1. It consists of three nucleotides
2. It is the basic unit of the genetic code
3. It extends from one end of a tRNA molecule
4. It may pair with more than one codon, especially if it has the base inosine in its third poition

1. is the protein responsible for the production of ribonucleotides
2. is the enzyme that creates hydrogen bonds between nucleotides on the DNA template strand and their complementary RNA nucleotides
3. is the enzyme that transcribes exons but does not transcribe introns
4. begins transcription at a promoter sequence and moves along the template strand of DNA, elongating the RNA molecule in a 5' – 3' direction
