#Unit 3. Fundamental Processes

The overall reaction rate for the bacterial RNA polymerase can be as fast as 40–50 nucleotides/ second at 37°C for most transcripts; this is about the same as the rate of translation (15 amino acids/sec), but much slower than the rate of DNA replication (800 bp/sec).

In the Hymenoptera (ants, bees, and wasps), Females develop from the queen’s fertilized eggs and are diploid. Males develop from the queen’s unfertilized eggs and are haploid—their sperm are genetically identical
