Vern Whitten's Photographs Continue To Exceed Expectations -- August 31, 2016

One of the most popular posts is always the updated photograph portfolios Vern Whitten sends two or three or four times a year.

The most recent portfolio was received and posted yesterday. Already it is on the top ten list of favorite posts -- based on number of hits and "pace" of hits.

Update: a couple of hours later, now 12:57 p.m. Central Time, Vern Whitten's photographs are now #3 on the list of top 10 posts. Pretty incredible how fast his photographs move up the favorite list.

The Amazon Page

I'll get back to this article later. Perhaps. From Bloomberg Business.

Did I mention the other day that I ordered three items from Amazon on Saturday, this past weekend. I placed the order after reading a book review in The Wall Street Journal, about noon Saturday. On Sunday, Prime Shipping, the USPS brought the book to our apartment complex -- less than 24 hours later. Delivery was guaranteed to be no later than two days, Monday night by 8:00 p.m. It was at the apartment complex by noon Sunday.

Pages 892+.
It is noteworthy that CRISPR-cas9 is not mentioned in this book.

Thousands of human genes produce noncoding RNAs (ncRNAs) as their ultimate product. Examples of ncRNAs:
  • transfer RNAs (tRNAs)
  • ribosomal RNAs (rRNAs)
  • small nucleolar RNAs (snoRNAs)
  • small nuclear RNAs (snRNAs)
  • humans have both a major and a minor spliceosome
    • major: U2 snRNA-dependent spliceosome, splices most intron
    • minor: U12 snRNA-dependent spliceosome, splices a rare class of introns that often have AT/AC dinucleotides at the splice sites instead of the canonical GT/Ag splice site consensus
  • telomerase RNA
  • 7SL signal recognition particle RNA
  • a large Xist transcript implicated in X dosage compensation; enigmatic function
  • small vault RNAs found in the bizarre vault ribonucleoproten complex, which is 3x the mass of the ribosome but has unknown function
Other notes regarding ncRNAs
  • ncRNAs are very, very difficult to find using current techniques; even if the complete finished sequence of the human genome were available, discovering novel ncRNAs would still be challenging
  • BLASTN technique: used to identify genomic sequences that are homologous to known ncRNA genes
