What are the two strands of a double stranded chromosome called?
The double helix.
Explain how a double helix is similar to a spiral staircase?
Two strands of DNA intertwined together and twisted to form a double helix. The sugar phosporous backbone is like the side of the stairs and the nucleotide bases are like the steps of the stairs.
What is the scientific term for the shape of the DNA strand?
The name of the shape of DNA is called double helix. There are two long strands of DNA connected in several points. These strands twist and look like a spiral or a spring.
Which best describes the structure of a DNA molecule-?
a double helix- apex
What shape is a DNA strand?
A DNA strand is shaped like a 'double helix'.
What shape do two strands of DNA form?
double helix
What is Watson and Crick's DNA model?
DNA is a double helix made of two strands linked together with hydrogen bonds.
DNA consists of two complementary strands wound together in a specific structure called a?
double helix
What is the supporting structure of the DNA double helix?
The supporting structure of the DNA double helix is called the sugar-phosphate backbone.
The structure of DNA is described as a?
Double helix - with a deoxyribose (sugar) and phosphate backbone, and nitrogenous bases in the centre.
What is the sugar phosphate supporting structure of the DNA double helix called?
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.
How many stands make up DNA double helix?
The DNA double helix contains two coiled biopolymer strands. The double helix was discovered by James Watson and Francis Crick.
