The instructions for making proteins are coded in the

messenger RNA /mRNA!

Explanation:

mRNA is a type of RNA that carries the information about the type of protein to be made

It carries it to the ribosomes for the production of proteins

Ribosomes decode the information on the ribosome and make protein from the amino acid sequence directed by the mRNA

The mRNA or messenger RNA contains information for protein coding.

The messenger RNA or mRNA conveys the directions for making proteins. Like DNA, proteins are polymers: long chains amassed from prefab subatomic units, which, on account of proteins, are amino acids. An enormous sub-atomic machine called the ribosome interprets the mRNA code and collects the proteins.  

Ribosomes read the message in mRNA in three letter "words" called codon, which mean explicit amino acids or a guidance to quit making the protein. Every conceivable three letter course of action of A, C, U, G (e.g., AAA, AAU, GGC, and so on) is a particular guidance and the correspondence of these directions and the amino acids is known as the "hereditary code".

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.
