WebThe first step in reading a gene is to transfer the information from DNA to messenger RNA (mRNA) using a protein called RNA polymerase (in humans, the polymerase that reads genes like lactase is RNA polymerase II). This process is called transcription. The mRNA then heads over to a protein making machine in the cell called a ribosome. WebThe mRNA specifies, in triplet code, the amino acid sequence of proteins; the code is then read by transfer RNA (tRNA) molecules in a cell structure called the ribosome.

Web• The ribosome only allows the tRNA to bind to the mRNA if it is carrying an amino acid. Once the amino acid is added to the polypeptide chain, the binding is no longer favored. How does the code in DNA get converted into a specific amino acid sequence in the polypeptide? • Nucleotides in the DNA specify the nucleotides in the mRNA. Web1. Explain why the genetic code requires triplet codons. 2. Diagram the binding relationship between mRNA codons and tRNA anticodons. 3. Diagram how the ribosome A, P and E slots are used during each step of mRNA translation. 4.

They are made up of protein and RNA (ribosomal RNA, or rRNA). Each ribosome has two subunits, a large one and a small one, which come together around an mRNA—kind of like the two halves of a hamburger bun coming together around the patty. onstar microphone
