![]() ![]() It is a structural unit of the Chromosome.Each person has a different sequence of DNA.It has a key role in passing genetic information from one generation to the next.which contains all information related to inherited in its structure which has nitrogen bases It is a genetic material that enables transferring of information from one cell to the daughter cells.What are the Functions of DNA?īelow are the important functions of DNA: adenine with thymine with the help of hydrogen bond and cytosine with guanine with the help of hydrogen bond. The bases are further connected with each other in a pattern for ex. It is composed of four nucleobases which are cytosine, thymine, adenine and guanine which are also labelled as C,T, A and G alphabetical letters. The bases are made up of nitrogen-composed nucleobases which later are connected with each other with the help of hydrogen bonds. It can be further divided as deoxyribose which reflects the sugar compound and nucleic acid denotes base pair and phosphate bond. The DNA is a combination of repeated monomers which are known as nucleotides. They generate energy from the food consumed. Therefore, they are responsible for supplying energy to cells. The most significant cell organelles mitochondria and which is known as the powerhouse of the cell. DNA present in the nucleus of the cell is called nuclear DNA. Thus, the chromosomes consisting of DNA play a crucial role during the process of cell division. Plays a crucial role in gene controllingĭuring the study of cell structure and organelles which are known as chromosomes in the nucleus, the carrying genetic information or DNA is identified.It was discovered by Andres Wang and Alexander Rich.Its shape is like a double helix in zig- zag.Type B DNA is present under physiological situations.It helps to protect DNA in situations like desiccation.It is a type of dehydrated DNA which denotes the shape of A.Each individual consists of 2000-2500 genes. ![]() ![]() The size of human DNA is 3 meters of total length.Around 98 – 99% of humans have the same DNA.Some Interesting facts related to DNAīelow are some facts related to DNA which everyone should know DNA also carries the genetic instructions which help in the development and reproduction of several living organisms and viruses. The molecule is made up of two nucleotides which are known as Polynucleotides. These bases later combine with hydrogen bonds consisting of a backbone made of sugar-phosphate resulting in formation of DNA structure. The DNAs are responsible for the development, functioning and growth of living organisms. DNA comprises mainly four nitrogen composed bases which are Cytosine, thymine, adenine and Guanine. What is the Importance of DNA in Genetics?Īs mentioned above it stands for deoxyribonucleic acid which is a complex molecular structure found in living organisms.No commercial reproduction, distribution, display or performance rights in this work are provided. Publication Date (Web): July 1, 2005.ĭNA Electrochemistry through the Base Pairs Not the Sugar−Phosphate Backbone These results confirm that the base pair stack is the pathway for DNA-mediated charge transfer, not the sugar−phosphate backbone. While the introduction of one or even two nicks in the sugar−phosphate backbone yields no detectable effect on electron transfer, a CA mismatch significantly attenuates the electron transfer yield. Using intercalated, covalently bound daunomycin as a redox probe, ground state charge transport in DNA films with a perturbation in base pair stacking was examined in comparison with breaks in the sugar−phosphate backbone. ![]()
