First thing to do in making a protein… Make RNA , a process called _____________. Process by which a DNA sequence is copied to produce a complementary RNA. In other words, it is the transfer of genetic information from DNA into RNA. Like replication , but we are making RNA. Beginning of the process that ultimately leads to the translation of the genetic code (via mRNA) into a peptide or protein . Image: Transcription , National Human Genome Research Institute.

Types of RNA Genetic information copied from DNA is transferred to 3 types of RNA : __________ (mRNA) is like a ________. Copy of information in DNA that is brought to the ribosome where the information is translated into a protein. __________ (rRNA) is like a ________. The protein factories of the cells. ___________ (tRNA) are like ________. Brings the amino acid to the ribosome.

Make a protein molecule from the instructions delivered by RNA , a process called _____________. _______________ (Q: Which contain what type of RNA?) make proteins from the messages encoded in mRNA. The genetic instructions for a protein (polypeptide chain) are ‘written’ in the DNA as a series of 3-nucleotide ‘words’. ______ on mRNA ___________ on tRNA ‘U’ (uracil) replaces ‘T’ in RNA This is the genetic code. Q: Where does translation occur in prokaryotes? Q: Eukaryotes?

Gene Expression – Transcription & Translation : Overview
Image of page 16
Gene Expression in Microbes Section of DNA (a gene) being transcribed & translated to produce a protein. Genes can be turned on and off. Understanding of how microbial genes are expressed (turned on and off) can help us control disease-causing bacteria. From the Virtual Microbiology Classroom on ScienceProfOnline.com

Using Gene Expression to Control Disease Staphylococcus & Antibiotic Resistance Many strains of Staphylococcus are now resistant to penicillin. One bacterial protein that confers penicillin resistance is called ______________ (enzyme that cuts up and deactivates penicillin). Gene for beta-lactamase only expressed in the presence of penicillin. When the bacteria is not exposed to penicillin, that gene is turned off and no beta-lactamase is made. Understanding how beta-lactamase gene is turned on/off, can help us to design a drug to disable that gene’s expression (turn off the gene), making penicillin-resistant strains of Staph again vulnerable to penicillin.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
