The process of protein synthesis involves two steps such as transcription and translation. In the process of transcription the encoded information in the DNA is transcripts or encoded into messenger RNA or mRNA inside the nucleus. This mRNA then comes out of the nucleus to the cytoplasm. In the process of translation the mRNA molecule attach with the ribosomes and tRNA molecules to synthesise the protein.
Looking at the onion root tip under the microscope you can see large, rectangular cells with visible distinct cell walls surrounding it (cells have a more regular shape because of the wall). Inside the cells, you can notice darkly stained nucleus, large vacuoles at the center and sometimes small granules within the cytoplasm. Looking the onion root tip under the microscope is often the way to observe mitosis. Usually, you cannot see organelles such as mitochondria, ribosomes, rough and smooth endoplasmic reticulum, centrioles and Golgi body as they appear translucent and because are too small to be seen under the light microscope (electron microscope required). Also, chloroplasts are not present in an onion cell because it is not a photosynthetic cell.
Explanation:
yes
any one free out
sin theta equals to cos theta then the value of sin 2 theta
The phospholipid bilayer is a universal component of all cell membranes. Each phospholipid molecule has a hydrophobic(water repelling) and a hydrophilic( attracted to water) end. This allows the phospholipids to arrange themselves in a way that makes a cell membrane not able to dissolve in water. The bilayer is also semi-permeable which allows only certain molecules to enter the cell.
hope this helps
