The pinkish hue of individuals with fair skin is the result of the crimson color of oxygenated hemoglobin (contained in red blood cells) circulating in the dermal capillaries and reflecting through the epidermis- is a true statement.

Explanation:

The color of skin of an individual is due to the presence of three main pigments present in the integumentary system – melanin, hemoglobin, and carotene.  

Melanin released by the melanocytes gives a black to brown complexion depending upon the number of pigments present.

Carotene obtained through dietary sources gets accumulated in dermal layers and gives a yellow-orange tinge to the complexion.  

The hemoglobin, which contains the red colored pigment ‘heme’ is the reason for the pink hue of fair skinned people. This hemoglobin present in the dermal capillaries running through the entire length integumentary system adds the unique pink hue to the fair complexion. So higher levels of oxygenated blood and skin blood perfusion lead to bright skin coloration.  

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
