ANTA01H3 Chapter Notes - Chapter 3: Body Plan, Mitosis, Microevolution
Document Summary
Genetics the study of gene structure and action and the pattern of transmission of traits from parent to offspring. Genetic mechanisms are the foundation for evolutionary change. Nucleus a structure (organelle) found in all eukaryotic cells. Deoxyribonucleic acid (dna) the double-stranded molecule that contains the genetic code. Ribonucleic acid (rna) a molecule similar to structure in dna. Three different single- stranded forms of rna are essential to protein synthesis. Cytoplasm the portion of the cell contained within the cell membrane, excluding the nucleus. The cytoplasm consists of semi-fluid material and contains numerous structures involved in cell function. Proteins three-dimensional molecules that serve a wide variety of functions through their ability to bind to other molecules. Protein synthesis the assembly of chains of amino acids into functional protein molecules. Somatic cells basically, all the cells in the body except those involved with reproduction. Gametes reproductive cells (eggs and sperm in animals) developed from precursor in cells in ovaries and testes.
