The strands of the helix align so that the nucleotides face "up" on one side of the helix and "down" on the other side of the helix. Nitrogen bases in the two strands of the helix form hydrogen bonds with each other across the width of the molecule. On the DNA molecule an adenine (A) on one strand, always bonds with thymine (T)on the opposite strand. Likewise guanine (G) always hydrogen bonds with cytosine(C)The term complimentary is always used to describe these pairings. For example, A is complementary to T and C is complementary to G. The overall appearance of the DNA molecule is very similar to a rope ladder that is twisted, with the hand rails of the ladder composed of sugar phosphate backbone and the rungs of the ladder composed of paired nitrogenous bases.

Thank you for telling us what DNA looks like. Now try to answer the question.

Nucleic acids are biological macromolecules that store and transmit genetic information. They are made up of nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. The two main types of nucleic acids are DNA and RNA.


What are the three necessary characteristics of the hereditary molecule in cells?

The three necessary characteristics of the hereditary molecule in cells are: the ability to store genetic information, the ability to replicate and transmit this information accurately during cell division, and the ability to undergo mutations that provide genetic variation for evolution.


What is the structure and function of a DNA strand molecule?

The structure of a DNA strand molecule is a double helix made up of two strands of nucleotides. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. The function of DNA is to store and transmit genetic information, which is encoded in the sequence of the nitrogenous bases along the strands. This information is used by cells to make proteins and carry out various biological processes.


What are Cells store genetic information in DNA?

Cells store genetic information in DNA, which is a molecule made up of two strands that coil around each other to form a double helix structure. DNA contains the instructions needed for the development, functioning, and reproduction of all living organisms.
