Question

1) Сколько нуклеотидов потребуется при удвоении молекул ДНК, если аденина=600тыс, Г=2400тыс2) В одной молекуле ДНК Т=24% от общего числа нуклеотидов. Найти Г, А, Ц (%)

Answer 1

1- Аденин = Тимину,600тыс*2= 1200тыс,Гуанин=Цитозину значит 2400тыс*2=4800тыс,все кладываем=6000тыс

 

2- Тимин=Аденину=> их обоих по 24*2=48% вместе,остался Гуанин и Цитозин,на которых осталось 100-48=52% 52 делим на 2 =26% на Гуанин и Цитозин 

Answer 2

1) аденин=тимн=600тыс

цитозин=гуанин=2400тыс

следовательно всего будет (600+2400)*2= 6000тыс

2) Т=А= 24%

Г=Ц= (100- 24*2)/2=26%

Answer 3

Number of nucleotides required for DNA replication:

To determine the number of nucleotides required for DNA replication, we need to know the base composition of the DNA molecule. The four nucleotides in DNA are adenine (A), guanine (G), cytosine (C), and thymine (T).

1) If the number of adenine (A) nucleotides is 600,000 and the number of guanine (G) nucleotides is 2,400,000, we can calculate the number of nucleotides required for DNA replication by summing up the counts of all four nucleotides.

The total number of nucleotides required for DNA replication can be calculated using the formula:

Total number of nucleotides = 2 * (number of adenine + number of guanine + number of cytosine + number of thymine)

Let's calculate it:

Total number of nucleotides = 2 * (600,000 + 2,400,000 + X + X)

Since we don't have the values for cytosine (C) and thymine (T), let's use the information provided in the second question to find the values of guanine (G), adenine (A), and cytosine (C).

Base composition of DNA:

2) In one DNA molecule, thymine (T) makes up 24% of the total number of nucleotides.

Let's calculate the percentages of the other three nucleotides:

- Adenine (A) percentage = 100% - Thymine (T) percentage = 100% - 24% = 76% - Guanine (G) percentage = Cytosine (C) percentage (since the percentages of G and C always add up to 100%)

Now, we can calculate the values of guanine (G), adenine (A), and cytosine (C) using the percentages and the total number of nucleotides:

- Guanine (G) = (Guanine percentage / 100) * Total number of nucleotides - Adenine (A) = (Adenine percentage / 100) * Total number of nucleotides - Cytosine (C) = (Cytosine percentage / 100) * Total number of nucleotides

Let's calculate the values:

- Guanine (G) = (50% / 100) * Total number of nucleotides - Adenine (A) = (76% / 100) * Total number of nucleotides - Cytosine (C) = (50% / 100) * Total number
