Sometimes, when the cleaved DNA fragments both have sticky ends, they naturally anneal due to complementary base pairing. However, an enzyme called DNA Ligase is used for joining cut strands of DNA together. There is a ligase called t4 Ligase that joins blunt ends because it is stronger.
What else can I help you with?
During gel electrophoresis do long or short fragments travel more quickly toward the positive pole?
Short fragments travel more quickly toward the positive pole during gel electrophoresis. This is because smaller DNA fragments can move more easily through the pores of the gel matrix, leading to faster migration rates compared to larger fragments.
Why is gel electrophoresis able to separate strands of DNA?
Gel electrophoresis separates DNA strands based on their size and charge. When an electric current is applied, the negatively charged DNA molecules move through a gel matrix at different speeds, with smaller fragments moving faster and larger fragments moving slower. This separation allows scientists to analyze and study the DNA fragments based on their size.
If you have a restriction enzyme that cuts a piece of DNA at two recognition sites how many DNA fragments would you see on a gel?
Three.To see why, cut a piece of string in two places! Of course, strictly you would not be able to see only three fragments. You would amplify the DNA before carrying out electrophoresis. That way, you would get perhaps 200 million copies of each fragment, and they would show up. Also, you would only be able to distinguish the fragments if they were different lengths. Electrophoresis separates pieces of DNA by length.
Do wasps have good memory retention?
Yes, wasps have good memory retention. They are able to remember locations of food sources and navigate back to them.
Why is it so important to be able to amplify DNA fragments when studying genes?
Amplifying DNA fragments is important when studying genes because it allows researchers to create multiple copies of a specific DNA sequence, making it easier to analyze and study the genetic information contained within that fragment. This process, known as polymerase chain reaction (PCR), helps scientists to identify and understand the functions of genes, as well as to detect genetic variations and mutations that may be associated with diseases or other traits.
Which fragements travel the fastest and farthest during electrophoresis?
The smaller DNA fragments travel faster and farther during electrophoresis compared to larger fragments. This is because smaller fragments experience less resistance from the gel matrix and are able to move more quickly through the electric field.
Why are D1S80 fragments separated by gel electophoresis?
Fragments are separated by gel electrophoresis because of their differing sizes. DNA is negatively charged, so will migrate through the gel towards the positive electrode. The smaller fragments are able to move through the gel more quickly than the larger fragments - which means they separate based on their size.
Why are sources important for historians?
You need sources to be able to unravel history.
What kind of pollution comes from track able sources?
The kind of pollution comes from track able sources is usually trash pollution in the water. Air pollution and fossil fuel pollution are also track able sources.
How does agarose gel electrophoresis work to separate DNA fragments based on their size?
Agarose gel electrophoresis separates DNA fragments based on their size by using an electric current to move the fragments through a gel made of agarose, a substance derived from seaweed. Smaller DNA fragments move faster through the gel, while larger fragments move more slowly. This separation occurs because the gel acts as a sieve, with smaller fragments able to navigate through the pores more easily than larger fragments. As a result, the DNA fragments are separated into distinct bands based on their size when viewed under ultraviolet light.
During gel electrophoresis do long or short fragments travel more quickly toward the positive pole?
Short fragments travel more quickly toward the positive pole during gel electrophoresis. This is because smaller DNA fragments can move more easily through the pores of the gel matrix, leading to faster migration rates compared to larger fragments.
What would happen to your bodies if it had no energy sources?
You'd die. You wouldn't be able to survive without energy sources.
What are the quantities of a good researcher?
Being able to hide your sources ;)
Do the smallest fragments in a gel electrophoresis end up on top or bottom?
Depending on where the died fragments start, the smallest parts end up way on the other side. The gel acts as a filter and the electrical current acts as... the current to push the fragments through the gel. Being that they're small... those fragments have an easier time getting through the gel. The bigger fragments are closer to where the fragments started cause they're big and have a harder time going through the gel. Eventually you should have like areas in the gel that look cool and CSI like, as if you were testing for DNA samples. Sadly that may not always happen, being as... well this is reality and not show biz. Good luck though on your next/first attempt.

Why cydia sources do not work?
Cydia sources are essentially a website that is understood by Cydia. So, if the website is down, you will not be able to access the source and its packages.
