Document Summary
Lecture 1 - genomes and the flow of biological information. Genome: the complete dna sequence of an organism, which serves as its instructional blueprint. Centromere: a region of heterochromatin in each eukaryotic chromosome through which the chromosome becomes attached to the mitotic spindle, allowing daughter chromosomes to segregate correctly at each cell division: living organism must be different from their environment. Have a physical barrier to separate from environment. Allows internal of organism to regulate: able to store information in stable way. Have dna to characterize features, structure and function: must be able to replicate, extract energy from environment to its own use. Progenote: another word for last universal common ancestor (luca) Lipids: constructed from repeated subunits multiple fatty acids molecules. Dna (deoxyribonucleic acid): is a type of nucleic acids. Guanosine (g), adenosine (a), thymindine (t) and cytidine (c) Replication = separation (or segregation") of the copies. Dna polymerase: synthesizes the new dna copies.
