What is a prime factor tree? Prime Factorization: In mathematics, we can take any natural number and repeatedly break its products down to get to a unique product of primes for that number. This unique product of prime numbers is called the prime factorization of the number, and we have a...
tree for the heuristic search (using nearest neighbour interchange) was obtained automatically from a neighbour-joining tree. A discrete Gamma distribution was used to model evolutionary rate differences among sites (five categories;+Gparameter=0.9267). All ambiguous positions were removed for each ...

The maximum likelihood phylogenetic tree of selected sequences retrieved from NCBI GenBank was constructed with MEGA 7 software based on amino acid sequences. The reliability of the branches was tested using bootstrap resampling with 1000 pseudo-replicates. Structural analysis The RNA sequence (http:...
