Question

Скорость удлинения молекулы информационной рнк составляет 50 нуклиатидов в секунду.Сколько необходимо времени для синтеза информ.РНК ,содержащую информацию о структуре белка.с молекулярной массой 24 750.если молекулярная масса одной аминокислоты 110.Ответ поясните.

Answer 1

Итак, если молю масса 24750, то количество аминокислот - 24750/110=225.
Каждая аминокислота кодируется 3-я нуклеотидами, получаем 675 оснований + 3 нуклеотида стоп-кодона, не кодирующие ничего, итого 678.
Время  транскрибции - 678/50=13,56 секунд.

Answer 2

Calculation of Time Required for Synthesis of RNA

To calculate the time required for the synthesis of RNA containing information about the structure of a protein, we need to consider the speed of elongation of the RNA molecule and the molecular mass of the protein.

Given: - Speed of elongation of the RNA molecule: 50 nucleotides per second - Molecular mass of the protein: 24,750

To calculate the time required, we need to determine the number of nucleotides in the RNA molecule. Since the molecular mass of the protein is given, we can use the molecular mass of one amino acid (110) to estimate the number of amino acids in the protein. Then, we can use the relationship between the number of nucleotides and the number of amino acids in the RNA molecule to calculate the number of nucleotides.

Let's proceed with the calculation:

1. Calculate the number of amino acids in the protein: - Molecular mass of the protein: 24,750 - Molecular mass of one amino acid: 110 - Number of amino acids = Molecular mass of the protein / Molecular mass of one amino acid - Number of amino acids = 24,750 / 110

Number of amino acids = 225

2. Calculate the number of nucleotides in the RNA molecule: - Number of nucleotides = Number of amino acids * 3 - Number of nucleotides = 225 * 3

Number of nucleotides = 675

3. Calculate the time required for synthesis: - Speed of elongation of the RNA molecule: 50 nucleotides per second - Time required = Number of nucleotides / Speed of elongation of the RNA molecule - Time required = 675 / 50

Time required for synthesis = 13.5 seconds

Therefore, it would take approximately 13.5 seconds to synthesize the RNA molecule containing information about the structure of the protein, given the provided parameters.

Please note that the calculation assumes a constant speed of elongation and does not consider other factors that may affect the synthesis process.
