Imagine you are the chief biologist at NASA when Perseverance IIl returns from its mission to Earth-like exoplanet Proxima Centauri b with actual living cells. You examine the cells in a variety of ways and find that they have what look like organelles, but very different from those in Earth species. Based on their appearance, you have named them cheese hats, kidney beans, and Drake. The cells secrete a gelatinous substance that you name "PC goo" and determine that it is comprised of polysaccharides containing the monosaccharides L-xylose and L-arabinose. Curious about how these alien cells synthesize PC goo prior to secretion, you perform a Pulse-Chase experiment using radioactively-labeled L-xylose. The resulting data are plotted in the graph below. 100 cheese hats kidney beans 50 Drake --- medium (extracellular) 20 40 60 Time after chase (min.) A conclusion that may reasonably be drawn from this data is that: O PC goo is synthesized in Drake. O Cheese hats are the 2nd organelle that…
Can you identify the major theme illustrated by each of the following examples? If necessary, you may review the themes in Chapter 1 of your book Match the themes on the left with the examples on the right. Not all themes will be used. Interactions within biological systems Information flow Evolution Pathways that transform energy and matter Relationship of structure to function Reset Help Every cell contains a DNA "cookbook" that provides directions on how to make and maintain that cell When a cell reproduces, it must duplicate its DNA, providing one copy to the new offspring cell while keeping one copy for itself Wattion and Crick realized that the chemical properties of each kind of base in DNA dictated the base pairings Each base has protruding chemical groups that can best form hydrogen bonds with only one appropriate partner Besides having practical purposes, a shared genetic vocabulary also reminds us of the kinship that connects all life on Earth The process of DNA replication…
Which of the following statements about DNA are true? (choose all that apply) O It is a polymer composed of nucleic acids O It is often found as a small molecule combined with cell surface proteins and lipids and serves as a kind of name tag identifying "self" to distinguish it from "nonself" O it is a polymer composed of carbohydrates, and is one of the molecular building blocks of cell wall. O DNA is the molecule that stores the genetic information. O in eukaryotes, it is primarily found in the nucleus, a membrane-bound structure that contains the metabolic and chemical processes of gene expression and MRNA transcription. O it is a polymer composed of amino acids, and is one of the important subunits in cell membranes. O in prokaryotes, it is found in the nucleoid region, but prokaryotes don't have a membrane-bound nucleus.
