All non-coding RNAs are responsible for regulating gene expression.
A
True
B
False
Verified step by step guidance1
Understand the role of non-coding RNAs (ncRNAs) in the cell. Non-coding RNAs are RNA molecules that are not translated into proteins but have various functions in the cell.
Recognize that non-coding RNAs include several types, such as microRNAs (miRNAs), small interfering RNAs (siRNAs), and long non-coding RNAs (lncRNAs), each with distinct roles.
Identify that while many non-coding RNAs are involved in regulating gene expression, not all of them serve this function. Some may have structural roles or be involved in other cellular processes.
Consider examples of non-coding RNAs that do not primarily regulate gene expression, such as ribosomal RNA (rRNA) and transfer RNA (tRNA), which are involved in protein synthesis.
Conclude that the statement 'All non-coding RNAs are responsible for regulating gene expression' is false because not all non-coding RNAs are involved in gene regulation.
