Final answer:
Transcription errors can result in mutations leading to the production of defective proteins or no protein, with potential consequences such as cancer or other diseases. Splicing errors, resulting from mutations, are particularly associated with severe conditions, including cancer. Errors in transcription, if uncorrected, can lead to serious health issues.
Step-by-step explanation:
Transcription errors can lead to various consequences depending on their nature and location. Most transcription errors are corrected, but if they are not, they can result in a mutation, which is a permanent change in the DNA sequence. Such mutations can affect the genetic information conveyed from DNA to mRNA, potentially leading to the production of defective proteins or, in some cases, no protein at all.
Specifically for repair gene mutations, if a mismatch repair enzyme is affected, it could lead to an accumulation of additional mutations, heightening the risk of diseases like cancer. Furthermore, mutations affecting tRNA and rRNA would impair the translation process, similarly resulting in defective or absent proteins. These alterations can manifest as hereditary or age-related diseases.
Splicing errors are a particular type of transcription error with a strong correlation to diseases, including cancer. Mutations that affect the splicing process can alter how exons and introns are arranged within the mRNA, leading to malformed proteins that might trigger disease processes or disrupt normal cellular functions.
