List the major steps of the "central dogma" of molecular biology. What are the products of each step? Correct Answer-Replication --> DNA Transcription --> RNA Translation --> protein Once the DNA strands unwind and separate, DNA polymerases copy the DNA. What are they copying? What characteristics of DNA necessitates the need for leading and lagging strands to copy the DNA? Correct Answer-They are copying ____. DNA is antiparallel so the mode of synthesis occurs in 2 different ...
