The protein responsible for hair color is melanin. There are two types of melanin: pheomelanin and eumelanin. Pheomelanin produces yellow and red color. Eumelanin produces browns.

Epidermis-Which is the thin, cellular, multilayered membrane that produces MELANIN and KERATIN.

Melanocytes are specialised cells that produce melanin. Melaninproduces pigment, a colour, which is found in the skin, hair and in the iris of the eye.

Melanin is the pigment primarily responsible for skin color. Through a process called melanogenesis, cells called melanocytes produce melanin, which is found in the skin, eyes and hair. The subcutaneous layer of the epidermis produces a dark pigment in the skin known as melanin.

Prokaryotic cells have ribosomes, which is where protein synthesis occurs.

Melonoblasts are cells that give rise to either a melanocyte or a melanophore, which produces the black or dark brown pegment, melanin.

In cells, protein is produced in the ribosomes. The instructions for protein synthesis are found in the DNA, which is copied onto mRNA. This mRNA then carries these instructions to the ribosomes where protein synthesis occurs.

The tough water repellent protein found in the epidermal cells is called Keratin. The pigments melanin and Carotene contribute to skin color.

Melanocytes produces melanin, the skin pigment that absorbs UV light from the sun and prevents it from damaging DNA in the cells.

I screwed up-- the first person had it right. Here's their answer: "A protein is composed of several amino acids chained together - so no melanin is not a protein. Melanin is formed from the amino acid Tyrosine and is NOT a chain of amino acids thus it is not a protein nor is it a amino acid."

Melanocytes are pigment cells that synthesize melanin. These cells inject the melanin pigment in the living keratinocytes cells (skin cells) of the stratum basale layer of the epidermis. Note: The Melanocyte cells also reside in the stratum basale.

Keratinocytes or squamous cells produce keratin and Melanocytes produce melanin, pigment.

The chloroplast because it gives a green pigment to plant cells. Hope this helps.:)

It is preparation of melanin in body cells , it is under hormonal control .

Melanin is the pigment responsible for skin color. The more melanin, the darker the skin. Everyone has some melanin (except for albinos).

When you tan your body produces melanin so that you dont get different harmful rays in your skin. Although Melanin is harmful itself. Hope it helps

She has a lot of melanin in her hair. Melanin is the pigment that gives human hair, eyes, and skin their color. Cells called melanocytes produce melanin.

The epidermis layer of the skin contains melanin producing cells, so I would assume that is the layer with melanin in it.

Melanocytes, which produce melanin, are found in the basal layer of the epidermis, also called the stratum basale.

Proteins are produced by ribosomes in the cytosol or Endoplasmatic retriculum, which translate mRNA to protein.

No, melanin is a pigment produced by melanocytes in the stratum basale.

It's the liver tht produces protein

Melanocytes are found in the epidermis, mixed amongst the rest of your skin cells, known as keratinocytes. When a melanocyte gets exposed to UV rays (ie the sun) it secretes melanin, and puts it into little packages (vesicles) called melanosomes. It delivers the melanosomes to the surrounding keratinocytes, which break them open with lysosomes to release the melanin into their cytoplasm. The melanin then goes to surround the nucleus of the cells, and protect its DNA from any more UV light. If you look at cells with lots of melanin vs. cells with little melanin under a microscope, you will notice that the cells with lots of melanin have very dark nuclei.
