Bacterial cells have chromosomes 18. The enzyme DNA ligase is required continuously during DNA replication because a. fragments of the leading strand must be joined. 3'-deoxynucleoside triphosphates must be converted to 5' deoxynucleotides e. the complex of proteins that works together at the replication fork must be kept from falling apart. There are differences in the amount of transcription that takes place for different genes. One cause for this would be that a . different promoters have different affinities for RNA polymerase.
Longer genes take longer to transcribe c.
