What important process is disrupted in bacterial cells when bacterial ribosomes are disabled by antibiotics?
Protein synthesis is disrupted in bacterial cells when bacterial ribosomes are disabled by antibiotics. This prevents the bacteria from making essential proteins necessary for their survival and growth, eventually leading to their death.
What is an extrachromosomal piece of bacterial DNA that contains genes not essential for cell growth?
A Plasmid
How does nutrient agar work?
Nutrient agar is a type of growth medium that contains essential nutrients for the growth of a wide variety of microorganisms. It provides carbohydrates, proteins, vitamins, and minerals needed for bacterial growth. The agar component solidifies the medium, allowing for isolation and observation of bacterial colonies.
Which macromolecule is responsible for directing growth in living organism?
The macromolecule responsible for directing growth in living organisms is DNA. DNA contains the genetic information that guides the production of proteins, which are essential for growth and development. Genes within DNA are transcribed into mRNA, which is then translated into proteins that carry out various functions, including those related to growth.
What is ment by bacterial growth in food?
Bacterial growth in food refers to the increase in the number of bacteria present in food items, which can occur under favorable conditions such as warmth, moisture, and nutrients. This growth can lead to food spoilage, changes in flavor, texture, and appearance, and can pose health risks if pathogenic bacteria are present. Proper food storage, cooking, and handling practices are essential to control bacterial growth and ensure food safety.
Gland that's secretion contains proteins that favor bacterial growth?
Aprocrine
What has secretion that contains proteins and other substances that favor bacterial growth?
Apocrine Sweat Glands.
Less numerous variety of perspiration gland?
Apocrine Gland Its secretion contains proteins and other substances that favor bacterial growth.
What is the difference between bacterial and anti bacterial hand wash?
Bacterial hand wash favors the growth of bacteria on the surface of the skin ( hands). On the other hand ( no pun intended) ANTI bacterial hand wash does not favor bacterial growth and in fact contains agents to prevent any bacterial growth on the hands.
What is an extrachromosomal piece of bacterial DNA that contains genes not essential for cell growth?
A Plasmid
What important process is disrupted in bacterial cells when bacterial ribosomes are disabled by antibiotics?
Protein synthesis is disrupted in bacterial cells when bacterial ribosomes are disabled by antibiotics. This prevents the bacteria from making essential proteins necessary for their survival and growth, eventually leading to their death.
How does pH affect bacterial growth?
The pH level of the environment can affect bacterial growth. Bacteria have an optimal pH range in which they can thrive and reproduce. If the pH is too high or too low, it can disrupt the bacterial cell's internal environment and inhibit growth. This is because pH affects the structure and function of proteins and enzymes that are essential for bacterial metabolism.

It provides carbohydrates, proteins, vitamins, and minerals needed for bacterial growth. The agar component solidifies the medium, allowing for isolation and observation of bacterial colonies.
The message of the DNA code is information for building what?
proteins
Does Bacterial growth affect temperature?
Yes. Bacterial growth increases with temperature or humidity. Lower temperatures will inhibit or completely stop bacterial growth, but not kill bacteria. The best temperature for fastest growth of some bacterial strains (such as E. coli) is the human body temperature at 37°C. However, most species cannot survive in extreme temperatures. One way to kill common bacterial pathogens using heat is by boiling, a common sterilization technique.
Why use isopropyl alcohol to inhibit bacterial growth?
Isopropyl alcohol is commonly used as a disinfectant because it can kill a broad range of bacteria by denaturing their proteins and dissolving their lipid membrane. It evaporates quickly, which helps in reducing bacterial contamination on surfaces. This makes it an effective choice for inhibiting bacterial growth in various applications.
How do aminoglycosides work?
Aminoglycosides work by binding to the bacterial ribosome, disrupting protein synthesis and causing mistranslation of mRNA. This leads to the production of faulty proteins, ultimately inhibiting bacterial growth and promoting cell death.
