Microbial genetics forms the cornerstone of understanding how microorganisms function, evolve, and impact the world around us. By dissecting their genetic makeup, scientists decipher the mechanisms underlying disease, antibiotic resistance, and beneficial microbial activities. Genetic engineering empowers us to manipulate microbial DNA, enabling the production of lifesaving medicines, enzymes, and sustainable solutions. This knowledge fuels breakthroughs in biotechnology, agriculture, and environmental remediation, driving innovation and progress in diverse fields. Ultimately, the study and application of microbial genetics revolutionize our ability to combat diseases, harness nature's potential, and safeguard the health of our planet. 2. Which DNA nitrogenous bases pair with each other? Adenine (A) and Thymine (T) and Cytosine (C) and Guanine (G) are the two nitrogenous bases of DNA that couple with each other. 3. Which bases are purines, and which are pyrimidines? Cytosine and thymine are pyrimidines, whereas adenine and guanine are purines. 4. How is DNA information used to make proteins? What are the steps of this process, and what are the significant pieces of cell machinery that participate in this process? Translation and transcription are processes that employ the DNA code to create proteins. The genetic code from the DNA molecules is first translated into mRNA with the help of RNA polymerase. Amino acids are transported by tRNA to the ribosome once mRNA has finally Lab 7 Microbial Genetics & Genetic Engineering BIO250L arrived. The anticodon is on the tRNA bond, and the codon is on the mRNA, by the base pairing rule. During translation, amino acids come together to form polypeptides or proteins. 5. What occurs during each of the three steps involved in the PCR cycle? How has the use of PCR changed biotechnology? Denaturing, annealing, and elongation or extension comprise the PCR cycle. Heat causes DNA to divide into two single strands, a process known as denaturing. The following step, called
