DNA vs. Credit: Technology Networks via YouTube. Deoxyribonucleic acid DNA and ribonucleic acid RNA are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two 1. These distinctions enable the two molecules to work together and fulfil their essential roles. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

This film tells the story of the scientists and the evidence involved in one of the most important scientific quests of the 20th century: the discovery of the structure of DNA. James Watson and Francis Crick collected and interpreted key evidence to determine that DNA molecules take the shape of a twisted ladder, a double helix. The film presents the challenges, false starts, and eventual success of their chase, culminating in the classic publication in Nature on the structure of DNA. An audio descriptive version of the film is available via our media player. Franklin, Rosalind E. Watson, J. Wilkins, M. Stokes, and H.

The nucleus is a small spherical, dense body in a cell. It is often called the "control center" because it controls all the activities of the cell including cell reproduction, and heredity. How does it do this? Chromosomes, found in the nucleus, are microscopic, threadlike strands composed of the chemical DNA short for deoxyribonucleic acid. In simple terms, DNA controls the production of proteins within the cell. These proteins in turn, form the structural units of cells and control all chemical processes within the cell. Chromosomes are composed of genes. A gene is a segment of DNA that codes for a particular protein, which in turn codes for a trait.

RNA converts the genetic information contained within DNA to a format used to build proteins, and then moves it to ribosomal protein factories. Fast and accurate language certification. Patrick's Day. Z-DNA molecules are:. Science from the South. Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe. These are nitrogenous bases attached to phosphate groups and ribose sugars. DeoxyriboNucleic Acid. Write out the full name for DNA. Classroom management. More from. Credit: Technology Networks. Why can't the code be taken directly from the DNA?

The informational text will help guide students to organize and understand information about how nucleotides are joined together to create a double helix molecule. Eukaryotic cells, including all animal and plant cells, house the great majority of their DNA in the nucleus, where it exists in a tightly compressed form, called a chromosome 4.
