Respuesta :
The DNA double helix is made up of two strands of nucleotide monomers oriented in opposite directions.
What is DNA?
DNA typically has two strands running in opposition to one another and is shaped like a double helix. Each chain is made up of a polymer of nucleotide-based building blocks. The deoxyribose sugar molecules that make up the backbone of each strand are connected by phosphate groups.
A sugar and phosphate molecule are also joined to each base. A nucleotide is made up of a base, a sugar, and a phosphate.
Why is the anti-parallel double helix thus named?
The double helix's two DNA strands' anti-parallel orientation also aids in the molecule's twisting. DNA strands that are anti-parallel run in the opposing directions, making them strongly cling to one another.
What in biology is a double helix?
A DNA molecule's structure is referred to as a double helix. Two strands make up a DNA molecule, which spiral around one another like a twisted ladder. Each strand comprises an alternate backbone comprised of phosphate and sugar (deoxyribose) groups.
