This is the blog for Ms. Hero's Biology Class at Carlmont High School. Articles related to what we are studying in class will be posted with prompts for student response.

Can you imagine a fast food restaurant without french fries?
Potatoes are in trouble, but scientists are using genes from other organisms to protect potatoes. Read New Gene Fights Potato Blight. How can genetic engineering help potato farmers? How does this relate to protein synthesis and our transformation lab?
The disease named blight destroys potatoes, and toxic chemicals were previously applied to potatoes to prevent blight. Now with genetic engineering of potatoes, the potatoes can prevent blight by themselves, possibly improving the environment. The potato called Solanum bulbocastanum is protected from blight, and scientists from Wisconsin and California took genes from it and inserted the genes into groups of potatoes. The group that remained safe from blight received the proper gene that coded for blight preventing proteins. Now, this gene can be inserted into potatoes to stop blight, therefore helping farmers. This genetic engineering of potatoes is similar to our transformation lab. In both, new genes are inserted into living things, so that the organisms produce new proteins that consequently change their phenotypes.
This article is explaining how potatoes are catching a disease called blight and its making the potato plant die and not developing potatoes as it should. Potatoes are so good when they are made into frenchfries or chips. Its delicious so scientists then discovered a potato called solanum bulbocastanum they got the genes from the batch and then exposed four of them with blight and a group of them remained healthy. so there is ways to prevent the blight diesease in potatoes and thats what i learned about this article.
Genetic engineering helps potato farmers because it changes organisms DNA using lab techniques. It relates to our transformation lab because we have been using genetic engineering in the labs we have been doing. Same thing how it relates to protein synthesis. Its parts of the steps of Bacterial Transformation. Also genetic engineering helps farmers change organisms which is something that they can't really do themselves.
Potatoes, one of America's favorite foods, are now in danger of extinction. A disease called blight was responsible for the Irish famine in the 1800s. This disease is still around, in fact, farmers spend billions of dollars a year on resisting blight with toxic chemicals. It appears that scientists have finally found a solution in a potato. Solanum bulbocastanum is a potato that is not affected by blight. Scientists found the gene that is immune to blight and tried putting it into different organisms, like what we did with pGlo and E coli. This made the genetically engineered potatoes immune. Now farmers have a cheap, environmentally friendly way to fight of blight, genetic engineering.
Genetic engineering will help potato farmers fight against blight, a disease that targets potato plants. Scientists will take a gene from a potato immune to blight and add it to other potatoes. This relates to our transformation lab because we altered the e coli. virus to be able to survive in the presence of ampicillin. I find this article interesting because its interesting that a disease could kill a whole species of plant.
The article was about potatoes being genetically altered. this helps farmers because then they do not have to pay a lot of money for toxics to protect them. This is also better for the environment. This relates to what we are learning because the potatoes are being genetically altered. We are learning how to genetically alter living things and genetic engineering in class.
http://www.sciencenewsforkids.org/articles/20030723/Note2.asp Scientists were conducting expiriments on potatoes to protect the potatoes from disease. There was a perticular potatoe plant that was ammune to a disease called blight. The scientists' expirimentwas to find the gene that made this immunity possible. They tested four plants and the test narrowed it down to one: the gene they were looking for. So, now we are debating if this is the right thing to do, because it might alter the environment or evolution.
potato are the biggest problem for the farmers. the serious disease is called blight threaten in all over the wrold. farmers spend billion of dollars to fight this disease. scientists have found a new weapon against blight. farmers use toxic chemicals to fight the blight.
Blight is a disease causing many threats to farmers’ potatoes. With genetic engineering, scientist can redesign the gnome on potatoes to protect them from blight. They can redesign the potatoes gnome by using the genes from the Solanum bulbocastanum potatoe, known to be immune to blight. This way, farmers don’t have to worry about their crops. This is similar to our labs in Biotech, when we used ampicillin to fight against the bacteria E. coli to stop it from spreading.
Potato farmers can greatly utilize the advantages of genetic engineering. Scientists can now extract the genes of a certain type of potato, and insert the gene into other types of potatoes. This gene can be used in order to protect potatoes from blight, a disease that kills many potatoes and leaves many people in famine. This relates to our class in labs because the concept of transformation is within both experiments. Both include the insertion of DNA foreign than their naturally found one. They are also both used as an immunity against something that is trying to kill them.
scientists say they have found a new weapon against blight: a potato that has already solved the problem on its own.
A wild variety of potato called Solanum bulbocastanum is immune to blight. Researchers from Wisconsin and California extracted four carefully chosen genes from a batch of S. bulbocastanum plants. They then spliced one gene into each of four groups of potato plants.
When the researchers exposed all four groups of potatoes to the funguslike organisms that cause blight, one bunch stayed healthy. The scientists think the gene that went into the healthy bunch is critical for blight resistance.
Farmers normally use toxic chemicals to fight blight. Using genetic engineering techniques could be less expensive and kinder to the environment, some researchers say.
Other people are more concerned about transferring genes from one species to another. No one knows how the technology will affect the environment or evolution.
Genetic engineering is when scientist fixes things to improve them. Scientist found a way to do this with potatoes so they don’t get diseases. They found out that farmers usually use toxic chemicals to solve the disease. Genetic engineering techniques are less money and are also kinder to the environment. This relates to protein syntheses and our lab. It relates it because it shows how you can change things to make them better like we did in our jellyfish lab with the bacteria. This is what they do in genetic engineering, that better things like the potato.
In the article, "New Gene Fights Potato Blight" the author talks about how a certain disease called blight that is effecting the growth and the population of the potato issue might be solved just in some easy genetic altering steps. A group of scientist from Wisconsin and California worked on the issue of the disease that is effecting every person in the world, since potatoes have been humans primary source of vegetable, and everyone's favorite food people had to solve the problem. They picked a certain type of potato called "Solanum bulbocastanum" that is immune to the blight and extracted its gene by taking part of the DNA of the potato and altering it into another type. After a huge success, the disease that everyone were concern about was solved and the potato are secured from the blight. Genetic Engineering could lead mutations into good helpful sources like this type of an example, humans have now evolved at the point where they could play around with mother nature and its secret genetic codes to prevent certain kinds of diseases.Some day I think scientist would finally solve the issue with cancer and hopefully humans would have to care about one less thing again.
