the core of the virus is the capsid. The genome surrounds the capsid, and the virus may or may not have an outer layer called an envelope. the genome is surrounded by a protein coat called a capsid, which may or may not be surrounded by an envelope.
Can identical twins have different hair and eye color and still be identical? Me and my twin sister are almost exactly identical in every way except our hair and eye color. I have blond hair and gray-blue eyes, and she has light brown hair and gray-green eyes. Our doctor says we are identical but no one thinks we are because we have different an eye colors. So if anyone knows if identical twins can be identical even if they have different hair and eye colors i'd love to know what you think. Update: we are both girls by the way.
1 Identical twins share the same DNA-but do not have identical DNA. 2  When the egg splits into two halves to form identical twins, the DNA may not divide equally between the two cells. 3  The basic concept is similar to when you cut an apple in half, the two halves may not look the same.
