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. Ribosomes are a collection of proteins and small RNAs that are needed for translation.
