What does an mrna molecule play in the flow of information for protein synthesis

mRNA plays a crucial role in protein synthesis. It carries the information for synthesis of a particular protein from the DNA to the ribosomes.

In the cell nucleus, this information is copied (transcribed ) from DNA and onto mRNA. mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome.

Transfer RNA or tRNA  begins to read (translate) the information on the attached mRNA and from the pool of free amino acids in the cytoplasm, fetches the amino acids that corresponds to the information, and brings them to the ribosome where they are linked together into a chain, forming the primary structure of protein.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
