You are given a list of seven 16S rRNA gene sequences (below) from unknown organisms. Based on the instructions below go to RDP and identify them. Then Google or go to the original publication that describe the organism to find out what each is famous for (for example "fixes nitrogen", or "produces hydrogen"). Turn in the list of genus and species names (Genus is capitalized, species is lower case- both are italicized) and what is remarkable about each. Construct a phylogenetic tree of the seven sequences. Turn in the tree and report which organisms are more closely and more distantly related. Does the genetic relatedness among the organisms correlate to their known phenotype (i. e., what they are famous for)? Discuss your answer.

You will create a molecular clock model for an arthropod gene. follow these guidelines to make your model: . your timeline will span from 90 million years ago to the present. the common ancestor in your model is an arthropod that lived 90 million years ago. the gene that you'll track codes for a protein in the species venom . the dna sequence youll track contains 10 nitrogen bases. you can choose the order of the bases and where the mutations occur. this gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. to build your model,/ calculate the estimated time period it takes for 1 base pair to mutate. the first time period will only show the common ancestor. at the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences. the first and third descendant species will survive for the rest of the timeline. the second descendant species was extinct 50 million years ago. calculate how long it will take for one full base pair mutation to occur. explain your reasoning by constructing a mathematical equation

What is genetic variation? -(a) each individual in a population has slightly different genes. -(b) some individuals in a population have more genes than others. -(c) each population of a species has slightly different genes. -(d)some populations of a species have more genes than others.

Are the brightest stars low magnitude or high magnitude?
