Viruses - Nucleic Acids Wrapped in Protein.

Friday, 6, 2020
The chapter ended with a notes and discussion on viruses.The lytic and lysogenic cycles were discussed.  The topic covered included the DNA viruses, and RNA viruses.  We also discussed some of the major recent viral epidemics.
Prions, improper folded proteins and the ramification- mad cows disease was also discussed.

The next two chapters will examine how knowledge gained from the study of viruses is being used in gene editing.

Gene Editing Used to Treat Blindness

Gene Editing used to treat blindness.
It was just reported in the news that they have used Crispr the gene editing tool inside somebody's body for the first time, in an efforts to operate on the DNA.

The procedure was done at the Casey Eye Institute at Oregon Health and Science University in Portland.

The condition is Leber Congenital amaurosis, a gene mutation that keeps the body from making a protein needed to convert light into signal to the brain.

It will take a month before it is known if the editing worked to restore vision.  If the treatment proved to be safe, and effective, doctors plan to test it on 18 children and adults.

Notes from the PowerPoint

The PowerPoint will be used to show pictures and to fill in the gaps not as yet explained. 

Translating the mRNA

You will learn how the mRNA is translated into amino acids and ultimately protein by the body.

Copy the DNA and Transcribing the mRNA

We will continue the lesson on Copying the DNA.
Then will transcribe the mRNA.

Missing pages for Chapter 10

My apologies to those of you reading through the chapter 10 packet. Don’t read beyond page 197.
I just became aware that there are three pages missing.
Those pages will be copied and given to you on Monday.

Enjoy the rest of your Sunday.
