A DNA transcription unit is composed, from its 3' to 5' end, of an RNA-coding region (pink rectangle) flanked by a promoter region (green rectangle) and a terminator region (black rectangle).
Deoxyribonucleic acid (/ d iː ˈ ɒ k s ɪ ˌ r aɪ b oʊ nj uː ˌ k l iː ɪ k,-ˌ k l eɪ-/ ⓘ; DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix.The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.DNA and ribonucleic acid (RNA) are nucleic acids.

Hace 6 días · The configuration of the DNA molecule is highly stable, allowing it to act as a template for the replication of new DNA molecules, as well as for the production (transcription) of the related RNA (ribonucleic acid) molecule.A segment of DNA that codes for the cell’s synthesis of a specific protein is called a gene.. DNA replicates by separating into two single strands, each of which serves ...
DNA, or deoxyribonucleic acid, is the molecular basis for inheritance, discovered in the mid-1800s and understood in 1953 with the double helix structure. Composed of a sugar-phosphate backbone and base pairs (adenine-thymine, guanine-cytosine), DNA stores genetic information, replicates, and expresses traits.
DNA RNA; Definição: O DNA, ou ADN em português, é um composto orgânico cujas moléculas contêm as instruções genéticas que coordenam o desenvolvimento e funcionamento de todos os seres vivos e de alguns vírus. Os genes do DNA são expressos através das proteínas que seus nucleotídeos produzem com a ajuda do RNA.
Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions. The sequence of nitrogen bases (A, T, C, G) in DNA is what forms an organism’s traits.
