Question

The organelle associated with protein synthesis in a cell is :
A. Mitochondria
B. Lysosomes
C. Ribosomes
D. Chromosomes

Answer 1

Solution

For many cell functions such as repairing damage or directing chemical processes proteins are needed. Protein biosynthesis (or protein synthesis) is a core biological process, occurring inside cells, balancing the loss of cellular proteins through the production of new proteins. Proteins perform a variety of critical functions as enzymes, structural proteins, or hormones and therefore, are crucial biological components.

Complete answer:
1. Ribosomes are organelles that take part in protein synthesis.
2. Protein is an important element for many cell functions such as repairing damage or directing chemical processes.
3. Ribosomes can be seen floating with cytoplasm or attached to the endoplasmic reticulum.
4. The ribosome is made of RNA molecules and proteins, they together form a factory that helps in protein synthesis.
5. George E Palade was the scientist that discovered ribosomes in 1955.
6. Ribosomes are differently structured in prokaryotes and eukaryotes.
7. In prokaryotes, they are sized around 20nm in diameter and are made of 65% RNA and 35% ribosomal proteins.
8. In eukaryotes, they are approximately between 25 and 30nm in diameter. They have 18 sRNA and 33 proteins.
9. The unit that is used to describe ribosomal subunits and its rRNA fragments is the Svedberg unit, which is a measure of the rate of sedimentation in centrifugation.
10. Ribosomes also have other functions such as acting as a catalyst in two important biological reactions.
11. Translation of mRNA to protein carried out by ribosomes. The mRNA consists of codons that are decoded by ribosomes to form proteins.

Additional Information:

So, the correct answer is “Option C Ribosomes”.

Note: Each organelle of the cell has a unique function. Such as the mitochondria which are very well known as the powerhouse of the cell provides energy to carry out the functions whereas lysosomes carry out the process of engulfing foreign particles.
