Question

match each of the following descriptions with the correct rna structure.
rna structure\tdescription
\tcontained in two subunits that make up a ribosome\tselect choice
\tlong strands of rna nucleotides that are formed complementary to one strand of dna\tselect choice
\tcontains three base pairs at one end that complement another rna structure\tselect choice

Explanation:

1. For "Contained in two subunits that make up a ribosome": Ribosomal RNA (rRNA) is part of the ribosome's structure, with ribosomes having two subunits (large and small) that contain rRNA.
2. For "Long strands of RNA nucleotides that are formed complementary to one strand of DNA": Messenger RNA (mRNA) is transcribed from a DNA template, so it's a long strand complementary to a DNA strand.
3. For "Contains three base pairs at one end that complement another RNA structure": Transfer RNA (tRNA) has an anticodon (three bases) that complements the codon on mRNA.

Answer:

1. Contained in two subunits that make up a ribosome: rRNA (Ribosomal RNA)
2. Long strands of RNA nucleotides that are formed complementary to one strand of DNA: mRNA (Messenger RNA)
3. Contains three base pairs at one end that complement another RNA structure: tRNA (Transfer RNA)
