ee... As buds give rise by growth to fresh buds, and these if vigorous, branch out and overtop on all sides many a feebler branch, so by generation I believe it has been with the great Tree of Life, which fills with its dead and broken branches the crust of the earth, and covers the surface with its ever branching and beautiful ramifications."

The full statement is this: In 1859, Charles Darwin wrote, 'The ........................... ...... At the based of the evolutionary tree of all life is AN ORGANISM THAT IS A COMMON ANCESTOR TO ALL LIVING ORGANISMS.

In biology, evolution has to do with gradual but constant changes in the overall form of living organism. Scientists believe that all life forms came from a common ancestor; it is through the process of evolution and natural selection that primitive life forms developed into higher forms of living organisms. In short, what the statement given in the question is trying to say is that ALL LIVING ORGANISMS ARE RELATED BECAUSE THEY HAVE A COMMON ROOT (A COMMON ANCESTOR).

Describe at least two other experiments that could be done to verify that chromosomal gene editing occurred in the bacteria.
brilliants [131]

The two ways by which we can detect that gene editing have occurred in the bacteria are;

A) WESTERN BLOT; Here,the gene that is edited will not be able to synthesize the protein.With this,if we do western against the already edited protein,no band will eventually appear in the western blot,and this indicates/confers that the gene have been edited.

B) PCR FOLLOWED BY SEQUENCING; IN PCR,there is amplification of the region with the use of flanking end primers that is edited.

However,mean primers will actually be used in a way that one primer is upstream to site of editing and the other primer to the downstream.

From this stage,the PCR product that is amplified will be sent for sequencing,and this sequency result will further confirm if the gene has been edited or not edited.

Restriction enzyme can also be used if the place where the gene has been edited is known.

If actually the gene has been edited,the nucleotide sequence will get changed.Having to choose such enzyme that cut only one's wide type wild type DNA but not actually gene that is edited,the result will further be compared inorder to confirm whether the gene has been edited or not.
