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:
Kelp is eaten by sea otters. Kelp is a large, brown plant that grows in the sea and is used in some foods and medicines
Explanation:
The non living things in its environment is called a " matrix,"
A matrix is what supports a non living thing to reproduce, triple its existence & reproduce in mass quantities, like soil bacteria, and others..
A group of same kind of cell is called tissue
This colored pigment is known as Hemoglobin. Hemoglobin is contained in the red blood cells of vertebrates and gives these cells their red color.
