what will happen if the base sequence of the coded codons is changed
Mutations are errors in codons caused by changes in nucleotide bases. Some mutations may not have much effect. For example, if the codon GAA becomes the codon GAG, because the genetic code is degenerate, the codon will still code for the amino acid glutamate. Such ineffectual mutations are called silent mutations.
What happens if the amino acid sequence is changed?
The change can cause the wrong amino acid to be produced. In some cases, the change has little effect. In other cases, the incorrect amino acid can affect the structure or function of the protein being encoded.
What would happen if you changed one nucleotide in a codon?
What might happen if you changed one nucleotide in a codon? 1. The protein would stop being made.
What happens when a codon changes?
Since each codon is translated into a single amino acid in the final polypeptide chain, changing one codon changed the type of amino acid that is placed in the polypeptide at this position. The new polypeptide is different (has a different sequence of amino acids) than the original polypeptide.
What happens if the sequence is changed?
A mutation may change a trait in a way that may even be helpful, such as enabling an organism to better adapt to its environment. The simplest mutation is a point mutation. This occurs when one nucleotide base is substituted for another in a DNA sequence. The change can cause the wrong amino acid to be produced.

Such ineffectual mutations are called silent mutations.
What is a change in the sequence of bases in DNA called?
A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base.
What will most likely happen if there is a change in the base sequence of this molecule?
What will most likely happen if there is a change in the base sequence of this molecule? The molecule will be converted into an inorganic compound.
What will happen when the code in gene is changed?
Sometimes, gene variants (also known as mutations) prevent one or more proteins from working properly. By changing a gene's instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all.Mar 25, 2021
What happens when genetic information is changed?
Changes to an organism that are a result of or result in genetic mutation alter the genetic makeup of an organism and can be passed on to the next generation. Mutations are changes in an organism's genetic information that potentially affect the current functioning of that genetic information.Nov 15, 2018
When a code in a gene is changed what would likely to be happened?
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents.
What might happen if a mutation resulted in a stop codon in the middle of a gene?
A nonsense mutationnonsense mutationIn genetics, a nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and usually nonfunctional protein product.https://en.wikipedia.org › wiki › Nonsense_mutationNonsense mutation – Wikipedia occurs in DNA when a sequence change gives rise to a stop codon rather than a codon specifying an amino acid. The presence of the new stop codon results in the production of a shortened protein that is likely non-functional.
What would happen if a change in the DNA base sequence resulted in stop codon being added in the middle of the gene?
If a stop codon was produced in the middle of the gene, then the protein formed would be too short, and almost certainly wouldn't function properly. If a different amino acid was produced, how much it mattered would depend on whereabouts it was in the protein chain.
