Muddiest Point

Hey so my muddiest point is comparing/ contrasting Mitosis and Meiosis. What are the major differences?
Also, what is Independent Assortment and the Law of Segregation?

Thanks!

Hey guys, i'm having trouble remembering the different diseases and what kind of diseases they are. It would help if someone could list all of the diseases we need to memorize along with the kinds of diseases.

Hi Everyone!

I am still a little confused on autosomal dominant and autosomal recessive. How is it different from regular dominant and regular recessive. Please help. Thanks!

Hemophilia

Hemophelia is a genetic disorder in which a persons body does not have the ability to gave their blood clot.

The body of a hemophiliac does not have the ability to produce special proteins called coagulation factors. A protein necessary for the clotting of blood. The result is unstoppable bleeding.

Symptoms

-Bleeding

-Internal Bleeding

-Bleeding to death during a surgery

- Bleeding to death during serious injury

-Internal bleeding without cause

Signs

-Abnormal bleeding occurrence

-Present in family tree

Treatment

-Injecting missing clotting factor into patient

-Extra care during surgery or other important operations

hey!

what is the difference between haploid and diplod? I always get confused thanks!

Hey everyone!

So, my muddies point would probably be the pedigrees and how to figure out the different people's genotypes. I was absent on the day we learned them so if you guys could help, that'd be really great!!

Thanks!

Muddiest Point!

Hey guys, I think I pretty much get everything, but now that we've learned so many different crosses, I'm getting kind of confused as to when I use the X's and Y's and when I use ex: IaIa in problems and when I use ex: Ff or ff as answers or variables in problems.

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.

Muddies Point.

This is a question from UP page 44. Its about the blood types and one of the questions said that the person had type A blood. How do you know if the person has IaIa or Iai blood? Because they don't specify if the blood is hybrid or not....

And also on page 52 in UP I was confused on a question. Its about Huntington's disease and I know that it is a dominant allele. The question said that one of the parents was affected but I was confused on how you knew if the person had Hh or HH? The answer showed that it was Hh but how did you figure that out?

Please help me figure this out!! :)

Hey guys!

The only thing I am confused on is when they say dominant, do they mean that when there is a capital letter that that letter kind of "gets the say" and recessive doesn't because it is a smaller letter? I think I just need clarification on that and then I am good!

Well I'm confused on the pedigrees, I don't understand how you can find the genotype of a person, if you don't know their parents genotypes.

Hope you can help! Thanks!

EXTRA CREDIT!

Alright guys... 2 extra credit opportunities!

Click on this link and answer the following questions.

1. What color is the RNA backbone in this activity?

2. What 3 amino acids make up the polypeptide chain at the end of the protein synthesis activity?

First 4 people to email me the answers will get extra credit!

Opportunity #2... click on this link, enter in your FULL name... and complete the 'quiz'. You will get extra credit based on your score. This opportunity will expire on Sunday at midnight!

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!
