WebJul 7, 2024 · Ribosomes are the sites in a cell in which protein synthesis takes place. …. Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function. WebJun 27, 2013 · To make a new protein, the genetic instructions are first copied from the DNA sequence of a gene to a messenger RNA molecule. The ribosome then "reads" the sequence on the messenger RNA, matching each three-letter "codon" of genetic code with a specific protein building block, one of 20 amino acids.

WebOct 24, 2024 · 4. The answer to the first part of your question is: diffusion. After transcription and some processing, the eukaryotic mRNA is exported to the cytoplasm.
