The discovery of DNA has allowed us to trace ancestors and find out how early humans lived, what they looked like, and who they were.
rDNA is using genetic cloning to form DNA molecules from different species. in this example you can make the hormone insulin by getting some of the components from one organism and getting the remainder from another organism. Specifically, Insulin has 2 amine chains, so you can get 1 amine chain from one organism, and the other from a different one. Then you can combine them and you'll get insulin.
Answer:
A. Natural selection results in those individuals within a population who are best-adapted surviving and producing more offspring. The traits that promote survival are heritable.
Explanation:
Natural selection works on the genetic variations that are already present in the natural populations. Some organisms of a population are more likely to produce more offspring than the others. This is due to the presence of beneficial genetic traits in these individuals that impart survival and reproductive fitness to them. Natural selection favors those individuals. Over the generations, the frequency of the beneficial genetic trait in the population increases.
The light reactions use the reactant water from the equation and release the product oxygen.
