romanna [79]

Answer:

different proteins

Explanation:

All the cells of the body are derived from same cell still different cells have different characteristics or phenotypes. For example, the hemoglobin is present in RBCs only not in any other cell. This is because of a process called gene expression.

This process regulates expression or repression of different set of genes. This makes embryonic cells to become specialized cells that is to perform a specific function. The gene contains DNA which gets transcribed to RNA and then to proteins. The different proteins provides different specificity to cell.

Life as we know it depends on the genetic code: a set of codons, each made up of three bases in a DNA sequence and corresponding
Nana76 [90]

The right answer is 5.

To answer this question it is sufficient to take the same approach as the one that concluded that each amino acid is equivalent to 3 codons.

We have 17 amino acids, each of which must have at least one unique code (having two nucleotides A and T) .

it is enough to apply this time to count the number of possible codons to be generated according to the number of nucleotides:

nucleotide set ^ number of nucleotides = number of codons .

2 ^ 1 = 2 (<17)

2 ^ 2 = 4 (<17)

2 ^ 3 = 8 (<17)

2 ^ 4 = 16 (<17)

2 ^ 5 = 32 (> 17)

So, each amino acid has a codon of 5 nucleotides.
