Document Summary
Module 2: cellular growth and signaling part 1. The cell: a quick review: be able to identify important structural elements of the cell and their function(s, describe the different stages of the cell cycle and cell division (mitosis) Origins of individual variation: gene sequence. Quantitative trait loci (qtl: epigenetic modifications. Modifications of the genetic material but not the nucleotide sequence: regulation by non-coding rna. To replicate the mechanisms by which the cell regulates the expression of genetic information: cell signaling. To follow the path by which a cell, in general terms, can respond to signals. The golgi packages and ship proteins around the cell. Ribosomes take part in protein synthesis: transform mrna into proteins. Mitochondria produce energy for the cell to function. Cilia, or microvilli, allow the cell to move and also provides more surface area to receive nutrients and signals from other cells. Energy storage in the form of glycogen. Structure such as the presence of chondroitin in cartilage.
