My flat is beautiful and sunny. It has got five rooms. They are two bathrooms, a kitchen, a bedroom and a living room. The living room is big and cosy. There is a big TV, a sofa and two armchairs in it. My mum and I love sitting there watching TV.
My favourite room is a bedroom. It is smaller than the living room. But it is my favourite place because it is warm and comfortable. There is a bed and two cupboards. My bed is red. It looks like a real car. You can see a computer and a small TV in my bedroom. The room has got an aquarium.There are a lot of exotic fish in it. Every day I feed my fish and my mum helps me to clean my room. I like doing homework and playing in my room.
I like my flat!

Мы имеем 300 молекул тимина на одной цепочке.
Всего нуклеотидов в первой цепи - 100%
Тимина - 100% - (30+25+35)= 10%
Если 300 молекул тимина составляют 10%, то 100% - это 3000 молекул всех нуклеотидов на одной цепи, а по правилу комплементарности, на 2ой цепи будет столько же нуклеотидов, следовательно на данном отрезке ДНК содержится 6000 молекул дезоксирибоз
Теперь находим число остальных нуклеотидов в первой цепи:
Аденин 30%= 900
Цитозин 25% = 750
Гуанин 35 % = 1050
Тимин 10% = 300
