“No man is an island.”This saying is also true for organisms in an ecosystem. No organism exists in isolation. Individual organisms live together in an ecosystem and depend on one another. In fact, they have many different types of interactions with each other, and many of these interactions are critical for their survival.
Answer:
A mutation in Ras protein which will cause hyperactivity will eventually lead to cancer.
Explanation:
Ras protein was first discovered in Rous sarcoma virus (RSV) and it is a proto-oncogene product. In normal conditions, it plays an important role in cellular signalling but in case of gain of function/hyperactivity it gets converted into cellular oncogene. In several types of cancers a point mutation has been reported in Ras protein.
Just like G protein, it is also a GTPase switch protein but unlike G protein which is trimeric, it is monomeric. In the plasma membrane, it is attached with the help of lipids like prenyl or palmitoyl groups. During signal transduction pathway when it gets activated, it downstream activates MAPK pathway and causes gene expression but when it gets hyperactivated it causes over expression of genes leading to cancer.
True - The Big Bang Theory is the most popular THEORY out their. Meaning it is NOT a fact
The nucleus is in the middle of a cell
and it controls the different part of the cell
Explanation: this experiment is long term which means patience is compulsory. you need to have a wild sloth and a domesticated sloth adopted right at their birth (he should be in a controlled environment that mimics the wild). your domesticated sloth shouldn't have the algae. at their middle age, you should compare them with them from every aspect.
