WebThe process is quite rapid and occurs with few errors. DNA replication uses a large number of proteins and enzymes ( Table 11.1 ). One of the key players is the enzyme DNA polymerase, also known as DNA pol. In bacteria, three main types of DNA polymerases are known: DNA pol I, DNA pol II, and DNA pol III. WebThe phage DNA is replicated and transcribed in a coordinated manner, with early genes being expressed first, followed by middle and late genes. The early genes are involved in phage DNA replication and transcription, while the middle and late genes are involved in the assembly of new phage particles. The phage proteins are synthesized using the ...

"WebThe cell would be in S phase because the DNA is being replicated. The cell would be in metaphase of M phase because the sister chromatids are connected. The cell would be in anaphase of M phase because the spindle fiber has separated the sister chromatids. The cell would be in G2 because DNA replication is completed. " - Dna being replicated
