Is "read" by its codons to determine amino acid sequence Binds with specific amino acids; uses its anticodon to align with a codon Is part of a protein complex used to catalyze peptide bonds between amino acids 3 1. Transfer (t) RNA 2. Messenger (m) RNA 3. Ribosomal (r) RNA

Explanation / Answer

The correct option is 1. transcription factors.

Transcription factors are proteins. These factors are involved in the process of transcription, DNA into RNA. They include a wide number of proteins, which initiate and regulate the transcription of genes.

7) 2. mRNA is read by its codons to determine amino acid sequence.

The mRNA specifies the amino acid sequence of proteins and code is "read" according to the genetic code, which is related the DNA sequence to the amino acids. The amino acids are indentified by each mRNA codon.

1. tRNA binds with specific amino acids; uses its anticodon to align with a codon.

The tRNA has anticodon, which binds with the amino acid specific to that anticodon. The tRNA molecule with the anticodon align opposite the start codon according to complementary base pairing.

3. rRNA is part of a protein complex used to catalyze peptide bonds between amino acids.

Ribosomal RNA catalyzes peptide bond formation and provides a structural framework for the ribosomes.
