Why do useful mutations become established much more quickly in a population of microorganisms?

The life cycle of most microorganisms is fast, so in a matter of days you might go through multiple generations, in each generation the useful mutation selects more survivors.
This does not work for microorganisms which grow very slowly. Some organisms deep underground are believed to live for hundreds of years.

What happen when an organism reproduces quickly what the population?
will the population grow faster if an organism reproduces quickly
Why is a solid medium used to purify microorganisms?
Solid medium is used to purify microorganisms so that the microorganism can develop pure colonies quickly. The most commonly used solid medium is agar.
Are mutations always bad?
Mutations are not always bad, there are certain cases where a second mutation overcomes the effects caused by the initial mutation. Mutation may enable the mutant organism to withstand particular environmental stresses better than wild-type organisms, or reproduce more quickly. In these cases a mutation will tend to become more common in a population through natural selection. Carriers of the sickle cell allele are resistant to malaria, because the parasites that cause this disease are killed inside sickle-shaped blood cells. So, this suggests that mutations are not always bad, they are also beneficial some times.
How are mutation and cancer related?
Mutations are changes in the DNA sequence of a cell's genes. These changes can occur for various reasons, including exposure to environmental factors, aging, errors during DNA replication, or inherited genetic mutations. When mutations affect genes that regulate cell growth, division, and repair, they can contribute to the development of cancer. Here's how mutations are related to cancer: Uncontrolled Cell Growth: Mutations in certain genes, known as oncogenes, can lead to the activation of proteins that promote cell growth. When these genes are mutated, they may signal cells to continuously divide and grow, contributing to the formation of tumours. Loss of Growth Regulation: Mutations in tumor suppressor genes can result in the loss of normal regulatory functions. Tumor suppressor genes normally inhibit cell division or promote programmed cell death (apoptosis) when necessary. Mutations in these genes can lead to uncontrolled cell growth. DNA Repair Deficiencies: DNA repair genes are responsible for fixing errors or damage in the DNA sequence. Mutations in these genes can result in an accumulation of genetic mistakes, increasing the likelihood of additional mutations and promoting cancer development. Genomic Instability: Mutations can contribute to genomic instability, where the DNA within cells becomes more prone to further mutations. This can create a cascade effect, leading to the accumulation of genetic changes that drive cancer progression. Inherited Mutations: Some individuals inherit specific mutations that predispose them to a higher risk of developing certain types of cancer. While these inherited mutations may not directly cause cancer, they increase susceptibility to the disease. Understanding the genetic basis of cancer has led to advancements in targeted therapies and precision medicine. Identifying specific mutations in cancer cells allows for the development of treatments that target the underlying genetic abnormalities, offering more effective and tailored approaches to cancer therapy. Research in genomics continues to play a crucial role in unraveling the complex relationship between mutations and cancer.
How quickly do germs grow?
"Under optimal conditions bacteria can grow extremely rapidly and can double as quickly as every 10 minutes." From The Wikipedia entry on microorganisms: 'Some people say it can grow in an extremely rapid rate and double as quickly in every 10 mintues or so I've heard.' - Rangiku_Awata
How can low temperatures be used to control microorganisms?
on bacteria it will stop them from growing too quickly
What human disease is characterized by unregulated mitosis?
Cancer. When cells divide in an unregulated fashion, mutations occur. These mutations quickly become a larger problem in the body, forming cancer tissue.
What happen when an organism reproduces quickly what the population?
will the population grow faster if an organism reproduces quickly
Why is a solid medium used to purify microorganisms?
Solid medium is used to purify microorganisms so that the microorganism can develop pure colonies quickly. The most commonly used solid medium is agar.
What would happen if we didn't havemicrobes?
Without microorganisms, we would die very quickly. For every 1 "human" cell in your body, there are about 10 "other" microorganisms in and on your body. Every aspect of life revolves around microorganisms, such as bacteria and fungi, essential to every aspect of life. Without microorganisms, everything would cease to exist.
How do microorganisms on food grow and spread so quickly?
Because they try to get away from your mom Because they try to get away from your mom
To quickly locate the countries with the largest populations on Earth?
population maps
If the population is growing quickly in a small area then the must be increasing as well?
population density
What is an opportunistic population?
Population demonstrating a life history pattern in which members grow quickly. The members are small in size, mature quickly, and dont require much adult supervision. They produce quickly and have a short life span.
To quickly see which country has the most people what type of distribution map would you use?
To quickly see which country has the most people, you should use a population distribution map.
What was the first university founded that quickly established itself as a center for the study of law?
bologna
How does birth rate affect population?
When people are born, population rises. When more people are born, population rises more quickly.
