MICROBIOLOGY FUNDAMENTALS - A CLINICAL
APPROACH - CHAPTER 8 PREMIUM EXAM
GUIDE WITH EXPERTLY ANALYSED
QUESTIONS AND 100% CORRECT ANSWERS
Chromosome ANSWER >> The tightly coiled bodies in cells that are the primary sites of
genes.
Codon ANSWER >> A specific sequence of three nucleotides in mRNA (or the sense
strand of DNA) that constitutes the genetic code for a particular amino acid.
Conjugation ANSWER >> In bacteria, the contact between donor and recipient cells
associated with the transfer of genetic material such as plasmids. Can involve special
(sex) pili. Also a form of sexual recombination in ciliated protoza.
DNA Polymerase ANSWER >> Enzyme responsible for the replication of DNA. Several
versions of the enzyme exist, each completing a unique portion of the replication
process.
F Factor ANSWER >> Donor plasmid that allows synthesis of a pilus in bacterial
conjugation. Presence of the factor is indicated by by F+, and lack of the factor is
indicated by F-.
Gel Electrophoresis ANSWER >> A laboratory technique for separating DNA fragments
according to length by employing electricity to force the DNA through a gel-like matrix
typically made of agarose. Smaller DNA fragments move more quickly through the gel,
thereby moving farther than larger fragments during the same period of time.
Gene ANSWER >> A site on a chromosome that provides information for a certain cell
function. A specific segment of DNA that contains the necessary code to make a protein
or RNA molecule.
Genome ANSWER >> The complete set of chromosomes and genes in an organism.
