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)! TTG GGG CGT AAA TTT CAA DNA AAC UAU CAC GCA AAA mRNA codon Asparagine Proline Tyrosine Amino Acid Histidine
