In Griffith's experiment shown above, a sample containing the remains of dead virulent bacteria was combined with a live non-virulent strain. The live bacteria were then injected into mice, and the mice died of infection. Choose the false statement in regard to this experiment: O This showed that bacteria can acquire genes from the environment. O This is known as transformation because a genetic trait is being moved from one organism to another. O The trait being transferred was the production of a flagella; non-pathogenic bacteria were non- motile and therefore unable to evade the mouse immune system. O This process does not occur in an intragenic manner.

Question
Choose the false statement
Choose the false statement:
O In order to provide enough diversity to meet the demands of natural selection, it is critical that
DNA polymerase make some errors creating changes in the genetic code.
O In order to preserve the instructional code for a species from one generation to the next it is
most critical that DNA polymerase work with high fidelity.
O Evolutionarily, the alterations of biological processes over time is as a result of environmental
factors altering the structure of ribonucleic acids which then produce altered proteins and
altered function that persists in the offspring of an organism.
Question 5
Choose the false statement:
O In transcription, covalent bonds are created because of RNA polymerase; some hydrogen
bonding may also occur introducing folds that generate more interesting structure like that seen
in TRNA.
O All three DNA related processes (replication, transcription and translation), rely on the particular
pairing of complementary nucleotides (or nitrogenous bases).
O For a given gene, only transcription of one of the two DNA strands will yield a meaningful MRNA
transcript.
