Which organelle makes proteins for a cell?
The ribosomes are the organelles responsible for protein synthesis in a cell. They read the messenger RNA and assemble amino acids into proteins based on the genetic information.
What uses the information in nucleic acid to synthesise proteins?
Ribosomes use the information in nucleic acids (specifically mRNA) to synthesize proteins through a process called translation. Transfer RNA (tRNA) molecules bring amino acids to the ribosome based on the information in the mRNA, and peptide bonds are formed between the amino acids to create the protein.
Which of these organelles is coverd in ribosomes?
The rough endoplasmic reticulum is covered in ribosomes. In fact, it is called 'rough' because of the presence of ribosomes which give it a rough looking appearance. Technically, the rough endoplasmic reticulum is actually the region of the greater 'endoplasmic reticulum' where protein synthesis takes place. Another region of the endoplasmic reticulum is the 'smooth endoplasmic reticulum' where lipids are synthesized and other metabolic functions take place. The quantity of rough versus smooth endoplasmic reticulum is somewhat in flux and varies based on the needs of the cell.
Both DNA and mRNA carry information for making things-How is this information carried so that the correct products are made?
DNA carries genetic information in the form of a sequence of nucleotide bases, which is transcribed into mRNA. This mRNA then carries this information to the ribosomes, where it is used to determine the sequence of amino acids in a protein. This process ensures that the correct products are made based on the information stored in the DNA.
How are secretory proteins and membrane molecules synthesized?
Protein synthesis begins in the cell nucleus. A given gene (made of DNA) is activated, and it then creates RNA which travels to the ribosomes of the cell, which are essentially microscopic protein factories. The RNA gives the design of the protein, and the ribosomes create the protein based on that design. The raw material for the proteins, which is amino acids, is already present in the cell's cytoplasm.

What do researchers think the origin of mitochondria are and why?
According to one hypothesis, once there was the ancestor of a eukaryotic cell, which swallowed a bacterium. But instead of digesting it, the eukaryotic cell used the bacterium to yield energy by feeding it. In other words, a symbiosis formed, where the former bacterium is protected from foes and gets sugar, whereas the eukaryote gets ATP.This hypothesis is based on the facts ofthe double cell wall of the mitochondria (the inner one rough like a bacterium one, the outer smooth like from a lysosome)the own DNA of the mitochondriathe 70S ribosomes (like bacteria have it) instead of eukaryotic 80S ribosomes

How many endoplasmic reticulum does one cell exist?
A cell typically has multiple endoplasmic reticulum (ER) structures. There are two types of ER - rough ER (with ribosomes attached) and smooth ER (without ribosomes). The number of ER structures can vary based on the cell type and its function.

A cell organelle in which protein is made?
Ribosomes are the cell organelles responsible for protein synthesis. They can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read messenger RNA and assemble amino acids into proteins based on the genetic information.

What surrounds ribosomes?
Ribosomes are found in the cytoplasm of a cell. They can also be associated with the endoplasmic reticulum in eukaryotic cells, forming the rough endoplasmic reticulum. Ribosomes are the sites of protein synthesis in a cell.
What evidence indicates that mitochondria and chloroplasts were once free-living organisms?
Both have their own DNA, and manufacture their own RNA and proteins. When the DNA was examined, it was resembled the DNA in free-living organsims known as blue-green algae, so it was hypothesized that these organelles were once free-living and then became endosymbionts with another organism.
What produces the proteins for the cell?
robosomes in the endoplasmic reticulum.
What does not directly participate in translation ribosomes mrna trna DNA?
DNA does not directly participate in translation. Rather, it provides the template for mRNA synthesis through transcription. mRNA carries the genetic information from DNA to the ribosomes, where tRNA helps to assemble amino acids into a protein based on the mRNA sequence.
