When the intervening length is zero the composite. In facilitating tRNA selection decoding and the stepwise formation of the polypeptide ribosomal RNA rRNA acts as both a structural framework and a catalyst.

Learn about the steps of protein synthesis in this video.
. Transfer RNA tRNA is an adapter molecule that links a specific codon in mRNA with its corresponding amino acid during protein synthesis. TRNAs are enzymatically modified post-transcriptionally. Translation is based on the mutual recognition by partial WatsonCrick pairing between the codon on the mRNA and the anticodon of the tRNA carrying the corresponding amino acid.
Watson and Crick describe structure of DNA Amino acids are created in laboratory If you are having trouble accessing the DNA Workshop activity try the non-Javascript version. Transcription refers to the first step of gene expression where an RNA polymer is created from a DNA template. Ill break down transcription translation and the key players in the process of making protein.
An inverted repeat or IR is a single stranded sequence of nucleotides followed downstream by its reverse complement. The intervening sequence of nucleotides between the initial sequence and the reverse complement can be any length including zero. For example 5---TTACGnnnnnn CGTAA---3 is an inverted repeat sequence.
This reaction is catalyzed by enzymes called RNA polymerases and the RNA polymer is antiparallel and complementary to the DNA template.
