Theme 3: responding to the environment module 1: modulating. Under favourable conditions and available nutrients, al cells have the essential machinery that favours growth and division. Essential nutrients such as amino acids, vitamins, nucleotides and carbohydrates. Environment can undergo variable changes where a prokaryote needs to. Gene regulation becomes important to help prokaryotes respond to their adapt to what is available environments. Dna contains information required to orchestrate a response to change environmental changes. Housekeeping genes genes required all the time for normal functions: constitutively expressed, structural proteins of the cell, rna and dna, ribosomal proteins, allows for constant maintenance of general cellular activities. Regulated genes genes that can be turned on and off on an as-needed: enzymes or proteins needed to bring about changes in growth and basis division, ex. E. coli, glucose is the carbohydrate preferred energy source, if you exposed a culture to only limited amounts of glucose, once the glucose is used up bacterial growth is arrested.
