What is the structure and function of DNA?

What is the structure and function of DNA?

The Structure and Function of DNA as the Molecule of Inheritance. The DNA’s function is to serve as the reservoir of all the genetic information of the organism. This molecule contains genes, and one definition is that they are stretches (pieces) of the DNA molecule that code for specific functions.

What are the parts of the DNA structure?

DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

How is DNA explained?

DNA explained. Deoxyribonucleic acid (; DNA) is a molecule composed of two chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.

What is the structure of a DNA strand?

DNA structure. DNA exists as a double-stranded structure, with both strands coiled together to form the characteristic double-helix. Each single strand of DNA is a chain of four types of nucleotides. Nucleotides in DNA contain a deoxyribose sugar, a phosphate, and a nucleobase.

What is RNA pairing?

An RNA base pair forms when 2 complementary RNA bases find themselves across from one another. RNA base pairing occurs between bases in the mRNA codon and the complementary bases in the tRNA anticodon during translation (however, the base pairing rules are “relaxed” a bit, but no need to go into that now).

What is RNA transcription?

RNA transcription is the process by which some information from a gene — contained in DNA of a cell’s nucleus — is transcribed into RNA.
