Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Genes code for ____
A
Proteins
B
Groups of proteins
C
all of the above
D
None of the above
Explanation: 

Detailed explanation-1: -Genetic code refers to the instructions contained in a gene that tell a cell how to make a specific protein.

Detailed explanation-2: -The genetic code is a set of instructions that direct the translation of DNA into 20 amino acids, the basic units of proteins in living cells. The genetic code is made up of codons, which are three-letter chains of nucleotides. Each codon codes for one specific amino acid.

Detailed explanation-3: -The genetic code had to be a “language”-using the DNA alphabet of A, T, C, and G-that produced enough DNA “words” to specify each of the 20 known amino acids. Simple math showed that only 16 words are possible from a two-letter combination, but a three-letter code produces 64 words.

Detailed explanation-4: -The DNA of life on Earth naturally stores its information in just four key chemicals-guanine, cytosine, adenine and thymine, commonly referred to as G, C, A and T, respectively.
