Summary:In this passage, sulfur is being added to sugar-phosphate DNA to modify synthetic oligonucleotides. Nature has been using phosphorothioate modidfications of DNA for a while now.


Questions:
What are the major functions of nucleic acids in the cell?It identifies the DNA
What are the differences in RNA and DNA? DNA carries information while RNA makes proteins and acts as the messenger.
List three things you learned from this article in your own words.
I learned that sulfur can be added to DNA and that bacterial genes give bacteria the ability to employ modidfications ontheir own.
What impact would the absence of this organelle have on the cell?Modifications won't be able to be made.

Summary:FAK is linked to a type of cancer called skin carcinomas.Mice were used to disable the function of FAK in the mammmary glands. The mice being the enzymes, stopped a tumor from growing and harming.

Questions:
What reactions does this enzyme catalyze? the growth of tumors
How is the cell affected if this enzyme is removed?the tumor growth is ceased
List three things you learned from this article in your own words.
1) I learned that FAK is linked to skin carcinomas
2) Mice can lose thier life during these experiments that try to save humans
3)Mice can stop tumor growths
What impact would the absence of this molecule have on the cell? If this molecule was absent then the tumor would continue to grow.

Summary: The most common type of liver cancer is hepatocellular carcinoma. It causes about one million deaths each year. A lot of people die because the therapies are limited which causes scientists to look for proteins inside the body.

Questions:
What is the major role of this molecule in the cell? To identify the presence of liver cancer.

List three things you learned from this article in your own words.
1) PROTEINS ARE USED TO FIND THE DISEASE
2)PROTEINS ARE USED TO IMPROVE THE DIAGNOSIS
3)HEPATOCELLULAR CARCINOMA IS A TYPE OF CANCER
