Answer:
Rough endoplasmic reticulum looks "rough" under a microscope because it has ribosomes attached to its surface.
Explanation:
Rough endoplasmic reticulum (RER) is a membrane organelle found in the cytoplasm of eukaryotic cells, which has ribosomes attached to its outer surface. Hence the name, rough endoplasmic reticulum. It has an important role in the synthesis of proteins. In ribosomes, the proteins are synthesized. The smooth endoplasmic reticulum (SER) does not contain ribosomes. It has an impotant role in the synthesis and storage of lipids. The proteins that are synthesized in the ribosomes are packaged into vesicles and transported to the Golgi apparatus by the rough endoplasmic reticulum. The Golgi apparatus which is located near the RER, modifies, transports and packages proteins for delivery to targeted destinations.
Material in the cell nucleus made up of DNA and various kinds of protein is called chromatin.
It’ll be A - UCG
In tRNA;
- A is complementary to U
- C is complementary to G
Cancer cells do not undergo apoptosis, which is where where the cells are signaled to self destruct. They do not respond to growth inhibitors. The only answer choice left is that they exhibit metastasis, which they do.
The importance of mitosis to living organisms living organisms is that it allows organisms to grow in size and repair themselves.<span> When an organism grows, its cells do not grow larger; they divide to make more of themselves through the process of mitosis, or cell division.
