METACOGNITION 1 Unit 1-2
Q5 A codon… 9% ONLY GOT THIS RIGHT. 5 people had answers for B and C. Why is that a problem?
Q11. ____ are segments of eukaryotic genes that do not code for amino acids. These are removed before mRNA leaves the nucleus. 59% GOT THIS RIGHT. The clue given was “Introns Out!”. 42 people answered “exons”. 1 person answered “D”. Why is that a problem?
Q10 What is the sugar of RNA called? 60% GOT THIS RIGHT. 1 person answered “D” Why is that a problem?
Q12 Where does RNA polymerase begin transcribing? 69% GOT THIS RIGHT. 3 persons answered “B” Why is that a problem?
Converting molecules • DNA-> DNA A-T, C-G • mRNA<-> tRNA A-U, C-G • mRNA-> amino acids ( proteins) Use the genetic code.
Q1 Which statement best describes a step of DNA replication in a human cell? • Both DNA strands are copied simultaneously, One continuously in the direction that the DNA unzip. ( leading strand) And the other piece by piece in the opposite direction (lagging strand).
Q2 Which statement BEST describes the result of DNA replication? • One double-stranded molecule produces two identical double standed molecules.
Q7 Which statement best explains the process of semiconservative replication? • Two parental DNA strands separate, both acting as a template to form new complementary daughter strands.
