Which of the following is not a criterion for an organism's genetic material? a. The genetic material must contain information necessary to construct a hole organism b. 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...

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...

Biology Ch 5-8 Fifth edition Brooker BRCC 1033 Exam Practice Questions and Answers Describe the chemical composition of biological membranes? - ANSWER-Biological membranes are bilayers of phospholipids with associated proteins and carbohydrates. What can never be energetically favorable in a biological membrane and therefore will not occur spontaneously? - ANSWER-the flip-flop of phospholipids to the opposite leaflet Let's suppose an insect, which doesn't maintain a constant body tem...
