Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell‚ it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein

Unit 3 Lecture Study Guide 1. List the 4 primary tissue types and give the general characteristics and functions of each one. a. Epithelium - 1) It protects us from the outside world – skin. 2) Absorbs – stomach and intestinal lining (gut). 3) Filters – the kidney. 4) Secretes – forms glands. Characteristics (Traits): 1) Closely attached to each other forming a protective barrier. 2) Always has one free (apical) surface open to outside the body or inside (cavity) an

What can DNA do for me? You might already be familiar with how DNA testing can help solve crimes‚ confirm the paternity of children‚ and even determine the identity of ancient mummies. Now DNA can also help you with your genealogical research. It’s a simple and painless process to gather your DNA sample and within a few weeks have results that you can. Genetics concerns the process of trait inheritance from parents to offspring‚ including the molecular structure and function of genes‚ gene behavior

Receptor Protein Protein that binds to a specific single molecule‚ enabling the cell to respond to the signal molecule. i.e. The muscles of a person exercising can not contract without receptor proteins and signal molecules that tell the muscles when to contract and when to relax. Second Messenger Signal molecule produced in response to the binding of a chemical signal. Acts as a signal molecule in the cytoplasm. Signal Molecule Carries information throughout the body and to other

1. Outline the Steps of DNA: a. DNA Replication begins at the Origin of Replication b. Helicase cuts hydrogen bonds and separates DNA in half c. Semiconservative replication produces two copies that each contained one of the original strands and one entirely new strand. d. Topoisomerases catalyze and guide the unknotting of DNA e. Single Strand Binding Proteins attach to the halves and keep the DNA molecules separated (they are needed because the sides are attracted to each other and with out

Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy.[1] Modern biology is a vast and eclectic field‚ composed of many branches and subdisciplines. However‚ despite the broad scope of biology‚ there are certain general and unifying concepts within it which govern all study and research‚ consolidating it into single‚ coherent field. Biology generally recognizes the cell as the basic unit
