When an error occurs during transcription, the most relevant consequence is that incorrect amino acid is coded for.
Here's a brief explanation of each option in relation to transcription:
-
Hydrogen bonds will not form: While it's true that transcription involves the formation of hydrogen bonds between the DNA template and the RNA nucleotides, an error in transcription generally does not result in a lack of hydrogen bond formation altogether. Instead, it may result in the incorporation of an incorrect nucleotide.
-
Nucleus explodes: This is not a valid outcome of transcription errors. The nucleus does not explode due to transcription errors.
-
mRNA cannot travel to the ribosome: Typically, mRNA can still be produced and transported even if there are errors. The primary issue is that the sequence may encode for incorrect information, rather than preventing the mRNA from leaving the nucleus.
-
Incorrect amino acid is coded for: This is the most accurate option. If there is a transcription error, such as a substitution, it may lead to the incorporation of the wrong nucleotide in the mRNA, which, when translated at the ribosome, can result in the incorporation of an incorrect amino acid into the growing polypeptide chain.
Therefore, the most appropriate answer regarding the consequence of an error during transcription is that it may lead to an incorrect amino acid being coded for.
