Is it insane to kill 97% of disease resistent crop varieties & make people eat untested genetic altered food?


The future of food video is about corporate greed that makes the USA vulnerable to food shortages, disease, and through suicidal genetics, crops will not produce seed that will grow for more than one generation. Corporations want farmers to buy seeds every year and have sued farmers for having genetically engineered seeds on their farms that corporations put there through wreckless abandonment of their moral obligation to the farmers they steal from and sue to death through legal butchery. All I'm waiting for is for the greenhouse gases to alter the climate so none of the current seeds will be able to grow. Genetic soya has poor root systems that cannot tolerate arrid conditions very well. The domino effect has been set up. All it takes is a change in climate to bring about mass starvation in the USA from the 2% of the population that grow food. Sounds like insane technology to me.

thats a lot of bull, there are seed companies that store oldfashioned varieties and disease resistant plants are what most places raise. you are just listening to a pack of crap from conspiricy theory nuts.  (+ info)

How can one genetic mutation cause sickle-cell disease?


Sickle Cell disease is caused by a point mutation in the DNA. A hemoglobin protein normally having the amino acid Valine is substituted for Glutamic acid in the sickle cell protein. Looking at the structure and function, how can one simple mutation can cause such a big problem. Would you expect a change from glutamic acid to aspartic acid to cause as big a difference?
----------

Single-gene mutations are a very large chunk of genetic diseases. To understand this better, lets break down the process of making a protein from the genetic material. Please note that I do not have much knowledge on the actual mutation in sickle cell, but I can explain how this can create huge problems in general. The problem lies in that proteins do not only have primary structure but secondary, tertiary, and quaternary structure.

First, we transcribe the DNA. In this case, the problem does not happen here, so we will skip the details. Basically, we are going to take the gene that will produce the protein and transcribe it onto a strip of RNA. Then, we will take that RNA over to the ribosome, where we translate it into amino acids. A group of 3 bases is called a codon, and the codon tells the ribosome which amino acid to add to the chain. There are "start" and "stop" codons that tell the ribosome when the protein begins and ends. One base pair change can add or eliminate a start or stop codon, so if this happens you end up with a chain that is either too long or too short. Again, this is not where the problem happens. Instead, they just substitute the wrong amino acid, and stick in a valine instead.

There are more steps to creating this protein, and this is where the problem lies. The amino acids on each individual chain will interact with each other first, folding to create an electrically stable molecule. Then, the individual chains that make up the protein will interact and fold together. Where each of the folds lie is based on the electrical charge of the molecule. Valene is a non-polar, hydrophobic amino acid. When you swap that for Glu, a negatively charged, acidic molecule, the tertiary and quaternary structure of the protein changes dramatically. Aspartic acid is another AA in the acidic group, so the structure should be about the same as glutamic acid, but I am not sure of all of the specific possibilities of that.

Remember from organic chemistry, structure determines function. A sickle hemoglobin cell is shaped in a way that it cannot carry oxygen because of the simple switch in amino acids.  (+ info)

does anyone know of a rare genetic disease?


I need to write a report on a rare genetic disease and i cant think of one? can someone help me?
----------

Mitochondrial myopathy....a lot of doctors didn't even know of this disease
when I had a muscle biopsy done about 15 years ago to test for it....it was generally diagnosed by a genetic doctor.  (+ info)

what is a genetic predisposition to serotonin imbalance?


(cause: weight loss, over- exercising /vomiting)

this question has to do with the biological factors that cause eating disorders/anorexia.
----------

I found a paper on this Nadia which outlines a whole lot of information (see below).

Hope this helps  (+ info)

A male with an X linked recessive genetic disorder has children with a female who does not carry the disease?


1. could any of their children have the genetic disorder?
2. could any of their children be carriers for the disorder?
----------

Punnet squares, huh? Haha.

1. No, in terms of drawing the actual punnet square, none of their children will actually have the disease itself.

2. Yes. The chances they will be a carrier is 50%.  (+ info)

What do you know about the genetic disease, PKU?


I need this for a research paper I am doing for English and biology. I need to interview someone who knows a lot about this disease. I just need to ask you a few questions, not a ton. Thanks.

go to wikipedia it should have everything about it  (+ info)

Should i tell my boyfriend that a have a genetic disease?


I have a mild case of a genetic disease, (but if we were to have a child, there is a 50% chance of the child of having it, and there is no determining the severity of how they will have it). I have not disclosed this secret, not just the kid thing, but all together because i fear that he will leave me. Our relationship is becoming quite serious now...and well, telling him is a double-edged sword...
----------

If he drops you because of a genetic defect it will hurt more later on when he finds out than now. If his love for you is real and not just lust then he will stick by you and be honored by your disclosing such a private matter. You have nothing to loose by sharing this truth with him and it will help you both work together on a solution that will not bring a genetic defect on your children.
And it is quite responsible of you to be thinking ahead of the danger to your potential children. I wish you all the best with him.  (+ info)

Can you have a genetic predisposition for anxiety?


Sorry, I have no idea if I spelled that right...

Anyway, my dad used to have an anxiety problem, and now I also have one. I'm 13. He didn't tell my mom or his current girlfriend (my parents are divorced). Do you think my dad should have told my mom before they started having kids?
My dad said he had an issue in high school, but he married my mom when he was 32. He turns 47 in September.

Sorry for the repeated stuff!!! My computer messed up and submitted it more than once..
I've had an anxiety problem for a couple of years, but I only figured out I had one last September when it got really bad...My parents are now getting me help
----------

Welcome to the club. Now that science has proven a genetic composition to some mood disorders, I would say that he should tell his girlfriend if they are contemplating marriage and/or children. If the anxiety was long gone when he met your mom, I'm not so sure he or anyone else would feel an obligation to tell her. No one knew it was genetic.

Hope you are receiving successful treatment for your anxiety.  (+ info)

is there really a genetic predisposition for alcoholism?


so i'm starting to drink on a regular basis. nothing excesive at this point. anyway, my dad was a bit of an alcholic and one of my close friends is constantly warning me that i have a hire risk of becoming one myself if i start/keep drinking. is he right?
----------

i don't think there is an "alcoholic" gene. i think parents pass down to their children the ways that they cope with stress and other situations. if you find yourself mimicking what your parents did and you have concern about it, maybe you'd want to take a step back and examine why you are doing what you are doing in the first place. people drink alcohol, plain and simple. if you are just drinking it for fun and socialization, that can be fine. if you are drinking to 'drown your sorrows' or build self-confidence for those episodes, maybe you want to rethink it. i had an alcoholic father and i drink alcohol. i don't consider myself an alcoholic because i have a different motivation, in my opinion, and don't do it excessively.  (+ info)

What are you thoughts on the possibility of a genetic predisposition to alcoholism?
