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.
A single helix molecule is a molecule that has a spiral shape resembling a single coil or spring. One common example is the DNA molecule, which consists of a single helix structure formed by its two intertwined strands.
The double helix of DNA is more stable than a single helix due to the hydrogen bonding between complementary base pairs and the structural support provided by the sugar-phosphate backbone. The double helix structure allows for efficient storage and replication of genetic information.
The two strands of a double-stranded chromosome are called chromatids. Each chromatid contains a single DNA molecule that is duplicated and bound to its sister chromatid at the centromere.
DNA is double Helix But A Gene is a part of that double helix.
The sugar-phosphate supporting structure of the DNA double helix is called the backbone. This is why the DNA is commonly referred to as a double helix.
The Double helix is actually made of repeating units called nucleotides
A Double Helix.
The twisted ladder shape of DNA is called a double helix.carbohydrate
A DNA molecule is in the shape of a double helix. It is also known as a twisted ladder or a spiral staircase. A RNA molecule is in the shape of a single helix, seeing as it is single stranded.
