The Significance of Bacteria in the Ecology - Research Paper Example

The Significance of Bacteria in the Ecology 1. What is biology ? Biology is the study of life. 2. What are characteristics of all living things ? Living things portray the following characteristics: They are made up of cells, they reproduce offsprings similar to themselves, they sense and respond to stimuli,they die and decay or decompose, they maintain homeostasis, they undergo evolution, and they heal. 3. What are subunits of a protein, of a complex carbohydrates, of a lipid, and of DNA ? Protein is polymer made up of subunits amino acids, complex carbohydrates are composed of subunits sugars, lipids are made up of fatty acids and glycerol, and DNA is a polymer of subunits nucleotides. 4. How is hereditary information passed from one generation to the next ? Hereditary information is harbored in the DNA which can be passed from parent to offspring through reproduction thus through the entirety of a generation. 5. What is transcription and translation ? Transcription is the process of duplicating a DNA sequence into a complementary RNA copy which is eventually translated into a protein. Translation is the third step in the process of protein synthesis where the information encoded on the mRNA from the DNA is decoded by ribosome to make a given amino acid sequence which can be folded into an lively protein. 6. What is the composition and function of the cell membrane ? Cell membrane is composed of lipids (phospholipiids ) such as cholesterol, proteins and lipids or protein carbohydrates associations.The function of cell membrane is to regulate the materials which enters and leaves the cell. 7. What is the size relationship between atoms, molecules, virus particles and prokaryotic and eukaryotic cells ? The size relationship in increasing order is atoms < molecules < virus particles Read More
