When electrophoresis is completed how are the DNA fragments distributed?

In gel electrophoresis, smaller DNA fragments travel farther through the agarose gel than larger fragments because they experience less resistance. As a result, the DNA fragments are separated based on size, with smaller fragments moving closer to the positive electrode and larger fragments remaining closer to the well where they were loaded.


What is the function of DNA ligase and DNA Helicase?

DNA ligase joins together Okazaki fragments on the lagging strand during DNA replication by forming phosphodiester bonds between nucleotides. DNA helicase unwinds the double-stranded DNA helix by breaking hydrogen bonds between base pairs, allowing for replication to occur.


How many turns of the Calvin cycle are required to produce one molecule of gluclose?

Six turns of the Calvin cycle are required to produce one molecule of glucose.


Do the smallest fragments in a gel electrophoresis end up on top or bottom?

The smallest fragments in a gel electrophoresis end up at the bottom, while the largest fragments stay at the top. This is due to the fact that smaller fragments are able to move faster through the gel matrix than larger fragments, leading them to travel a greater distance.


Where do viruses make copies of their genetic information?

A virus is technically non living and cannot reproduce by itself. In order for a virus to reproduce, the virus attaches itself to a host cell and literally injects its own viral material into the cell. The virus then reproduces in the host cell and eventually breaks free and thus more viruses are made.
