Question

Белок состоит из 158 аминокислот. Какую длину имеет определяющий его ген, если расстояние между двумя соседними нуклеотидами равно 3,4 наномикрон?

Answer 1

Код триплетен: 1 аминокислоте соответствует 3 нуклеотида
158*3 = 474 нуклеотида
474* 3,4 =1611, 6 нм

Answer 2

Protein Length Determination

The length of a protein is determined by the number of amino acids it contains. In this case, if a protein consists of 158 amino acids, we can calculate the length of the gene that encodes it based on the given distance between adjacent nucleotides.

To calculate the length of the gene, we can use the fact that each amino acid is encoded by a sequence of three nucleotides, known as a codon. Therefore, the length of the gene can be calculated by multiplying the number of amino acids in the protein by 3 (the number of nucleotides per codon).

Calculation: - Number of amino acids in the protein = 158 - Distance between adjacent nucleotides = 3.4 nanometers

Using the formula: \[ \text{Gene length} = \text{Number of amino acids} \times 3 \]

We can calculate the length of the gene that encodes the 158-amino acid protein.

Result: - Gene length = 158 amino acids * 3 nucleotides/amino acid = 474 nucleotides

Therefore, the gene that encodes a protein consisting of 158 amino acids and with a distance of 3.4 nanometers between adjacent nucleotides would have a length of 474 nucleotides.
