Answer:
A RNA polymerase separates the hydrogen bases of a gene to produce a strand of messenger RNA, which leaves to nucleus. When a ribosome attaches itself to the messenger RNA, it reads the RNA 3 bases at a time to build amino acids which are then folded into proteins.
More explained process:
Note: The description below will explain the process of “protein synthesis”, in which the mRNA (messenger RNA) takes part of.
In the process of protein synthesis, the first step is called “transcription”. In transcription, the mRNA (messenger RNA) unwinds DNA base pairs, and pairs it with the single strand of RNA (A,U,C,&G) . Then the mRNA moves out of the nucleus and into the cytoplasm to ribosome. That process is called “translation”. In translation, there is a molecule called tRNA (transfer RNA). There is an amino acid which corresponds to the base pairs of RNA in top, which will create a chain of amino acids. [ For example, the bases are AUC, the corresponding amino acid will be isoleucine (Ile). Next, the tRNA molecules carry the amino acids to mRNA, reads the RNA 3 bases at a time to build an amino acid chain which are then folded into proteins.
All of the above, they are all good forms of decreasing plosion but B is the best answer <span />
Answer: 1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria
2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance. The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.
4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.
Transport vesicles move molecules within the cells.
Vacuoles are vesicles that contain mostly water.
