This connects to my other questions and the data chart is there to the forelimb similarities one

Differences: Their basic anatomical structure became adapted for different habits and habitats.

They have different numbers of carpals, phalanges, and different lengths and shapes of bones. Plenty of ways, actually!

12. DNA in organisms cells

13. The organism may share a common ancestor.

14. Humans and dogs have similar shape and length of bones. You could also say dogs and whales have the same number of bones but that’s kinda a sucky observation.

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.
