BIO 181 ASU Unit 5DNA as hereditary material- Griffith - correct answer Griffith worked with two strands of Streptococcus Pneumoniae. One virulent strand and 1 non virulent strand. Results of mouse test - correct answer Found that the benign strand + the heat killed virulent strand still killed the mouse. Griffith found that heat-killed virulent S. pneumonia cells could transform a nonvirulent rough strain into a smooth virulent strain. He called this transformation Is protein, DNA, or RNA...

Who performed classic experiments that supported the semiconservative model of DNA replication? - Meselson and Stahl What separates the DNA strands during replication? - helicase A new DNA strand elongates only in the 5' to 3' direction because - DNA polymerase can only add nucleotides to the free 3' end. What is the role of DNA ligase in the elongation of the lagging strand during DNA replication? - It joins Okazaki fragments together

Genetics Module 2 Exam With Questions and Answers 100% Solved What are the four nucleotides that make up RNA? - answerAdenine, Guanine, Cytosine, Uracil What three general characteristics must the genetic material possess? - answerGenetic material must: 1. Contain complex information 2. Replicate faithfully 3. Encode the phenotype A segment of DNA from Drosophila melanogaster has the sequence: 5' TCA AGC TTA AGA AGG CAT TTT 3' (i) Assuming that this is the template strand, what is t...

GCD Quiz 6 Questions with Correct Answers The following statements below concern DNA replication. One of them is not true. Which is the false statement? A DNA double helix obeys the AT/GC rule. A DNA double helix could contain one strand that is 4 generations older than its complementary strand. A DNA double helix may contain two strands of DNA that were made at the same time. A DNA strand can serve as a template strand on many occasions. - Answer-A DNA double helix may conta...
