True, our ecosystem is not independent. Everything depends on everything else to survive. :)
Answer:
increasing extension time
Explanation:
The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.
B) Nucleus!
Prokaryotic cells do not have a nucleus, and the Nucleus in a Eukaryotic cell are large and very hard to miss (if that matters to you!)
Answer:
<h3>Velocity (Rate of change of position)</h3><h3>Velocity is a vector quantity that is defined as the rate of change of position of an object with respect to a frame of reference with respect to time. Velocity is equivalent to the speed of the object along with the direction of motion.</h3><h3>Hope this is fine for you</h3>
