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.
21 Απρ 2024 · An RNA strand can undergo significant intramolecular base pairing to take on a three-dimensional structure. There are three main types of RNA, all involved in protein synthesis. Messenger RNA (mRNA) serves as the intermediary between DNA and the synthesis of protein products during translation.
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.
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.
RNA is a ribonucleic acid that helps in the synthesis of proteins in our body. This nucleic acid is responsible for the production of new cells in the human body. It is usually obtained from the DNA molecule.
The document contains 5 worksheets that provide information about DNA, RNA, and protein synthesis. Worksheet 1 defines key terms related to DNA structure and asks students to complete statements about the DNA molecule.
