CH. 12 Within a group of mutants with the saem growth requirement(i.e. the same overt pheotype), mapping studies determined that individual mutations were on different chromosomes. This indicates different genes can govern different individual steps in the same biological pathway. The rates of DNA mutations are different in different organisms. Genes code for Enzymes, polypeptides, and RNA. How does RNA differ from DNA? RNA contains uracil instead of thymine and it usually is single-stranded. Which of the following statements about the flow of genetic info is true? DNA encodes info that is translated into RNA, and RNA encodes info that is translated into proteins. RNA polymerase uses the 3’ to 5’ DNA templates to synethesize a 5’ to 3’ mRNA. Which of the following molecules transfers info from the nucleus to the cytoplasm? mRNA Which of the following molecules transfers info from one generation to the next? DNA A sequence of three RNA bases can function as a codon and anticodon.

    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.
