In 1944, the age of molecular genetics was born when... - ANSWER- Avery, McCarthy and McCloud showed that DNA was the material that determined the genetic difference between smooth and rough pneumococci. What is the hallmark of the science of molecular genetics? - ANSWER- The isolation and use of mutant microorganisms carrying stable, heritable variations from the normal or wild-type strain. What was the basic approach used to deduce biochemical synthetic pathways? - ANSWER- To isolate mut...

Forward genetic analysis starts with... CORRECT ANSWER ...a genetic screen that identifies specific phenotypic abnormalities in a population of organisms that have been mutagenized-mutagenesis being the intentional introduction of mutation into the genome of an organism Reverse genetics approaches begin... CORRECT ANSWER ...with a gene sequence and seek to identify the corresponding mutant phenotype Saturation mutagenesis CORRECT ANSWER Mutagenesis aimed at identifying multiple mutant alle...

Key terms and concepts Biology 205 - Genetics Anticodon - answerA specialized base triplet at one end of a tRNA molecule that recognizes a particular complementary codon on an mRNA molecule. Bioinformatics - answerComputational information systems and analytical methods applied to biological problems such as genomic analysis.

Fitness and mutation; correct answers -Most mutants are deleterious -Distribution of fitness effects -Mutation and adaptation -Start with single mutation set up many lines, minimize effects of selection then see how mutation accumulates -Tail relative to ancestral type you get an increase in fitness, most are neutral and deleterious Cat Gloves example correct answers -white gloves on certain breeds like Burman due to single changes in the kit gene -At specific location of Kit gene: two...

one gene-one enzyme hypothesis - each gene contains the information needed to make an enzyme What did George Beadle and Edward Tatum research? - Relationship between genes and proteins using the Neurospora Crassa One gene-one enzyme hypothosis (Neuroposa Example) - Neurospora can grow well on minimal medium (simple sugar, vitamins, inorganic salts), and therefore it must have enzymes produced by a certain gene that that transform these materials into amino acids and vitamins needed for gro...
