Document Summary
Molecular biology lecture 1, textbook pg 1-14, 93-97. Prokaryotic cells: eubactieria and archaea, cincle-celled, lack nucleus and organelles, in some ways may resemble eukaryotic cells more than eubacteria, about 1 micrometer. Eukaryotic cells: plants, fungi, animals, humans, single-celled or multicellular, have nuclei and organelles, about 5 micrometers. All known life forms possess a genome. Encodes the information to construct and maintain an organism. Most genomes are made of dna: some viruses have rna genomes as viruses are not classified as alive. Release of the biological information stored in the genome requires genome expression. Transcriptome: the first product of genome expression: maintained by the process of transcription (rna synthesis; i. e. , dna to. Proteome: the second product of gene expression: collection of proteins in a cell; defines the biochemical functions of a cell, maintained by the process of translation (protein synthesis; i. e. , rna to protein formed by amino acids) Genome (dna) -> transcriptome (rna) -> proteome (protein)
