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.
Answer:
All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions.
Answer:
they may "loop out" of the cell cycle and into a resting state called G0, from which they may subsequently re-enter G1 under the appropriate conditions
Explanation:
At the G1 checkpoint, cells decide whether or not to proceed with division based on factors such as: Cell size
Fertilizer can lead to algal bloom in aquatic ecosystems, which means that its usage may lead to oversaturation of algae in the seas and oceans. Although algae are good for these kinds of waters in limited amounts, when there are too much of them it can stifle all other life, thus having negative effects on aquatic ecosystems.
