The phages T4 (lytic) and lambda (temperate) share all of the following characteristics EXCEPT: A. causing productive infections that involve host cell lysis. B. existing as a prophage. C. having a DNA genome. D. Attaching via a receptor on the bacterial cell surface. E. injecting their genome into the host cell. F. having a nucleocapsid.

In the lysogenic cycle of bacteriophage $\lambda$ $a$ a repressor, cI, blocks the lytic cycle. $b$. the bacteriophage carries DNA between bacterial cells. $c .$ both early and late phage genes are transcribed. $d$. the viral genome is made into RNA, which stays in the host cell. $e .$ many new viruses are made immediately, regardless of host health.
Scientists have discovered how to put together a bacteriophage with the protein coat of phage $\mathrm{T} 2$ and the DNA of phage lambda. If this composite phage were allowed to infect a bacterium, the phages produced in the host cell would have ____________________________ (Explain your answer) a the protein of T2 and the DNA of lambda b. the protein of lambda and the DNA of T2 c. the protein and DNA of T2 d. the protein and DNA of lambda
All phages must have the ability to 1. have their nucleic acid enter the host cell. 2. kill the host cell 3. multiply in the absence of living bacteria 4. lyse the host cell. 5. have their nucleic acid replicate in the host cell a) 1,2 b) 2,3 c) 3,4 d) 4,5 e) 1,5
