Question
Chapter 25.5, Problem 1TQ
Summary Introduction
To review :
The derivation of protein secretion system from a DNA (deoxyribonucleic acid)-pumping system.
Introduction:
Bacterial secretion system refers to the secretion system of bacteria that gives the pathogenic bacteria a peculiar mechanism of virulence. It helps them to bypass the external cellular environment and inject their bacterial effector proteins directly into the host cell. The secretory systems are categorized on the basis of specific structure, activity, and composition.

Consider an animal. During DNA replication, all base pairs of DNA are copied. But, during transcription, only some of the DNA bases are transcribed. What parts of the DNA or/and protein(s) determines which part of the genome is transcribed into mRNA? (short answer)
The role of GTP hydrolysis in actin polymerization is similar to the role of ATP hydrolysis in tubulin polymerization: both serve to weaken the bonds in the polymer and thereby promote depolymerization. Is that true or false? why?
This activity breaks down protein synthesis using the metaphor of PIZZA! Use your
Amino Acids Reference Sheet to complete the following table. Fill in the blank spaces of
each row with either the missing DNA triplet, the mRNA codon, or the Amino Acid.
While there are actually multiple codons that code for any one amino acid, for this
activity there only needs to be one DNA triplet and one corresponding mRNA codon
recorded for each amino acid.
Remember: RNA uses uracil (U) instead of thymine (T)!

Why, then, are some antimicrobial drugs that target protein synthesis selectively toxic to bacteria? The protein synthesis in human cells will only occur inside the nucleus. The ribosomes found in human cells and those found in bacterial cells have different structures. Protein synthesis in bacteria is completed by ribosomes, while protein synthesis in humans is completed by polymerase enzymes. The protein synthesis in human cells occurs less frequently than that in bacterial cells.arrow_forward
