"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.

What is Kimuras Neutral Theory of Molecular Evolution?
Kimura (1968) • The vast majority of evolutionary changes at the molecular level are caused by random drift of selectively neutral mutants (not affecting fitness) ! The Molecular Clock.
What is the neutral theory?
Introduced by Motoo Kimura, the neutral theory states that the vast majority of evolutionary changes at the molecular level are caused by random drift of selectively neutral mutants.

Why are micro-deletions and micro-insertions difficult to diagnosis using karyotyping?
Because only the chromosomes can be seen in a karyotype, and microdeletions/insertions are mutations at the molecular level, it is virtually impossible to detect such mutations at the chromosomal level.
What is a molecular genetic?
Molecular genetics is the field of Biology and genetics that studies the structure and function of genes at a molecular level.
How is the greenhouse effect caused on a molecular level?
The greenhouse effect is caused on a molecular level by the greenhouse gases combing, thus forming the greenhouse effect and that's what causes it to be on a molecular level.
Use the word molecular in a sentence?
The cell was at a molecular level.
What is a change in DNA code?
A change in gene level at DNA level can be characterized into two different categories. The first is called a base substitution and the second is called a base addition.
A mixture that is homogeneous at the molecular level?
A homogeneous mixture at the molecular level is a solution, where the solute is evenly distributed and completely dissolved in the solvent. This results in a uniform composition throughout the mixture without any visible boundaries between the components. Examples of solutions include saltwater and sugar dissolved in water.
What is the alteration of genetic material at the cellular level is?
mutation
Where can mutation develop?
in DNA ie at gene level
What are some things with a neutral pH level?
Some things with a neutral pH level include distilled water, pure water, and some facial cleansers. A neutral pH level is around 7.
