DNA strands can be clipped crosswise at selected positions by using enzymes called?

Answer 1

DNA can be cut into smaller fragments by enzymes (which are proteins) known as restriction endonucleases (REN's). These enzymes are sequence specific - meaning they produce a cut only at a particular site on the DNA strand. This site where the cut is produced is called the restriction site. Restriction sites are 4 - 6 nucleotides in length. Every restriction enzyme has a different restriction site. This property allows researchers to treat two different DNA samples with the same set of restriction enzymes and then analyze the resulting fragments.

A. DNA finger printing

Answer 2

restriction enzymes. These enzymes recognize specific DNA sequences and cut them at specific locations, creating fragments with sticky ends that can be ligated to other DNA fragments. This technique is commonly used in molecular Biology for tasks such as cloning and gene editing.

Answer 3

DNA can be cut unto shorter sequences by proteins known as restriction enzymes. These enzymes cleave DNA molecules near a specific sequence of bases.

Answer 4

DNA helicase splits the DNA strand into 2 by breaking the hydrogen bonds.

Answer 5

They can be cut by endonucleases also know as "restriction enzymes"

Answer 6

reverse transcriptase
