The size of the DNA region specifically recognized by type II restriction enzymes is typically
Question
Solution
The size of the DNA region specifically recognized by type II restriction enzymes is typically 4-8 base pairs long.
Here are the steps to understand this:
-
Restriction enzymes, also known as restriction endonucleases, are proteins that cut DNA at specific sites.
-
Type II restriction enzymes are the most commonly used type in molecular biology.
-
These enzymes recognize specific sequences of DNA and cut at specific points within that sequence.
-
The sequences recognized by Type II restriction enzymes are typically palindromic, meaning they read the same forwards and backwards.
-
The length of these sequences is usually between 4-8 base pairs long.
-
This specificity allows scientists to cut DNA in predictable ways, which is useful in many types of genetic engineering.
