BIOM1050 Lecture 2: MODULE 1 - L2
Document Summary
Module 1 - a study of life and. Most bacterium can get bacterium can produce dna. Flagella and pili are used for motility and attachment. The nucleus contains the dna the cell"s heritable material. The interior of nucleus contains dna + protein = chromatin. Nucleolus - site where ribosome units are assembled. They read the mrna and produce the encoded protein. A membrane system continuous with the outer membrane of nucleus. The rough er harbours ribosomes, ie it is a major organelle for protein synthesis. Proteins are then chemically modified (adding sugars and/or phosphates) inside the er, then transported in the er to golgi endomembrane system. Both prokaryotes and eukaryotes free in cytoplasm and attached to endoplasmic reticulum, mitochondria and chloroplasts consist of a large and a small subunit. The mitochondria are the respiratory centres of the cell. The site of respiration (the process of harvesting energy from food molecules.
