Ответ:

Аденин и Тимин вместе 40

Аденин 20 по принципу

значит сумма цитозина и гуанина=100- 40 = 60

по принципу комплементарности гуанин и цитозин будут равны.

ответ: фитолизин = 30

7. Обсудите высказывания (1—9), сделанные обвиняемыми. Подберите для каждого высказывания вид совершенного преступления, пред-
ставленного в рамке.

1. “I arrived home late and found that I’d forgotten my keys. I didn’t
want to wake my wife up, and I saw there was a ladder in the garden of the
house next door. I got the ladder and climbed in. We‘ve just moved to the
house and I didn’t realise I was in the wrong street”.
2. “I was walking my dog when I saw a gun lying on the ground. I picked
it up — it was still warm — and at that moment I saw the body lying in the
long grass. I went across to look and it was my business partner. That’s when
the police arrived”.
3. “I opened the bank account in a false name as a way to help my employer
pay less tax- It’s perfectly legal. I kept meaning to tell him, but somehow I just
forgot. I bought the villa in France with my own money. It was an inheritance”.
4. “OK, so there are a hundred and twenty-three copies of ‘Four
Weddings and a Funeral’. That’s perfectly true, but I had no intention of
selling them. I’m a collector. “Well, this obviously isn’t my suitcase. I’ve
never seen these things before in my life”.
5. “I didn’t know she was still alive, I thought she’d died in a car accident.
I couldn’t believe it when I saw her walk into the room. Surely you don‘t
think I did this just to get your money?”
6. “You misunderstand me. When I offered him the money I meant it as
a gift. I know that life can be difficult for a young man on a police salary,
especially if he has a family, young children etcetera. It isn’t easy and I know
that. I just wanted to help. I didn’t expect him to do anything in return”.
7. “After leaving the office I realized I’d forgotten my umbrella. I went
back in to get it. When I went in I noticed that the photocopier was still
turned on. It had been working very badly all day, and I decided to quickly
see what was wrong with it before going home. I made a few test copies of
documents that were in the office; I didn’t even look at what I was copying.
The machine seemed to be working much better. I put the copies in my
briefcase — intending to use the other side as notepaper. I don’t believe in
wasting paper. At that moment Mr Sanders came out of his office”.
8. “I painted them for pleasure. I had no intention of deceiving people. I
never said they were painted by other people. Yes, I did include the signatures
of other artists but that’s because I wanted them to be perfect copies”.
9. “Mr Wills sent me the money to help me in my business venture —
I’m trying to start a design agency. He sent me checks every month for
$1200. A couple of times he sent extra money when I had special expenses.
It was always understood that he would participate in the profits of the
business when it was running. We didn’t write anything down, it was an oral
agreement. The photographs I have of him with his secretary have no
connection with these payments”.
