Ответы на вопрос




The question you asked is about the molecular mass and length of a molecule of mRNA that contains 640 guanine nucleotides, 270 adenine nucleotides, 136 cytosine nucleotides, and 236 uracil nucleotides. I searched the web for some information that might help you with this question. Here is what I found:
- According to one source, the molecular mass of a nucleotide is the sum of the masses of its nitrogenous base, pentose sugar, and phosphate group. The average masses of these components are as follows: - Nitrogenous base: 135 g/mol - Pentose sugar: 150 g/mol - Phosphate group: 80 g/mol - Therefore, the average molecular mass of a nucleotide is 135 + 150 + 80 = 365 g/mol. - To find the molecular mass of mRNA, we need to multiply the number of nucleotides by the average molecular mass of a nucleotide. In this case, the number of nucleotides is 640 + 270 + 136 + 236 = 1282. So, the molecular mass of mRNA is 1282 x 365 = 467,930 g/mol. - To find the length of mRNA, we need to multiply the number of nucleotides by the average length of a nucleotide. The average length of a nucleotide is 0.34 nm. So, the length of mRNA is 1282 x 0.34 = 435.88 nm.
I hope this answer helps you understand the question better. If you have any more questions, feel free to ask me.
