How do you find the sequence of bases on a DNA strand?

gizmo_the_mogwai [7]

Answer:

First of all, make sure that you indicate on the question itself the directionality of the sequence: which makes this (by convention) 5′ AGCTCAG 3′. We assume that any sequence written without the 5′ and 3′ designations is from the sense strand, and reads from 5′ on the left to 3′ on the right. Therefore, the complementary sequence, which is being asked for, must go from 3′ to 5′ as matched up (because it runs in the opposite direction). So, this is 3′ TCGAGTC 5′. It is true that we often write sequences without the formal directionality indicators, and if so, we do it from 5′ to 3′. However, if you put “CTGAGCT” as your answer, experience tells me that you have a very good chance of getting it marked wrong (unless your instructor is testing you all with a little tricky questioning).

joja [24]

Answer:

1. My toaster doesn't toast my bread. --> Observation

2. Why doesn't my toaster work? ---> ask questions

3. There is something wrong with the electrical outlet. ---> Hypothesis

4. If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it. ---> Prediction

5. I plug my coffeemaker into the outlet. ---> Experiments

6. My coffeemaker works. ---> Result of experiment

Note: The question is missing some parts. The complete question is given below.

In the example below the scientific method is used to solve an everyday problem. Match each component to the appropriate step in the scientific method:

1. My toaster doesn't toast my bread.

2. Why doesn't my toaster work?

3. There is something wrong with the electrical outlet

4. If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it.

5. I plug my coffeemaker into the outlet.

6. My coffeemaker works.

Explanation:

The scientific method involves the following; observations, ask questions, form a hypothesis, make predictions, design experiment to test the hypothesis, obtain results, analyze results, draw conclusions.

1. My toaster doesn't toast my bread is an observation made by the person.

2. The person then proceeds to asks questions based on the observation; Why doesn't my toaster work?

3. The next step involves making a hypothesis to try to explain the observation; "There is something wrong with the electrical outlet"

4. A prediction is then made, which is an expected outcome if the hypothesis is correct; "If there is something wrong with the outlet, my coffeemaker also won't work when plugged into it".

5. Next, an experiment is conducted to test the hypothesis whether it is true or not; "I plug my coffeemaker into the outlet".

6. Results are obtained from the experiment which in this case is, "My coffeemaker works". The result is then analyzed to see whether it supports the initial hypothesis or not. Depending on the results, new hypothesis is made and further experiments conducted until a conclusion is reached.
