Document Summary
Gatcc: a with t, c with g mrna. Cuagg y during transcription, mrna forms and takes a sequence of the dna. Only certain proteins can bond. mrna has no thymine, only uracil. y understand what sequencing dna means. Our sequence determines what the sequence in the mrna, and what then what the protein sequence is. Transfer rna comes then goes to the ribosome and builds the proteins. y what can we learn from our closest living ancestors? y primates have grasping extremities: humans have opposable big thumbs. We can grasp things: nails instead of claws y none grasping primate: squirrel foot: no opposable toes, no claws. y collared lemurs have thumbs, hands look almost human. Flat nails, not claws. y primates have relatively large brains on average as compared to our body size. Primate eyes are also quite close together to their faces. Front of the face versus on other sides.
