what term most accurately describes the shapes of a dna molecule

Answers

Answer 1

The term that most accurately describes the shape of a DNA molecule is "double helix".

What is DNA?

The phrase "double helix" is the one that most accurately describes the shape that a DNA molecule has. In 1953, James Watson and Francis Crick were the ones who first proposed that DNA has the structure of a double helix. Their theory was founded on X-ray crystallography data that Rosalind Franklin and Maurice Wilkins had obtained.

DNA has a structure known as the double helix, which is made up of two long chains of nucleotides that are twisted around each other to form a structure similar to a spiral staircase. Hydrogen bonds formed between complementary base pairs, adenine (A) and thymine (T), and cytosine (C) and guanine, are responsible for keeping the two chains connected to one another (G). The characteristics of an organism are determined by the genetic code, which is formed by the specific arrangement of these base pairs along the length of the DNA molecule.

The structure of DNA, which is a double helix, is significant because it enables the accurate duplication of genetic information during the process of cell division and provides a mechanism for the transmission of characteristics from one generation to the next.

Answer 2

The DNA molecule is most accurately described as having a double helix shape, akin to a spiral staircase, with complementary base pairs forming the steps. B-DNA is the prevalent form in biological systems.

The term that most accurately describes the shape of a DNA molecule is a double helix. This structure is similar to a spiral staircase, with the sugar and phosphate groups forming the sides or the 'backbone' of the staircase, and the nitrogenous bases (adenine, guanine, cytosine, and thymine) forming the steps. These bases pair with each other in a complementary fashion: adenine with thymine (A-T), and guanine with cytosine (G-C), enabling the double helix structure to form naturally.

B-DNA is the most common form of DNA observed in cells, characterized by a right-handed helix and 10.5 base pairs per turn. While many other forms of DNA, including A-DNA, Z-DNA, and synthetic forms exist, B-DNA is considered the most stable and predominant form in biological systems. The double helix shape is a powerful and robust structure ensuring the integrity and accurate replication of the genetic code.
