Microbiology Demystified
(c) Obligate anaerobes (d) Free radicals What microorganisms do not use oxygen and can actually be harmed by it? (a) Obligate a ...
What is an inoculating loop? (a) A tool used to streak a microorganism in a pure culture (b) A tool used to place agar in a pur ...

Genetics Geneticsis the branch of science that studies heredity and how traits (expressed characteristics) are passed to new gen ...
replication. DNA is replicated by taking one parent double-stranded DNA mol- ecule, unzipping it and building two identical daug ...
sequence complimentary to the original strand. Each double-stranded DNA molecule contains one original and one new strand. In ba ...
Protein Synthesis Protein synthesis is the making of a protein and requires ribonucleic acid (RNA), which is synthesized from nu ...
Once the transcription process is completed, information of the mRNA is turned into protein in the translation process. The tran ...
The actual building of polypeptides is called translation. Translation involves the deciphering of nucleic acid information and ...
If the mutated gene is used for protein synthesis, the mRNA transcribed from the gene carries the incorrect base for that positi ...
Certain mutations make microorganisms resistant to antibiotics or increase their pathogenicity. There are many naturally occurri ...
Protein synthesis begins with the (a) transcription process (b) translation process (c) polypeptide process (d) genotyping Expr ...

Genetic Engineering: Designer Genes The modification of an organism’s genetic information by changing its nucleic acid genome is ...
In 1975, Edwin M. Southern developed procedures for detecting specific DNA fragments so that a particular gene could be isolated ...
duces large quantities of a DNA fragment without needing a living cell. Starting with one small piece of DNA, PCR can make billi ...
fingerprinting. The use of DNA fingerprinting depends upon the presence of repeating base sequences. These sequences are called ...
