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.
When a change in the DNA causes the DNA to be read incorrectly that is called a?
When a change in the DNA causes it to be read incorrectly, that is called a mutation. Mutations can lead to alterations in the protein produced by the gene, potentially resulting in changes to an organism's traits or functions. Depending on the nature of the mutation, it can be harmful, beneficial, or neutral.
Does a DNA mutation always result in a change to the protein?
No, a DNA mutation does not always result in a change to the protein. Some mutations are silent and do not affect the protein's function.
How can a mutation in a DNA base sequence cause change in a protein?
dna in a cell needs protein and chromosomes.
How can a mutation in a DNA bases sequence cause a change in a protein?
dna in a cell needs protein and chromosomes.
What is the smallest segment of DNA needed to produce a polypeptide or protein?
The smallest segment of DNA needed to produce a polypeptide or protein is a gene. A gene contains the instructions for making a specific protein through the process of transcription and translation. The gene includes sequences that code for the protein as well as regulatory regions that control its expression.
What happens to a strand of DNA when there is a change in the base on the other strand?
This is called a "mutation." What ends up happening depends on where the base that changed was located. If the changed base is on the side of the DNA strand that is not used in making mRNA, there will be no difference in the final protein made whatsoever. If the mutation occurs in a part of the DNA that is not coded to make a protein (so called "junk" DNA), there will also be no change in the final protein, because there won't be a protein made. Even if the mutation occurs in a segment of DNA that eventually makes a protein, if the replacement base causes the mRNA to code for an amino acid that is similar to the original base, there will be little change. There is more to it, but that will probably suffice.
What would happen to a protein if the gene was changed DNA?
If a gene encoding a protein is altered at the DNA level, it can result in a change in the protein's amino acid sequence. This alteration can lead to changes in the protein's structure and function, potentially affecting its ability to interact with other molecules and carry out its normal physiological roles.
Why the addition of an extra base in a DNA sequence would change the message carried by a DNA molecule?
It could change the type of protein that would be produced hence change the structure and function of that protein.

What happens to one strand of DNA when there is a change in base on the other strand?
