<span>Venter's contribution to science was the invention of a synthetic cell. The correct option is D. Craig Venter created a synthetic cell which is totally controlled by man-made genetic instructions. This invention has opened the door for a lot of potential new research which can be carried out in the field of molecular biology. </span>
The correct option is D.<span>
Craig Venter contributed significantly to
science and humanity by inventing a synthetic cell. He accomplished this by
constructing the genome of a bacterium and by incorporating it into a
cell. The cell was made by joining together the genome of a pathogen from small stretches of DNA that are synthesized in the laboratory. The genome created was then inserted into an empty cytoplasm of a related bacterium. The pathogen use is called mycoplasma mycoides, it usually infect goats.</span>The cell is the first synthetic life form in the world and it open the
way for new types of research.
<span>The environment has a greater amount of long nectar tubed flowers and short nectar tubed flowers causing disruptive selection in medium bill length birds.
Genetic engineering is applied to techniques like DNA cloning in which the steps are: step 1: DNA cutting from the parent source; step 2: DNA cut is pasted into the matrix to be modified; step 3: matrix is introduced to the host cell and step 4, vector DNA is isolated. Answer then is B.
