B. genome size is correlated with the complexity of an organism: more complex organisms typically have larger genomes and less complex organisms typically have smaller genomes

   
C. genome size is correlated with the complexity of an organism: more complex organisms typically have smaller genomes and less complex organisms typically have larger genomes

A. transposase; retrotransposon
   B. reverse transcriptase; different DNA transposon
   C. reverse transcriptase; retrotransposon
D. transposase; different DNA transposon


Q3) The figure below illustrates mispairing that can arise when DNA is treated with EMS. Which of the following represents the specific mutation that would result?REC.Slide4.jpg

  
TA > CG

   
AT > TA

   
TA > GC

   
GC > CG

Answer 1

Q1. That the C - value paradox was best described by C option, which indicates that the genome size is correlated with the complexity of an organism: more complex organisms typically have smaller genomes and less complex organisms typically have larger genomes.

Q2. For nonautonomous DNA transposons to be mobile, they require a functional transposase enzyme encoded by a retrotransposon.

Q3. The specific mutation that would result from the treatment of DNA with EMS was TA > GC
