Early researchers experimented with nucleoplasmin and demonstrated that proteins targeted to the nucleus have a specific nuclear localization sequence.  Remembering this experiment, which of the following statements is true?   a. The core nucleoplasmin fragment ended up in the nucleus.     b. nucleoplasmin does not require a nuclear localization sequence to enter the nucleus   c. The tail nucleoplasmin fragment has the nuclear localization sequence   d. Nuceloplasmin was fragmented and the parts were injected into the same cell

What observations are consistent with the conclusion that DNA serves as the genetic material in eukaryotes? Select the four correct statements. a. DNA content and ploidy in various cell types( sperm and somatic cells) are related b. DNA is found to be the only macromolecule in eukaryotes that has different subunits. c. Gene transfer is a direct evidence as it has been facilitated by recombinant DNA techniques. d. The correlation of the action and absorption spectra of ultraviolet light support the interpretation that DNA is a genetic material. e. DNA is shown to be present in ribosomes, matrix, and nucleus, where genetic function is performed. f. DNA is shown to be present in mitochondria, chloroplasts, and nucleus, where genetic function is performed.

Which of the following proteins would you expect to be translated by a ribosome associated with the rough endoplasmic reticulum?   A. A potassium channel that localizes to the plasma membrane   B. Pyruvate kinase (a protein involved in glycolysis)   C. A component of RNA polymerase II (a.k.a. RNA Polymerase 2)   D. A component of DNA polymerase

What is the purpose of each of the following ingredients when present in an homogenization buffer for isolating organelles? a. EDTA b. PVP or PVPP c. BSA d. sucrose

Which of the following is NOT true about mitochondria and chloroplast proteins? A. Proteins of both organelles are unfolded as they are transported. B. The proteins have N-terminal signal peptides C. The proteins need a proteins translocator D. The proteins remain unfolded once they cross the membranes E. Most of the proteins are encoded by nuclear genome

which of the followimg would be found inside the nucleus of the structure shown on the diagram

Let's say that you have been tasked, at a bioengineering firm, to design a synthetic biological cell.  One of the first things that you and your team must consider is the size of the cell.  Each member of the team decides that it should not have a radius longer than 100 um.  Why do you and your team decide this?  Isn't bigger better?
