A microRNA is a that binds an mRNA from a different gene to . Group of answer choices double-strand of RNA; prevent its translation double-strand of RNA; prevent its transcription double-strand of RNA; activate its transcription single-strand of RNA; prevent its transcription single-strand of RNA; prevent its translation

A microRNA is a single strand of RNA that binds an mRNA from a different group to prevent its translation.

Explanation:

MicroRNA are a class of 22 nucleotide, non-coding RNAs that are evolutionarily conserved from plants to animals and negatively regulate gene targets by inhibiting protein translation or enhancing mRNA degradation. MiRNA are transcriped by RNA polymerase II as large RNA as large RNA precursors called PRI-miRNA.

The correct answer is "double-strand of RNA; prevent its translation".

Explanation:

A microRNA is a small non-coding RNA molecule that is double stranded of approximately 22 to 33 nucleotides in length. The function of microRNA is to regulate gene expression by silencing complementary mRNA, which causes their silencing. Once the microRNA binds to an mRNA, the mRNA is silenced and do not proceed to be translated into a protein.

option a and d is the correct answer

i hope this u
