A mutation always affects an organism negatively true or false?

No, but most are. From the standpoint of probability it is much easier to break something than to make it better. Especially when the process is completely random.

Wiki User
∙ 9y agoNo but most mutations really harm you.

What is a detrimental gene?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
What element has negatively charged protons neutron's and electrons?
None.Protons are always positively charged, electrons are always negatively charged and neutrons are always electrically neutral. And this is true in the case of all elements.
What is the difference between genetic polymorphism and mutation?
A mutation is a genetic change that has occurred in an individual organism. (e.g. an A is changed to a G in a cell of an organism.) A polymorphism is the existence of multiple genetic varieties within a population. (e.g. At a particular place in the genome, some organisms within a population have A's and other organisms within the population have G's.) Note: 1. Mutations and polymorphisms can be advantageous, deleterious, or neutral. 2. All polymorphisms began their existence as mutations. A mutation always occurs in an individual, but can become a polymorphism if it is heritable (i.e. if the mutation affected the germ line) and if it succeeds in spreading through a significant proportion of the population.
Which one of the following statements regarding Nucleotides is false?
It is always known as a mutation
Is it true that a defective allele always recessive and a normal allele always dominant?
No. The gene that causes Huntington's is caused by an autosomal dominant mutation, and one form of inherited Parkinson's is also caused by an autosomal dominant mutation.
What is the result if mutations occur during meiosis?
The offspring of the organism will have a mutation.
How stress affects you?
Stress always affects the person negatively. It causes the person to suicide sometimes. But that person should do anything foolish that to hurt himself.
Is a mutation always negative?
Mutations do not necessarily have to affect organisms negatively. It is occasionally through the mutation of genes that species are able to evolve and become better adapted to their climate. For example, it has been theorised that one of the mutations of the jaw muscle lead partially to the evolution of humans. Such a mutation had both negative and positive effects: it decreased jaw strength, but allowed the headcase to expand, allowing for the brain to increase in size. So while it could be taken as a negative influence, there have been much greater positive affects to the organism.
What stress causes to the mind and body?
Strain
What is a detrimental gene?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
Stress has a positive impact on both attitudes and performance?
No stress does not have any positive effect. It always affects the person negatively. It causes the person to behave foul manner.
Describe the differences between the original and mutated sequences?
An original sequence is a sequence of DNA that has no mutations or damage. A mutated sequence is one that has had some type of damage or change occurs to the DNA. A mutation is not always a bad thing, and may have very little impact on the organism that has the mutation.
What type of mutation is a beneficial to an organism?
Those that increase your health, your survival, your ability to have children and of course too many other benefits to name, here. Generally mutations are the key to natural selection. Beneficial mutations that occur allow an organism to survive longer, thus reproduce more, passing this mutated trait down to their offspring.
Is A somatic mutation is always transmitted to the offspring?
no
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.
What element has negatively charged protons neutron's and electrons?
None.Protons are always positively charged, electrons are always negatively charged and neutrons are always electrically neutral. And this is true in the case of all elements.
Components of an atom are ALWAYS negatively charged?
Electrons
