The beta of the risk-free asset is zero, and the weight of the risk-free asset is one minus the weight of the share, so the b of the portfolio is: â¢ Ãp = x W(1.18) + (1 â x W)(0) = 1.18 x W â¢ So, to find the beta of the portfolio for any weight of the share, we simply multiply the weight of the share times its beta.
HESI Purpose in Perspective. Although the HESI and NCLEX exams are both nursing knowledge assessments, the primary difference is the purpose behind the tests. The HESI is a practice exam, intended on preparing nursing students to eventually take the NCLEX. While some schools may require students to take this exam, or may use the scores for evaluation proposes, the HESI is not a test that a state board of nursing uses for licensure purposes.
HaeIII is one of many restriction enzymes (endonucleases) discovered since 1970. It was the third endonuclease to be isolated from the Haemophilus aegyptius bacteria, and has a molecular weight of 37126. The enzyme's recognition siteâthe place where it cuts DNA moleculesâis the GGCC nucleotide sequence.This enzyme's gene has been sequenced and cloned.he cleavage occurs between the second and the third nucleotides (G and C). The resulting DNA fragments are known as restriction fragments. HaeIII cuts both strands of DNA in the same location, yielding restriction fragments with blunt ends.
