DNA (video) | Gene expression and regulation | Khan Academy
DNA, or deoxyribonucleic acid, is the molecule that codes for life. Chromosomes are thin thread-like structures made up of DNA. DNA is put together with some proteins into many separate …
DNA (video) | Structure of DNA and RNA | Khan Academy
Composed of a sugar-phosphate backbone and base pairs (adenine-thymine, guanine-cytosine), DNA stores genetic information, replicates, and expresses traits. The human genome contains …
Introduction to nucleic acids and nucleotides - Khan Academy
DNA and RNA, composed of nucleotide building blocks, store hereditary information. These polymers have a backbone of alternating ribose and phosphate groups, with nitrogenous …
Molecular structure of RNA (video) | Khan Academy
DNA and RNA have different sugar backbones: deoxyribose for DNA and ribose for RNA. Notably, RNA has uracil instead of thymine as a nitrogenous base.
