1. How does DNA encode information? DNA is a double-stranded helix composed of a phosphate backbone and deoxyribose, and encodes information by the sequence of its nucleotide bases, which are composed of adenine, thiamine, guanine and cytosine. DNA undergoes transcription, which produces single-stranded mRNA, which uses uracil in place of thiamine. Next step is translation, in which the RNA becomes a protein, which then can act as structural units or enzymes.

Nucleic acid molecules are separated when placed in a chamber with an electric field that moves the negatively charged molecules through the agarose. DNA is polar since it has a highly charged phosphate backbone, making it soluble in water. Because DNA is negatively charged, it will move towards the positively charged electrode when an electric current is applied. Shorter strands move more quickly than longer strands if gel, which is why the bands are placed in order of size on the gel.
The two base pairs are four of the small molecules that make up the DNA. The other two are the Phosphate molecule and the five carbon sugar called the deoxyribose. Nucleotides are the basic building blocks of a DNA. It is made up of one sugar molecule, one phosphate molecule and one of
helix because of the repulsion water molecules present in cells have on them. Each DNA has its proper structure because of some structures that can appear in the strand due to this high affinity between the bases. We can talk about the Harpin structures or the Cruciform structures. Harbin structures are little folds on one strand of DNA due to the bases associating with themselves and not with the opposite strand. Cruciform structures follow the same procedure but are symmetrical to both side (the 5’-> 3’ and the 3’->5’).
DNA is also found in genes. 15.disaccharide- The result of when a dehydration reaction connects two monosaccharides. 16.double helix-
Deoxyribonucleic acid (DNA) is a molecule that contains the essential genetic instructions/codes that are used in the development, functioning and reproduction of all living organisms. DNA is a nucleic acid, which, alongside proteins and carbohydrates forms the three major macromolecules that are essential for all forms of life. DNA consists of two biopolymer strands, which coil together to form a ‘double helical structure’. These two strands are known as polynucleotides as they are made up of several smaller nucleotide units. DNA consists of a linear polymer consisting of three types of molecule: an organic ‘aromatic flat base’ connected to a sugar called ‘ribose’, with an inorganic ‘phosphate linker’.
Deoxyribonucleic acid (DNA) is a molecule found in all forms of life that is passed down from parents to offspring. What makes each DNA unique is the chemical makeup of the molecule sometimes referred to as the “blueprint of life.” (BIO). DNA is made up of nucleotides consisting of a sugar, a phosphate and a base pair. About six million nucleotide base pairs make up DNA in each cell.
It is a twisting ladder, which is actually two strands that twist around each other. The strands are called polynucleotides. Polynucleotides are made out of nucleotides. Watson and another partner, Francis Crick, proved that a DNA molecule is able to duplicate itself, explains https://www.biography.com/people/james-d-watson-9525139 and https://geneed.nlm.nih.gov/topic_subtopic.php?tid=15&sid=16. Without being able to duplicate DNA molecules, organisms would not be able to grow.
On 25 April 1953, a paper appeared in Nature that was to transform the life sciences from biochemistry and agriculture, to medicine and genetics. James Watson, a young American and an Englishman, Francis Crick, then at Cambridge University proposed a double helical model for the structure of DNA (deoxyribonucleic acid) molecule. (3) Crick and Watson used model building to reveal the renowned double helix of DNA, but the X-ray crystallographic data of Rosalind Franklin ( Picture 1 on the Left) and Maurice Wilkins at King's College, London, were crucial to the discovery that allowed Watson and Crick to work out the 3D structure of DNA which was found to be a double helix.(1) After the discovery of the nuclein by Swiss biochemist Friedrich Miescher
this book mentioned many of the scientists names that involved in the momentous race that identified the double helix of DNA. the story of the book take place from 1950 to 1953 begin when Watson arrives at Cavendish laboratory in Cambridge, England, and he begins his friendships with other scientists.one of them was Francis Crick that he shared with Watson the interests in studying the structure of DNA. They went to King’s College in London to get a picture of a DNA molecule. By going to King’s College they were introduced to Maurice Wilkins and Rosalind Franklin. both of them were involved in researching DNA through crystallography in King’s College lab.
DNA is deoxyribose nucleic acid, which breaks down to a double-helix structure of sugar (deoxyribose), phosphate, and nitrogenous bases. It is an organic chemical compound found in all prokaryotes, eukaryotes, and many viruses. DNA codes genetic information, which is responsible for genetic traits and inheritance. Every living organism has its own specific set of chromosomes, which generates their genes through DNA.
The sequence of the bases provides the information, so the DNA is like the hard
In most organic molecules, a linked chain of carbon atoms bureaucracy a spine to which other atoms attach. The specific quantity and arrangement of bonds between carbon atoms creates a structurally diverse set of organic molecules in nature. those molecules may be built in immediately, branched, or ringed carbon chains and may encompass varying numbers of carbon-carbon unmarried, double, or triple
The DNA gathered by the group bore positive results only on Test for Deoxyribose; compared to the standard solution, which bore positive results on all chemical tests, namely, Test for Deoxyribose, Test for Phosphate, Test for Purines, and test for Pyrimidines.
