Nucleic Acids Nucleus Physiological Probes Answer There are two types of DNA based on location – Nuclear DNA and Mitochondrial DNA. Nuclear DNA: Nuclear DNA (nDNA), also known as autosomal DNA, is located in the nucleus of eukaryotic cells. Every cell contains two copies of nDNA. Nuc...
Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four major types of macromolecules that are required for all known forms of life, alongside proteins, lipids, and complex carbohydrates (polysaccharides). As they are made up of smaller monomeric units called ...
In this video, we’ll cover what nucleic acids are and what they’re made of. Nucleic Acid Structure Nucleic acids are what make up our genetic material. To know how and why they go together to form structures like the famed DNA double-strand helix, it helps to understand their shape ...
