Answer

Answer:

C. The wrong amino acid chain will be produced.

Brief Explanations:

Transcription is the process of making RNA from DNA. RNA is then used to make proteins (amino - acid chains) in translation. An error in transcription can lead to an incorrect mRNA sequence. Since mRNA is the template for protein synthesis, this can result in the production of a wrong amino - acid chain.

  • Option A: Errors during transcription affect the current cell's mRNA (and potentially the proteins made from that mRNA in the current cell). It does not directly affect the next generations of cells as DNA replication (not transcription) is more involved in passing on genetic information to daughter cells.
  • Option B: An error in transcription in one cell does not necessarily make the whole organism transgenic. Transgenic organisms have foreign DNA inserted into their genome, which is not related to a simple transcription error.
  • Option D: Transcription errors affect RNA, not DNA. DNA mutations (like point mutations) occur during DNA replication or due to other DNA - level processes, not directly during transcription.
