WebDec 22, 2024 · Acetylene reduction assay (ARA) is a commonly used method to detect biological N 2 fixation activities and determine the N-fixation rate of marine diazotrophs. This method was developed based on the discovery that nitrogenase, the enzyme for biological N 2-fixation processes, can also reduce acetylene (C 2 H 2) to ethylene (C 2 …

WebJul 1, 2024 · On the basis of our determined carbon fixation rates, we conservatively extrapolate global primary production in carbonate groundwaters (10% of global reserves) to be 0.11 Pg carbon per year. Fixation can refer to a gene in general or particular nucleotide position in the DNA chain . In the process of substitution, a previously non-existent allele arises by mutation and undergoes fixation by spreading through the population by random genetic drift or positive selection. See more In population genetics, fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains. … See more Additionally, research has been done into the average time it takes for a neutral mutation to become fixed. Kimura and Ohta (1969) showed that a new mutation that eventually fixes will spend an average of 4Ne generations as a polymorphism in the population. … See more • Gillespie, J.H.
