The echinoderm with long spines
belongs to the class Echinoidea which includes sea urchins, heart urchins, cake
urchins and sand dollars. This spine serves as their protective mechanism from
predators. The spines are joined to the skeleton and muscles surround it. The muscles
enable them to swivel its spines from predators.
Answer:
True
Explanation:
The Polymerase Chain reaction (PCR) is a technique widely used in molecular biology to identify specific DNA fragments generally in a size range of 100 to 1000 base pairs (bp). PCR sensitivity refers to the potential of the PCR technique to specifically amplify the desired sequence in the sample. PCR is a highly sensitive (and also specific) method with values around 100% if the experimental conditions are proper. However, to reach these values, it is imperative to work in optimal conditions by eliminating contaminant factors in the sample which may alter PCR amplification.
