cells and many viruses. It consists of two strands of nucleotides linked together in a structure resembling a ladder twisted into a spiral. In eukaryotic cells, the DNA is contained mainly in the nucleus and mitochondria. DNA can replicate itself and synthesize RNA. CompareRNA. See Note atgene...
The meaning of DNA is any of various nucleic acids that are usually the molecular basis of heredity, are constructed of a double helix held together by hydrogen bonds between purine and pyrimidine bases which project inward from two chains containing alt
DNA is used as a template to make RNA through a process called transcription. The RNA uses molecular machinery called ribosomes, which use the code to make the amino acids and join them to make polypeptides and proteins. The process of making proteins from the RNA template is called translati...
DNA definition: deoxyribonucleic acid: an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms, constructed of two nucleotide strands coiled around each other
or RNA, translates genetic information from DNA into proteins.The entire human genome contains about3 billion bases and about 20,000 genes.Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double h...

The genetic material of viruses may be single- or double-stranded DNA or RNA.Retrovirusescarry their genetic material as single-stranded RNA and produce theenzymereverse transcriptase, which can generate DNA from the RNA strand. Four-stranded DNA complexes known asG-quadruplexes have been observed ...
DNA and RNA both carry genetic information, but there are quite a few differences between them. For example, DNA's double-stranded structure provides stability and protection for genetic information, while RNA's single-stranded nature makes it more chemically reactive and prone to being broken down...
translation to occur, the DNA must first unwind and allowDNA transcriptionto take place. In transcription, the DNA is copied and an RNA version of the DNA code (RNA transcript) is produced. With the help of cellribosomesand transfer RNA, the RNA transcript undergoes translation and proteins ...
“DNA is a group of molecules that is responsible for carrying and transmitting the hereditary materials or the genetic instructions from parents to offsprings.” This is also true for viruses, as most of these entities have either RNA orDNA as their genetic material. For instance, some viruses...
