The function of the DNA-PK protein complex in non-homologous end joining (NHEJ) includes _____. 

For retrovirus in tumor development, how does Avian Leukemia Virus (ALV) transform cells?

In Meselson and Stahl’s experiments, bacteria were grown in a medium containing “heavy” nitrogen (15N) and then transferred them to a medium containing 14N for two rounds of replication.  After the DNA is isolated and centrifuged to separate by weight, which of the figures to the right would be expected if the DNA is replicated by a semiconservative mechanism?

ALK is a transmembrane receptor tyrosine kinase (RTK). Normal expression of ALK is restricted to the brain and nervous system. In about one third of human large-cell lymphomas, a t(2;5)(p23;q35) chromosomal translocation causes fusion of ALK to nucleophosmin (NPM) that is ubiquitously expressed, generating a novel NPM-ALK fusion protein. The NPM-ALK fusion protein consists of the first 117 amino acids of the NPM protein (this part is known to be involved in protein dimerization/oligomerization), and the intracellular part of ALK. Which of the following statements is NOT true?

Which of the following statements regarding DNA helicase activity is false?
