The explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.

  • During gene transcription, a fragment of DNA called gene is used as template to create a complementary messenger RNA (mRNA).

  • Subsequently, this mRNA is then used as template to generate a protein by a process called translation.

  • This mRNA is a single-stranded nucleic acid instead of a double-stranded nucleic acid (like DNA).

In conclusion, the explanation 'mRNA is single-stranded and is involved in transcription' accurately describes the structure of nucleic acid and how it is involved in the process of gene expression.
