WebCan a replicase be found in the vast sequence space by random drift? We partially answer this question through a proof-of-concept study of the times of occurrence (hitting times) of some critical events in the origins of life for low-dimensional RNA sequences using a mathematical model and stochastic simulation studies from Python software. We … WebThe lowest common ancestor (LCA) of two nodes x and y in a binary tree is the lowest (i.e., deepest) node that has both x and y as descendants, where each node can be a descendant of itself (so if x is reachable from w, w is the LCA). In other words, the LCA of x and y is the shared ancestor of x and y that is located farthest from the root. in the rockies with kit carson
