Phage lambda must first attach to the host cell surface and insert bacteriophage DNA by contracting the sheath proteins. Upon entering the host cell, the linear double-stranded phage DNA is circularized to prepare for capsid protein synthesis. Next, the phage replicates the DNA genome and packages the DNA into capsids. Finally, the phage lyses the host cell and progeny phagesare released. A. occurs at random leading to the prevention of some key steps in the viral replication cycle. B. allows host cells to remember infection by copying small sections of viral DNA into RNA. C. destroys the infected cells and halts viral production. D. recognizes viral mRNA and prevents further viral gene expression.

Prior to the development of dna fingerprinting, blood type could be used to determine possible parentage. although it might prove someone was not a parent, it could not show if someone was positively the parent, only that he or she might be a parent. which of the following is a true statement that can be made about parentage based on blood typing?

If a strand of dna has 35% thymine. what is the percentage of cytosine, adenine, guanine?

Me plz he did not infringe upon the policy making powers that he felt the constitution gave congress. but the determination of foreign policy became preponderantly a presidential concern. when the french revolution led to a major war between france and england, washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-british. rather, he insisted upon a neutral course until the united states could grow stronger. which provides the best objective summary of this excerpt? president washington made a good choice when he decided not to accept the recommendations of his advisors and instead insisted that the united states stay neutral during the war between france and england as president, washington believed that the united states should remain neutral in foreign policy even though he had advisors who recommended that he take sides during the war between france and england. washington did not make policy decisions during his presidency because he did not want to interfere with the policy-making powers that the constitution gave congress. washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-britis
