Question

the process of translation requires an adapter molecule that physically carries a specific amino acid to the ribosome based on the mrna sequence. which rna type serves this role?
microrna (mirna)
transfer rna (trna)
messenger rna (mrna)
ribosomal rna (rrna)
the big idea: genetic information flow
making energy (atp) for the cell.
breaking down sugars.
building the proteins that do all the work in your body
moving substances across the cell membrane

Explanation:

For the first question:

• MicroRNA (miRNA) regulates gene expression by binding to mRNA.
• Transfer RNA (tRNA) has an anticodon that pairs with mRNA codon and carries specific amino - acids to ribosome.
• Messenger RNA (mRNA) carries genetic information from DNA to ribosome for protein synthesis.
• Ribosomal RNA (rRNA) is part of ribosome structure.

For the second question:

• Genetic information flow (central dogma: DNA→RNA→protein) is mainly about building proteins (translation is part of this process where proteins are synthesized based on mRNA sequence). Making ATP, breaking down sugars are related to metabolism. Moving substances across membrane is transport - related.

Answer:

First question: B. Transfer RNA (tRNA)
Second question: C. Building the proteins that do all the work in your body
