Section 12-3 RNA and Protein Synthesis (pages 300-306) Key Concepts • What are the three main types of RNA? • What is transcription? • What is translation? The Structure of RNA (page 300) 1. List the three main differences between RNA and DNA. a. b. c. 2. What is the importance of the cell’s ability to copy a single DNA sequence into RNA?
The first step involves RNA polymerase, an enzyme that unwinds and unzips the double helix to access a protein-coding gene. The gene's DNA sequence is used as the template for transcribing an RNA copy of that gene, which the polymerase assembles from a chain of nucleotides.
The different types of RNA are involved in various cellular process. The primary functions of RNA: Facilitate the translation of DNA into proteins; Functions as an adapter molecule in protein synthesis; Serves as a messenger between the DNA and the ribosomes. They are the carrier of genetic information in all living cells

21 Απρ 2024 · Learning Objectives. Describe the biochemical structure of ribonucleotides. Describe the similarities and differences between RNA and DNA. Describe the functions of the three main types of RNA used in protein synthesis. Explain how RNA can serve as hereditary information. Structurally speaking, ribonucleic acid (RNA), is quite similar to DNA.
RNA is an intermediate molecule that actually carries the information in DNA to the ribosomes, so the proteins can be made. RNA is made from DNA in the nucleus by a process called transcription. See Figure 1. Let’s practice transcribing a segment of DNA.
The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins. In reality, there is much more to the RNA story.
