A double helix
A DNA strand is commonly known as a "double helix" due to its twisted shape resembling a spiral staircase.
A DNA strand is shaped like a 'double helix'.
DNA (deoxyribonucleic acid) has a double helix structure, in which two strands of nucleotides are wound around each other. This helical structure is responsible for carrying genetic information in living organisms.
DNA is called a double-helix because it consists of two strands that spiral around each other. A spiral shape is also called a helix, and there're two of them, so it's a double-helix.
The DNA double helix is unwound and each strand acts as a template for a new double helix.
In a DNA double helix, an adenine of one strand always pairs with a thymine of the complementary strand via hydrogen bonds.
No, DNA is a double-stranded molecule composed of nucleotides. Each strand has a specific sequence of four different nucleotides: adenine, thymine, cytosine, and guanine. These two strands are connected by hydrogen bonds to form the double helix structure of DNA.
A strand of DNA is shaped like a double-helix.
A DNA double helix is made up of two stands that twist around each other in a spiral shape. Each strand consists of a sequence of nucleotide bases that pair up with the bases on the opposite strand, forming the characteristic double helix structure.
