  1. S. cerevisiae has 16 chromosomes that contain the sequences of ~6000 genes. If an investigator wanted to obtain the complete sequences for all S. cerevisiae genes from NCBI, what is
    the minimum number of records that he/should could obtain that would contain all the information?

    What common feature would be found in all of the accession numbers?

  2. How do the S. cerevisiae transcript sequences in NM_______ records differ from the actual sequences of mRNAs?
  3. Each S. cerevisiae gene has a locus name, which is based on its chromosomal location. The fig- ure below shows the positions of yeast ORFs (A-E), which are located on chromosomes I-III. Beside each pair of locus names, write the letter that corresponds to its chromosomal location.
  4. The light chain of cytoplasmic dynein, a microtubule motor protein, is encoded by the S. cerevisiae DYN2 gene. Find the chromosome record with the DYN2 gene at NCBI.

    What is the locus tag (systematic name) for the gene?

    Unlike most S. cerevisiae genes, the DYN2 gene contains introns. (You may want to open the DYN2 record in the SGD and consult the Chromosomal location field for a graphical view.) What is the total length of the transcript in base pairs?

    How many exons are present in the gene?
    How long are the exons (bp)?
    How many amino acids are found in the Dyn2 protein?


How well do you think you know science, history and geography? Test yourself

Quick show of hands. How much do you remember from your high school classes? Even if it’s been decades since you last attended, some lessons like civics and home economics can linger throughout the years. Others, like history, math and science … maybe not so much.

It’s understandable, though. Hard facts and specific dates are tricky to memorize. And unless you’re applying this knowledge to your life, you probably don’t think about it. Tap or click to see how well you know U.S. geography.

But if you pride yourself as a trivia champ or a Jeopardy whiz, then this stumper of a quiz will be the perfect challenge for you. It covers subjects ranging from science to history, and it even stumped several of our writers here at Komando.com. Think you have the smarts to get all the answers right?
