The spiral shape of dna is called a
WebDNA stands for deoxyribonucleic acid. It is a chemical made up of two long strands, arranged in a spiral. This is the double-helix structure. DNA carries genetic information - the genetic code. WebHuman cells also contain a small amount of extrachromosomal DNA located in another part of the cell called the mitochondria. This mitochondrial DNA is more like bacterial DNA—a single long, circular piece of DNA made up of two strands of DNA. A DNA strand is a long, thin molecule—averaging only about two nanometers (or two billionths of a ...

WebJun 8, 2024 · Both are nucleic acids and made out of nucleotides; however, RNA is single-stranded while DNA is double-stranded. RNA nucleotides, like those from DNA, have three parts: a 5-carbon sugar, a phosphate group, and a base. RNA contains the 5-carbon sugar ribose, whereas, in DNA, the sugar is deoxyribose.
