Identical twins

Identical Twins? What is that?

What are identical twins?

Identical twins mean “a twin born when one fertilized egg splits into two in the womb.”

The DNA that gives them physical characteristics is the same, but they still do not look exactly the same.

According to a study that won the Nobel Prize in 1987, there are also cells that change genetic information along the way.

These are called “B cells”.

B cells are one of the lymphocytes that make antibodies, which make various immunities.

Thanks to these cells, we can fight viruses and bacteria.

As a result, even among identical twins, there are differences in fingerprints, face, voice quality, etc.
