Math Easy Solutions | Organic Compounds: Nucleotides, DNA, RNA, ATP @mes | Uploaded May 2024 | Updated October 2024, 4 hours ago.
In this video I provide an overview of the essential molecules found in all life forms on Earth, namely the nucleic acids DNA and RNA as well as their precursor and "energy currency" ATP. The terms covered and their definitions are listed in the timestamps.

- Diagram of RNA and DNA: 16:51
- Deoxyribonucleic acid (DNA) is composed of 2 polynucleotide chains in a double helix: 18:01
- 98% of DNA in humans are non-coding (aren't patterns for protein sequences): 18:31
- Structure of the DNA double helix: 18:45
- Location of eukaryote nuclear DNA: 20:34
- Ribonucleic acid (RNA) is typically made of 1 polynucleotide chain: 22:00
- Hairpin loop of RNA folded onto itself: 22:47
- Nucleic acid sequence is a succession of bases indicating the order of nucleotides: 23:28
- Sequences usually presented form 5' end to 3' end: 24:21
- DNA and RNA are synthesized in the 5' to 3' direction: 25:25
- Polymerase is an enzyme that synthesizes long chains of polymers or nucleic acids: 26:24
- Enzymes are proteins that accelerate chemical reactions: 26:28
- Phosphodiester bond is when two hydroxyl groups in phosphoric acid react with hydroxyl groups on other molecules to form 2 ester bonds: 27:15
- Diagram of phosphodiester bonds between 3 nucleotides: 29:09
- Structural elements of 3 nucleotides: 30:30
- Glycosidic bond is a covalent bond that joins a sugar molecule to another group: 32:45
- Phosphate-deoxyribose backbone DNA segment shown from 5' to 3' end: 33:21
- DNA sequence is written form the 5' to 3' end for the Top strand and 3' to 5' for bottom strand: 34:48
- Corresponding RNA sequence with U replacing T: 35:32
- Adenosine triphosphate (ATP) or "molecular unit of currency" provides energy to many cellular processes: 36:05
- ATP is a precursor to DNA and RNA, and used as a coenzyme: 37:59
- Structure of ATP, ADP, and AMP: 38:59
- Hydrotrope solubilizes hydrophobic compounds without micellar solubilization: 39:47
- Micellar solubilization creates a colloidal mixture via surfactants aggregates termed micelles: 40:33
- Hydrotropes consist of a hydrophilic part and a smaller (than for surfactants) hydrophobic part and doesn't cause spontaneous self-aggregation: 42:29
