Question

Ribosomes are :&#8211;a)Positively chargedb)Negatively chargedc)Amphotericd)NeutralCorrect answer is option 'B'. Can you explain this answer?

Answer

There is no free cytoplasm protein with a high positively charge to make them settle into ribosomes

Answer

Answer is positively charged. Because they are associated with aminoacids like lysin and arginine and that helps them bind with negatively charged mRNA.

Answer

Ribosomes contains protein and RNA. The proteins are positively charged and the RNA carries negative charge.Here the RNA plays fundamental role in its structure and its content is also more than proteins. Hence Ribosomes are negatively charged.

Answer

Ribosomes are negatively charged.

Ribosomes are small organelles found in all living cells. They are responsible for protein synthesis, which is the process of assembling amino acids into polypeptide chains according to the instructions encoded in the messenger RNA (mRNA). Ribosomes can be found either freely floating in the cytoplasm or attached to the endoplasmic reticulum.

What is charge?

Charge refers to the property of matter that gives rise to electric force. It can be positive, negative, or neutral. In the context of ribosomes, charge refers to the overall net charge of the molecule.

Ribosomes and their charge

Ribosomes are composed of two subunits, the large subunit and the small subunit. These subunits are made up of ribosomal RNA (rRNA) and proteins. The rRNA molecules are negatively charged due to the presence of phosphate groups in their structure. These phosphate groups contain negatively charged oxygen ions. The proteins associated with ribosomes can also contribute to their overall charge, but they generally have a neutral or slightly positive charge.

Electrophoresis

Electrophoresis is a technique used to separate charged molecules based on their size and charge. It involves applying an electric field to a gel matrix, causing charged molecules to migrate towards the positive or negative electrode depending on their charge. By subjecting ribosomes to electrophoresis, it has been observed that they migrate towards the positive electrode, indicating that they possess a net negative charge.

Conclusion

In conclusion, ribosomes are negatively charged due to the presence of negatively charged phosphate groups in their rRNA molecules. This charge allows them to be separated from other molecules using electrophoresis. Understanding the charge of ribosomes is important for studying their structure, function, and interactions with other molecules in the cell.

Answer

-21 Ribosomes are composed of RNA and protein. Ribosomes are 62% RNA and 38% protein formed into two complexes in prokaryotes, the 50S ribosome subunit and the 30S ribosome subunit. Ribosomeassociated proteins are positively charged. This helps them to bind to the negatively charged mRNA.

Answer

Ribosomes contains protein and RNA. The proteins are positively charged and the RNA carries negative charge.Here the RNA plays fundamental role in its structure and its content is also more than proteins. Hence Ribosomes are negatively charged.
