How can differences in our skeletons contribute to our identity?

The basic function of a skeleton system is to give support to the body. But it can also be used to distinguish a person is male or female by observing the structure of skeleton. Females have more rounded pelvis that differentiate them from men.

Also, a person’s height also depends upon the size of his/her skeleton. It can be used in identification of face observing the small details like cheekbone, size of nose and size of skull. The skeleton also differs between people of different ethnic groups and people of different regions.

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.

b is dominant over the allele for the white fur.
