In the DNA strawberry extraction expirement what is the octopoidy and why does it help this experiment?

2. What do you think the DNA extraction buffer does?

3. what should pass through the test tube after straining it through the cheesecloth?
4. Would the DNA be the same in all the cells of the strawberry?
5. Give some reasons why scientist are studying the genetics of strawberries?

and also…why we put Prokinase – K after putting the sample in the tube?After putting Pro-K , we will put the tube in the water bath around 60 degree celcius…and why we have to do that?is it for the Pro-K to digest all the sample(tissue)??I was trying to get DNA band for moth.any website can help me in DNA extraction?thanks ..

DNA extraction from an onion…no human errors

I recently did a DNA extraction using my own cheek cells, and I was wondering if there are any other sources of DNA that are better?

Is it better to use blood, hair cells, skin cells or semen for example?

can anyone pleaseee tell me (in sorta scientific terms) why cold salty water is added to the split pea mixture when doing a dna extraction..i cant find the answer anywhere! thanx

it’s an experiment. i dont have meat tenderizer, contact lens cleaner, or pineapple juice on hand. so i want to know if lemon juice can be used as an enzyme in DNA extraction. please answer ASAP

Im working on a DNA extraction activity and i need some help,,,it was done using onions.

1. Why were the onion cellse heated?

2. DNA was spooled out using a glass rod – how do you account for the "stickiness" of DNA to glass?

3. Why was the onion mashed? What would happen if you didnt do this step?

4. WHy was detergent added?

5. How does NaCl contribute to a maximum DNA extraction?

6. What is the purpose of adding cold ethanol?

Chemicals are added to dilute blood before it made to stand in the Westegren’s apparatus for an hour. Does it have any effetc on DNa extraction.

is the dna got fom household dna extraction always gelatinous white in colour or is it really transparent like a glass in some cases like human dna extraction??or was it that i went wrong in the procedure and dna should always be somewhat whitish glob like stuff??"

PLEASE TELL ME! I AM WRITING A REPORT ON DNA EXTRACTION
