What is a Transforming Infection? - Virus that alters cell DNA, leading to cancer What is a lysogenic infection? - Phage DNA is incorporated into host genome and is passed on to subsequent generations What is a Lytic Bacteriophage Infection? - Host cell gets so packed with viruses that is lyses (splits) open and releases mature virions

The growth of viruses in a culture is described as a one- step curve, because - Answer virion numbers show no increase during intracellular replication and can only be counted after the virions burst from the host cell A virus that kills its host is said to be - Answer lytic Bacteriophage have a ______ complex structure than animal viruses, because ______. - Answer More/ the bacteriophage must penetrate the peptidoglycan cell wall

3 transfers of DNA - Transformation: bacteria takes up naked DNA Transduction: a virus transfers the genes Conjugation: a hollow tube, or pilus transfers genes between organisms A population has 700 individuals, 85 of genotype AA, 320 of genotype Aa, and 295 of genotype aa. What are the allele frequencies of A (p) and a (q)? A. p = 0.58, q = 0.42 B. p = 0.35, q = 0.65 C. p = 0.65, q = 0.35 D. p = 0.50, q = 0.50 - Total number of alleles = 700 x 2 = 1400 p = ((85x2)+320)/1400 = 0.35 q ...
