Watson and Crick permission to work full-time on DNA’s structure.
What is nucleic acid how many types of nucleic acid are there describe the molecular structure of DNA?
two
The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base.
Which of the following structure is classified as a nucleic acid?
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria.
What did Watson and Crick both agree on about DNA?
They state that DNA is found in all cells that undergo cellular division. Watson and Crick also state that DNA carries a cell’s genes. Watson and Crick go on to say that no scientist before them had suggested a way for DNA, and thus the genes contained within it, to copy itself.
What evidence did Watson and Crick use to describe the structure of 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 crystallography, it revealed the helical shape of the DNA molecule.
What are nucleic acids describe structure of DNA Watson and Crick model?
Watson and Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix. Base-pairing takes place between a purine and pyrimidine: namely, A pairs with T, and G pairs with C.
How the structure of DNA looks like which was proposed by Watson and Crick?
In “A Structure of Deoxyribose Nucleic Acid,” Watson and Crick described DNA as a double helix that contained two long, helical strands wound together. In their model, each DNA strand contained individual units called bases, and the bases along one DNA strand matched the bases along the other DNA strand.
Who published the structure of DNA?
James Watson
The 3-dimensional double helix structure of DNA, correctly elucidated by James Watson and Francis Crick. Complementary bases are held together as a pair by hydrogen bonds.
How does the structure of nucleic acids relate to its function?
Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.
