Students have asked these similar questions
A. In NOT more than 200 words, explain how the double-helical structure of DNA suggests a mechanism for DNA replication?
B. In NOT more than 200 words, explain the special mechanism used to replicate chromosome ends?
Which types of chromosome mutations a. increase the amount of genetic material in a particular chromosome? b. increase the amount of genetic material in all chromosomes? c. decrease the amount of genetic material in a particular chromosome? d. change the position of DNA sequences in a single chromosome without changing the amount of genetic material? e. move DNA from one chromosome to a nonhomologous chromosome?
a. Propose three different mutations to prevent initiation, elongation, and termination of bacterial
DNA replication, respectively. Explain how/why each mutation would prevent its respective step.
(Hint: mutations can be in genes that encode proteins or regulatory DNA sequences)
b. In the early 1900s, Avery, MacLeod, and McCarty performed an experiment in bacterial cells to
determine whether DNA, RNA, or protein functions as the 'transforming molecule' (i.e. the genetic
material). In your own words, how did their experiment (depicted in the figure below) help to
answer that question?
