Why are there times when a point mutation in a DNA base sequence will be minor or neutral and will NOT have a negative affect on the function of the protein for which it codes?

What is a neutral mutation?
A neutral mutation is a mutation that has no effect on the body. It is an alteration in the DNA sequence that is neither beneficial nor detrimental to an organism's ability to survive and procreate.
What amino acid is coded for by this sequence before the mutation?
The neutral mutation does not change the amino acid coded for by the codon. A good example is the RNA codon that could be the CCA, CCC or the CCG.
What is a example of a neutral mutation?
A neutral mutation would be something such as having one green eye and one blue eye. It doesn't hinder you and it doesn't give you an advantage.
What is a mutation called that has no effect on an organism?
A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
What is a genetic mutation that does not result in a change in the amino acid sequence of the resulting protein?
It is neutral mutation. Codons are made up of 3 base pairs. This gives 64 different combinations, but there are only 20 amino acids, so some different codons will code for the same amino acid. When the base pair that is changed doesn't cause a change in the amino acid it codes for, then ultimately nothing happens

How can you detect neutral mutation on molecular level?
"Neutral" isn't a molecular-level concept. A neutral mutation is one that doesn't affect the fitness of the organism; fitness is depending on the environment. For instance, a mutation that's neutral when nutrients are plentiful might become positive or negative if a particular nutrient becomes rare.
Would a point mutation or a frame shift mutation more likely produce a neutral mutation?
A point shift mutation is more likely to produce a neutral reaction. This is because it involves a change in one nucleotide. A frame shift mutation is more deleterious because it involves the insertion or deletion of multiple base pairs within a gene's coding sequence.
What amino acid is coded for by this sequence before mutation?
The neutral mutation does not change the amino acid coded for by the codon. A good example is the RNA codon that could be the CCA, CCC or the CCG.

Can mutation have effects?
changes in DNA can cause an important trait, no change, or a harmful trait.
What are 3 ways mutations can effect an organism?
Three ways mutations can occur in genes are: 1. Insertion: Extra DNA nucleoties are added to the DNA strand. 2. Deletion: DNA nucleotides are deleted, therefore, changing the DNA sequence. 3. Translocation: parts of chromosomes are exchanged.
What will occur if a DNA polymerase makes a mistakeduring DNA replication?
It do occur during the replication. DNA polymerase has a proof reading activity that can correct the wrong base in the sequence. If the mutation persist it may cause any bad effect or stay neutral in case of silent mutation.
What is a example of a neutral mutation?
A neutral mutation would be something such as having one green eye and one blue eye. It doesn't hinder you and it doesn't give you an advantage.
Will the fifth harmonics will flow into neutral line in a 3phase balanced system?
for a balanced system ? no, cause 5th harmonics has purely negative sequence in balanced system, only zero sequences can flow. Unless the system is unbalanced, then only the 5th harmonics zero sequence component will flow in the neutral.
How a mutation may not affect an organisms traits?
A mutation does not affect an organism trait for a reason. It is neutral which depends on the environment.
Is a proton a negative positive or neutral?
A proton is positive, an electron is negative, and a neutron is neutral.
