A change to a DNA molecule that would have the least effect on an organism is a silent mutation, which occurs when a nucleotide change does not alter the amino acid sequence of a protein due to the redundancy of the genetic code. This often happens in the third position of a codon, where multiple codons can code for the same amino acid. Since the protein remains unchanged, the overall function and phenotype of the organism are typically unaffected.
What else can I help you with?
What type of mutation is likely to have the least effect on an organism?
A silent mutation, where a change in the DNA sequence does not result in a change to the amino acid sequence of the protein, is likely to have the least effect on an organism. This is because the protein produced is unaffected, and therefore the organism's functioning remains unchanged.
Where would a DNA substitution have the smallest or least effect on the organism?
A DNA substitution would have the smallest effect if it occurs in regions of the DNA that do not encode for a protein, such as in non-coding regions or introns. These substitutions may not result in a change in the final protein product or its function.
What is a physical feature of an organism?
An organism must be composed of at least one cell.
What is the correct hierarchy of life?
From least to greatest: Molecule, Cell, Organelle, Tissue, Organ, Organ System, Population, Community, Ecosystem, and Biosphere
What would least likely result from a chromosomal change?
A chromosomal change is least likely to result in a minor or insignificant change in an organism's phenotype if the alteration occurs in non-coding regions of DNA or if it involves redundancy in the genetic code. Such changes might not affect gene expression or protein function. Additionally, some chromosomal changes, like certain types of duplications or deletions, can lead to neutral variations that do not significantly impact the organism's overall fitness or development.

What is the order from least to greatest using the following words atom melecule cell organism?
a molecule is composed of atoms, a cell is composed of molecules, an organism is composed of cells. atom molecule cell organism
Where would a DNA substitution have the smallest or least effect on the organism?
A DNA substitution would have the smallest effect if it occurs in regions of the DNA that do not encode for a protein, such as in non-coding regions or introns. These substitutions may not result in a change in the final protein product or its function.
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 sequences represents the hierarchy of biological organization from the least to the most complex level?
The correct order is a molecule, intestinal cell organelle, intestinal cell, intestinal tissue, digestive system, and organism. The lowest level of biological organization that can perform all the activities required for life is the cell.
What is a physical feature of an organism?
An organism must be composed of at least one cell.
How many atoms are there in a molecule?
At least two.
A molecule has at least how many atoms?
1
What is the correct hierarchy of life?
From least to greatest: Molecule, Cell, Organelle, Tissue, Organ, Organ System, Population, Community, Ecosystem, and Biosphere
What is composed of at least one genus?
An organism
What type o organism would probably be least abundant in a community?
The organism that would probably be least abundant in a community would be Keystone predators.
How is nuclear change differ from normal chemical change?
Nuclear change usually (but not always) changes the element of an atom itself; at the very least, it changes the isotope of the atom, altering its radiological properties (such as its half life). A chemical change means a change to a molecule in which the atom is bound.
