Answer:

Option C

Explanation:

Dr. Leland Hartwell used baker’s yeast, <em>Saccharomyces cerevisiae</em>, as a model system, which was a highly suitable model for cell cycle studies. He introduced the concept of Checkpoints where he said cells are arrested if damaged so that the cells repair system can work to correct such damages. Dr. Paul Nurse used a different type of yeast, <em>Schizosaccharomyces pombe</em>, a type of yeast distantly related to the baker's yeast as a model organism.

V125BC [204]

They contain symbiotic bacteria called rhizobia within nodules in their root systems, producing nitrogen compounds that help the plant to grow and compete with other plants. When the plant dies, the fixed nitrogen is released, making it available to other plants; this helps to fertilize the soil.

xenn [34]

Answer:

The correct option is <em>A) Carry out DNA cloning of the desired sequence into a plasmid vector and then put that into bacteria and wait for the bacteria to copy the gene every time the cells divide.</em>

Explanation:

The DNA can be easily cloned by the help of vectors like plasmids. Plasmids can be described as an extra-chromosomal ring which is present in bacteria. The plasmid has many multiple cloning sites where the desired DNA can be incorporated. the plasmid with the foreign DNA is then incorporated back into a bacterial cell. As bacterial cells like E.coli divide in a short period of time, many copied of our DNA could be obtained whenever the bacterial cell replicates.
