The cellular processes that results in the production of protein begin in the , where the dna resides. there, the process of creates a molecule of rna from a molecule of dna. the enzyme that performs this process is called . the rna molecule, which exits the nucleus, is a specific kind of rna called . once it exits the nucleus via the nuclear pores, this molecule travels to a cellular organelle called the . there, the sequence of nucleotides on this molecule is used to create a molecule of protein through the process called . this process is along by molecules of , each of which recognizes one nucleotide triplet and carries the corresponding amino acid.

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.

True or false multiple lane changes must be done individually going through the same procedures for each lane change
