The genetic material must be transmitted from parent to offspring c. To transmit information the genetic material must be replicated d. The genetic material must be dynamic changing rapidly in response to changes in the environment - ️️D Who discovered that DNA was the genetic material or transforming factor that could...

Griffiths (1928) mixed heat-killed 'S' bacteria with 'R' bacteria and injected a mouse with both types of bacteria. As a result, the mouse died and Griffiths obtained living 'S' bacteria from the dead mouse. How can you explain this phenomenon? -️️The DNA from the 'S' bacteria with the gene responsible for capsule formation was transferred to the 'R' bacteria when the strains were mixed. This gene transformed the 'R' bacteria into 'S' bacteria, allowing it to produce a cap...

(from the Greek, meaning cell-eating) involves the formation of an enormous membrane vesicle called a phagosome, or phagocytic vacuole, which engulfs a large particle such as a bacterium. *Only certain kinds of cells can carry out phagocytosis. - Phagocytosis 1. What is the difference between potential and kinetic energy? - -Kinetic energy is energy associated with movement, such as the movement of a baseball bat from one location to another. By comparison, potential energy is the energy th...

Biology Ch 15 Fifth Edition Brooker BRCC 1033 Exam Practice Questions and Answers Figure 15.1 A missense mutation that causes red blood cells to sickle in sickle cell disease. Scanning electron micrographs of (a) a normal red blood cell and (b) a sickled red blood cell. As shown above the micrographs, a missense mutation in the β-globin gene (which codes for a subunit of hemoglobin) changes the sixth amino acid in the β-globin polypeptide from glutamic acid (Glu) to valine (Val). (c) Thi...
