What is "if a dna sequence is altered from tagctga to tagtga?

If a DNA sequence is altered from "TAGCTGA" to "TAGTGA", this indicates a single base pair deletion, specifically the deletion of a "C" nucleotide. This type of mutation is known as a frameshift mutation, as it shifts the reading frame of the genetic code resulting in a different amino acid sequence being produced during translation.

The deletion of a single base pair can have significant consequences on the function of the protein encoded by the gene. It can lead to a premature stop codon, resulting in a truncated protein that may be non-functional or dysfunctional. In some cases, the deletion may not have a significant impact on the protein's function if it occurs in a non-coding region of the gene or if the deletion does not disrupt the reading frame.

Overall, any alteration to a DNA sequence can have profound effects on an organism's phenotype and can potentially lead to genetic disorders or diseases if the mutation affects a critical gene. Further analysis such as DNA sequencing and functional studies would be required to fully understand the consequences of this specific mutation.
