Answer:

Primary productivity is defined as the rate of conversion of photosynthetic and chemo-synthetic energy by the autotrophs into the organic substances. It is affected by the temperature, light, availability of nutrients and some other factors. It measures photosynthetic productivity.

It is important because it forms the basis of the food web in the ecosystem. It can be measured by the rate of sugar formation, the rate of oxygen production and by the amount of carbon dioxide consumed.

Which of the following is not required for the proper use of molecular beacons?

arlik [135]

Answer:

b. Detachment of a separate hybridized probe molecule from the template DNA

Explanation:

Molecular beacons are a type of genetic probe that enables the hybridization of oligonucleotides. These molecules have a flourishing component that binds to a nucleotide sequence and allows the identification of this nucleotide sequence in DNA or RNA without the release of radioactivity. For the use of these molecular beacons to be possible, one needs complementarity between the model DNA and the probe sequence, illumination of the hybridized beacon to detect fluorescence and proximity-based quenching of the fluorophore prior to beacon hybridization.
