Concept explainers
To suggest: The evolution of archaea, bacteria, and eukaryotes regarding the studies which showed that archaea, but not bacteria, has a protein that is functionally and structurally similar to TATA-binding protein.
Introduction: TATA-binding protein is a transcription factor that is thought to be necessary for eukaryotic transcription. This factor binds specifically to TATA box (DNA sequence), which is present 30 bp (base pair) upstream of the starting site of transcription. The branch of science that deals with the scientific study of diversity and evolutionary relationships of organisms is known as systematics.
To explain: The way in which knowledge of the similarity regarding TBP affect the classification of archaea, bacteria, and eukaryotes by systematists.
Introduction: Systematics is used to construct a cladogram that is an evolutionary tree that depicts the relationship among different species by studying the similarities or differences.

Give arguments supporting (or challenging) this hypothesis.arrow_forwardTest Your Understanding Evaluate and Synthesize 17. EVOLUTION LINK Scientists have proposed various initiatives to detect water vapor, as well as oxygen and carbondioxide, in the atmospheres of distant planets. Which of these biosignatures (chemical markers that are evidence for life) would you consider the most fundamental indicator that life could have evolved on these planets? Explain your reasoning.arrow_forwardA CRISPR locus in a bacterium contains (a) short repeated sequences (b) short DNA sequences homologous to bacteriophages (c) genes that encode guide RNAs and one or more proteins (d) a, b, and c (e) none of the precedingarrow_forward
- Test Your Understanding Know and Comprehend 1. The mold that produces penicillin is Penicillium notatum. Penicillium is the name of its (a) genus (b) order (c) family (d) species (e) specific epithetarrow_forwardEVOLUTION LINK If living cells were produced in a test tube from nonbiological components by chemical processes, would this accomplishment prove that life evolved in a similar manner billions of years ago? Explain your answer.arrow_forwardEVOLUTION LINK DNA technology, such as the production of transgenic animals, is possible only because widely different organisms have essentially identical genetic systems (DNA RNA protein). What is the evolutionary significance of the universality of genetic systems in organisms as diverse as bacteria and pigs?arrow_forward

In interpreting a cladogram, (a) we can identify the specific ancestor of each taxon by tracing each branch back to the node closest to the root (b) taxa on the right side of a cladogram have evolved from the taxa on the left side (c) the relative placement of smaller branches allows us to determine the number of years since a particular taxon has evolved (d) we can determine relationships by tracing along the branches back to the most recent common ancestor (e) we must first identify horizontal gene transferarrow_forwardTest Your Understanding 1. Which of the following is not true of the protists? (a) they are unicellular, colonial, coenocytic, or simple multicellular organisms (b) their cilia and flagella have a 9 + 2 arrangement of microtubules (c) they are prokaryotic, as bacteria and archaea are (d) some are free-living, and some are endosymbionts (e) most are aquatic and live in the ocean or in freshwater pondsarrow_forward
