Hershey & Chase - Purpose of Each treatment in the Experimental Design - o Research question - Is the genetic material DNA or protein? o Experimental system - Virus (T2 phage) that infects bacteria (E. coli) and re-programs bacteria to make more viruses § Grow virus in a solution containing a radioactive isotope - 35S and 32P § Infect E. coli with radiolabeled virus § Remove virus from E. coli cells § Centrifuge growth solution so E. coli sinks to bottom of tube § Virus coats rema...

Compare and contrast asexual and sexual reproduction: including genetic similarity or difference between parents and offspring and among offspring. - Asexual reproduction occurs without the fusion of gametes and is usually based on mitosis. It typical results in offspring that are genetically identical to their parent. Sexual reproduction, in contrast, typically involves the fusion of haploid gametes to produce a diploid zygote and is based on meiosis. It results in offspring that are ...

Largest to Smallest - Genome > Chromosome > Chromatin > DNA > Genes > Nucleic Acid DNA Polymerase III - synthesizes new DNA only in the 5' to 3' direction Leading Strand - has one primer Lagging Strand - has multiple primers Griffith - pathogenic pneumonia cells were able to transform non-pathogenic cells Chargaff - base composition varied from species to species and A-T and C-G complementation Hershey and Chase - concluded that the genetic material of the bacteriophag...
