Jesus A. Campos Biology 121 Section EG OUT-OF-CLASS ASSIGNMENT 4 1. This difference should result in more female zygotes being produced. 2. Pus cells. This is because the size of the cytoplasm is smaller and they have a bigger nucleus compared to other cells. 3. DNA is made up of nitrogen bases, phosphate and pentose. Clay and quartz are composed of aluminum silicate and silicon dioxide respectively, which are not elements essential for life that make up living organisms 4. The way a cell can produced the largest amount of protein in the shortest time is when the RNA polymerase molecules work together at the same time. This way the cell produces thousands of copies of the same mRNA molecule. This creates many more copies of a protein than direct protein synthesis. 5. This is because the genes contain the genetic information to make the protein. This genetic information or genetic code is triplet which permits the cell to make many different combinations for amino acids which in return gives you a wide variety of

Unformatted text preview: proteins. 6. Since the red blood cells do not have a nucleus they do not have the genetic material to synthesize new hemoglobin. After days 120 days, red blood cells die when they are destroyed by the phagocytic cells in the liver. When they are destroyed the hemoglobin is released back to the bone marrow to produce new cells. 7. Yes, because these RNA viruses integrate into the host genome, then the DNA is replicated and new cells have this new DNA. 8. DNA and RNA don’t seep into all living organisms because their cells contain restriction enzymes which cut up any viral RNA and DNA that enters the cell. 9. In order for a mammalian gene to be expressed in a bacterium it has to be accompanied by regulatory regions unique to bacteria. And the second provision is that the gene should not contain any introns because bacteria don’t have introns....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
