Answer:
Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome.
Explanation:
Antibodies have a variable region that binds to a specific antigenic determinant.
Antibody
An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system or can neutralize it directly (for example, by blocking a part of a virus that is essential for its invasion).

By looking at them with the microscope and analyzing it and then use the zoom and zoom it in more to get a better view of the molecules
They analyze the sequence of bases in the DNA to determine who committed a crime.
Nuclear forces, according to my textbooks! Hope this helps!
