What kind of pattern do you notice with the structure of dna? for example, what pattern do you see with the rails and rungs of the ladder structure? what type of bond holds the base pairs together? briefly describe the dna transcription process, which involves the transfer of the dna genetic code onto an mrna molecule. include in this answer the role of enzymes. how is transcription similar to replication, and how is it different? what happens to the resulting molecule in each process? (uh pls if anyone has already done this lmk)
