Genetic disorders


Hello bio class!

Today I will explain the basics of Patau's syndrome, or Trisomy13. Trisomy 13 is a more specific explanation of the disorder. It literally is a third copy of the 13th chromosome in the human genome. This can cause overlapping of eyes, hands and other body parts, and other defects, and overall missing characteristics of the human structure. Most signs are visable at birth, such as the preceding symptoms, and various heart problems. The treatment depends on the symptoms. When the parents don't have the disease, the odds of a kid having it if their parents don't are about 1 in ten thousand. On average the life expectancy is less then a year, but again, it depends on the symptoms.

Hello bio period 2!

Today in biology class we checked in 13.4 notes and got a stamp.
Then Mrs. Stein introduced us to mRNA and tRNA, and showed us
how to convert a strand of DNA into a strand of mRNA. Simple right?
G pairs with C and A pairs with T? ERROR! We also learned today that
there is no (T)thymine in RNA. The substitute for T in RNA is U; Uracil.
We converted the DNA strands into RNA with this new information. Your
assignment, should you choose to accept it... is the Tribune article
that is due Monday the 21st. Don't forget to study for the test on
Monday and also the 13.1 and 13.2 flow map is due tomorrow.

This message will self destruct in 30 seconds...

Sam Carter will be the next scribe!

Muddiest point

I just found information that is confusing me. I learned that plants can get diseases (mold, fungal infections) as well, does this mean they have an immune system? How does it work? Plants don't have blood cells. The bacteria that eat the plant cells, would that make them primary consumers? What is the plant's primary line of defense? They can't sneeze.

today's homework

I know some of the homework for today is to read 35.4 in the textbook, but what notes do we take with it?

scribe 10/31/2011

Hola clase de Biologia!
En clase dos con Mrs. Stein, hay muchas actividades. Primero, todos de los estudiantes vuelven los correciones de el concurso y UP 13-18. En clase los estudiantes miran los bandejas con los bacterias y escribir la informacion por los preguntas en UP 13-18. Despues los estudianted escriben el informacion por la enfermedad por el dia. El tarea es leer el capitulo 35.2 en el libro de text, el vencimiento es meircoles.
Hi bio class!
Today in biology class period 2 we did a lot. First everybody turned in the quiz corrections and reviewed the unit packed page 13-18. Then we looked at our trays with the bacteria we gathered on friday and put in a sealed tray to grow over the weekend. Using the information we got from the lab we further completed the unit packet page 13-18. The homework is to read and take notes on chapter 35.2 in the biology textbook. It's due on Wednesday.

Reply to Sydney's question

I am sorry that I CANNOT REPLY to your blog entry. My account says that I "do not have access to this page" I want to help with your question anyway so here it goes!

ADP is Adosine Diphosphate. When it enters the cell it goes to the mitochondria to convert it into the ATP Adosine triphosphate. It does this by having it react with other chimacals that break the bond it has. When this happens an extra phosphate atom is taken from another ADP molecule and makes ATP. ADP has properties that allow it to store energy but not release it. When the bond is broken the energy is useable, and is put the form of ATP which can let the energy be used. It is then sent by the E.R. to different parts of the cell that then use that energy to preform the function of the cirtain part of the cell.

Problem?

Yes, I am having a problem determining the cell phase when they are at a point where they look like they are inbetween 2 phases.
