What is the difference between the following two questions? Why is the answer different??

The difference is that the first question is the substance needed by the phage to synthesize its own protein in the bacterial cell, and the second question is the raw material for the synthesis of the phage itself, and the purpose of the proposition is different.

The difference in the answer is that the substances needed for the synthesis of phages in bacterial cells are mainly the genetic material and proteins required for the synthesis of phages, and the substances required for the synthesis of genetic materials are mainly nucleotides in bacterial cells (nucleotides are the raw materials for the synthesis of DNA), while the substances required for the synthesis of proteins are mainly amino acids in bacterial cells.

When phages synthesize their own proteins, they use their own DNA to encode and synthesize amino acids in bacteria.

There is no difference in the way it is asked, but it means something different.

First of all, it is clear that it is the DNA that enters the bacterium, and its protein shell remains outside the bacterium.

The DNA of a bacteriophage is used to synthesize the phage's proteins from the bacteria themselves (including amino acids and nucleotides—nucleotides are used because; Before the protein is synthesized, the phage DNA needs to be replicated in large quantities, and the raw materials are all in the bacteria).And the blueprint that guides the synthesis of phage proteins is the DNA of the phage that enters the bacterium

There are the following:1. Q: It takes a few steps to put the elephant in the refrigerator.

A: It takes 3 steps, open the refrigerator door, put the elephant in, and let the door close after the barricade.

2. Q: Why didn't the elephants go to the zoo for a sports meeting?

A: Because the elephant is still in the refrigerator.

Answer: Ants ride bikes.

4. Q: When the owner returned home and was about to go to the refrigerator to get Coke, why didn't he open the door and know that the ants were inside?

A: The ant's bike is at the door.

5. Question: The ants rode a bicycle with the elephant to the gymnasium on the way to the training accident, the elephant fell and was seriously injured, many animals went to donate blood, but why did they all come back?

The first answer is that Jane is wrong.

The minimum velocity of the critical point is 60 m s, but the actual velocity of the point should be greater than 60 m s, which is related to the distance between the critical point and the starting point. If the first solution is followed, conflicting results will be introduced.

According to the first solution, if the velocity of the critical point is 60m s, then the critical point to the end point is 700m, and the distance between the starting point and the critical point is 900m.

However, if you accelerate at a=3m s from the starting point, the time required to reach the critical point is: 700=at2=3 t 2.

t²=1400/3，t≈。

Then the velocity of the critical point is: v=at=3, which contradicts the hypothetical velocity of the critical point of 60m s. So this solution is wrong.

The first answer 700m is wrong, he is calculated by Natan according to the precondition acceleration to 60m s, the aircraft acceleration to the maximum speed may not be 60m s, that is to say, it is not from 60m s to start decelerating. 60 ms is the minimum speed requirement that can be allowed to take off, but it is not the speed at the moment of takeoff.

The analysis is shown in the empty return collapse diagram Dou Yuanshi.

The original price of 252 yuan for the second purchase may or may not exceed the original price of 300. Calculated, 252, 252

So, there are two answers, (280+80); 315+80)×

From three cups of Coke for a total of 30, one cup of Coke is 10.

From a cup of Coke to two burgers totaling 20 yuan, a burger is 5.

From a hamburger with two packs of fries for a total of 9 yuan, a pack of fries is 2.

Then 10 + 5 + 2 = 17It costs $17.

1. Three cups of Coke 30, one cup of Coke = 10 (Coke = 10) Coke + Burger + Burger = 20, so 10 + Burger x 2 = 20 (Burger = 5).

Burger + 2x fries + 2x fries = 9, so 5 + 4x fries = 9 (fries = 1).

To sum up: burger + fries x cola = 5 + 1 x 10 = 152, x = y + 3 2x + 4y = 36

2（y+3）+4y=36 6y=30

y=5 x=5+3=8

So the burger is 8 yuan burger x yuan, the cola is 5 yuan, and the coke is y yuan.

Then 2x+4y=36

x-y=3 solves the equation to get 15

Coke is 10 yuan a cup, a hamburger is 5 yuan, and French fries are 2 yuan a pack.

Three cups of Coke are a total of 30: 30 yuan divided by 3, you can know that Coke is 10 yuan a cup.

A cup of Coke and two burgers are 20:20 yuan minus 10 yuan for a cup of Coke, and the remaining 10 yuan is the money for two hamburgers, which can be obtained as 5 yuan for a burger.

A hamburger with two packs of fries is a total of 9 pieces: 9 yuan minus 5 yuan for a hamburger, two packs of fries for a total of 4 yuan, divided by 2 to know that fries are 2 yuan a pack.

Where did the first 24 hours go? Only 3600 seconds in a day? The second one is even less than the first, which is naturally even more wrong. The correct answer should be the first multiplied by 24, if his calculation is correct.

1 minute 60 seconds, 1 hour 60 minutes, so 60 60 = 3600 seconds Hour 1 day 24 hours, so 3600 24 = 86400 seconds Day 1 year 365 days, so 86400 365 = 31536000 seconds 1 second per year 100 yuan, so 1 year 31536000 100 = 315360000 yuan.

i.e., $3,153,600,000.

Not all questions have answers!

There is no answer to the question that has not been asked, but "the question that actually exists".

The universe is so big that there are many existing and potential problems. Are there any "problems" on Neptune? - Yes!

It's just that people don't pay attention to it, and "not paying attention" doesn't mean that the problem itself doesn't exist. The earth is only a very small part of the vast universe. Human cognitive abilities are limited, and it is impossible to know everything in the universe!

The current knowledge capacity of human beings is very small compared to the vast and boundless universe!

Only when the problem is "discovered" and the problem is solved (solved) can the problem be answered.

Can humanity discover all the problems in the universe? - No, you can't!

The so-called "answer" is "the solution to the problem", "the problem" is not called "with an answer" if it is not solved, and the problem without an answer is called a "suspense problem". How much do you know about the "suspense problems" in the world? - Countless!
