- All living things are divided into three domains: bacteria, archaea, and eukarya. They have several traits that are specific to each domain or shared across the domains. Based on this information, what traits would the last universal common ancestor (LUCA) be expected to have? A. Nuclear envelope, introns in genes, and peptidoglycan in cell walls. B. Histones associated with DNA, circular chromosome, and peptidoglycan in cell walls. C. Unbranched hydrocarbons in membrane lipids, histones associated with DNA, and introns in genes. D. Circular chromosome, unbranched hydrocarbons in membrane lipids, and one kind of RNA polymerase.A sample of bacteria is collected from soil in a field that was recently treated with pesticides. The bacteria are classified and a phylogenetic is built to illustrate the soil bacteria diversity. What kinds of characteristics would be best for creating this phylogenetic? a. rRNA gene sequence and amino acid sequence of lipase b. Cell wall structure and physical appearance c. Reproductive rate and susceptibility to pesticides d. Entire genome sequence and protein expression dataWhich of the following is an accurate point that supports the idea that the earliest protocells relied first on RNA (not DNA) as inherited information? A. RNA is composed of lipids, and lipids were present on early Earth before the nucleotides that compose DNA were B. RNA is a monomer (unlike DNA), so it is simpler and more likely to have been used by these simple protocells C. DNA would have been too large to fit into the small protocells, but RNA was small enough to fit D. RNA can serve dual roles as both genetic information storage and an enzyme (but DNA cannot do both) ..
