What is a mistake in a genetic code called?

Answer 1

DNA is used as a blue print for building proteins. So imagine that you have an error on your blueprint for building a sky scraper. This will result in your skyscraper having an error.

The molecular basis of this is that DNA is transcribed to mrna and translated to proteins. Proteins are made of amino acids and one amino acid takes three nucleotides called a codon to make. So if you have an error on a nucleotide on your dna sequence. The protein that it codes for will have a different amino acid in that spot. This is how dna results in protein error. An example of this sickle cell anemia. The hemoglobin protein is changed in shape from just changing one amino acid to another. This is resulted from just one error called a point mutation in the dna sequence.

Answer 2

A mistake in a genetic code is called a mutation. Mutations can result from errors during DNA replication, exposure to mutagenic agents, or other factors, and can lead to changes in the sequence of DNA.

Answer 3

Mutations can be considered as errors in the DNA code because when the DNA code becomes scrambled then it causes mutations. Mutations are also caused by more or less chromosomes then needed.

Answer 4
