Dna double helix properties
Jan 10, 2010 DNA Properties. 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 cells functions, growth, reproduction and death. The structure of the DNA called the doublestranded helical structure was first described by Watson and Crick in 1953.A distinct group of DNAbinding proteins is the DNAbinding proteins that specifically bind singlestranded DNA. In humans, replication protein A is the bestunderstood member of this family and is used in processes where the double helix is separated, including dna double helix properties
Nucleic acid double helix. The double helix structure of DNA contains a major groove and minor groove. In BDNA the major groove is wider than the minor groove. Given the difference in widths of the major groove and minor groove, many proteins which bind to BDNA do so through the wider major groove.
DNA is made of two helical chains coiled around the same axis, to form a righthanded double helix. 2. The two chains in the helix are antiparallel to each other, i. e. , the 5end of one polynucleotide chain and the 3end of the other polynucleotide chain is on the same side and close together. Properties of DNA. very stable at room temperatures because the hydrogen and hydrophobic bonds between the stacked bases hold the two polynucleotide chains together, if a solution of DNA is heated to a critical temperature, these bonds are broken and the two polynucleotide strands separate by a process called denaturation.dna double helix properties DNA replication is the biological process by which a doublestranded DNA helix is copied, producing two identical replicas. The double helix structure is key to the process of DNA replication and is the basis of the most famous quote from the original paper by Watson and Crick describing the double helix
