When setting up a Sanger sequencing reaction, each reaction should include template DNA, nucleotides, dideoxynucleotides, buffer
kondaur [170]

Answer:

b. Forward or reverse primers

Explanation:

Sanger sequencing is a technique of DNA sequencing based on the extension of DNA fragments with variable sizes terminated with dideoxynucleotides at the 3′ end. This technique was developed by Frederick Sanger in 1977. In Sanger sequencing, a short primer is added in order to bind by complementarity to the target DNA region of interest. Subsequently, a DNA polymerase adds nucleotides (A, T, C and G) in the 5'-3' direction. Finally, the extension of the DNA strand is stopped by adding dideoxynucleotides, which are nucleotide analogs (i.e., modified nucleotides) that act as DNA synthesis terminators.

Within each year, what is the pattern of change in CO₂ concentration? Why does this pattern occur?
telo118 [61]

The pattern of change in CO₂ concentration is new plant growth in the spring increases photosynthesis rates, which lowers CO2 concentrations; this decline continues until autumn, when leaves fall and decompose, raising CO2 concentrations.

The level of carbon dioxide within the surroundings rises and falls every 12 months as plant life, thru photosynthesis and respiration, absorbs the gas in the spring and summer season, and launches it in fall and wintry weather. Now the range of that cycle is expanding as extra carbon dioxide is emitted from burning fossil fuels and different human activities.

In spring, flora in the Northern Hemisphere starts to develop and absorb CO2 from the atmosphere, so atmospheric CO2 attention decreases as the road dives down. In fall, flora starts to decay and release their CO2 again into the ecosystem, so atmospheric CO2 attention increases the line shoots up. plants are accumulating carbon within the spring and summer while they are lively, and they're liberating carbon again to the air in the fall and winter.
