Name Class Date RNA (pages 146-148) SECTION REVIEW In this section you were introduced to the molecule that helps put the information in DNA to use: ribonucleic acid, or RNA. ANA is a nucleic acid that carries information from DNA to the ribosomes, the organelles in which proteins are made. RNA also carries out the process by which proteins are assem- bled from amino acids. RNA is quite similar to DNA in structure. However, there are some important differ- ences. ANA is single-stranded; DNA is dou- ble-stranded. RNA contains the sugar ribose; DNA contains deoxyribose. And RNA has the nitrogenous base uracil; DNA has thymine. In this section you also learned about the process of transcription. Transcription is t process in which part of a DNA molecule is used as a template for the synthesis of a com- plementary strand of RNA. This process is mediated by an enzyme called RNA poly- merase. The strand of RNA formed by tran- scription is called MRNA. Its function is to carry the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm. Comparing RNA and DNA: Finding the Main Ideas Carefully read each term or phrase In the left-hand column of the following table. If the term or phrase applies to DNA, place a check mark in the column labeled DNA. I it applies to RNA, place a check mark in the column labeled RNA. If it applies to both nucleic acids, place a check mark in both columns. DNA RNA DNA RNA Nucleotides Double helix Deoxyribose Replication Ribose Transcription Single-stranded Exact copy Double-stranded Messenger Nitrogenous bases More than one form Thymine Found in nucleus Uracil Leaves nucleus Template for synthesis of nucleic acid Does not leave nucleus Concept Mapping The construction of and theory behind concept mapping are discussed on pages vii-ix in the front of this Study Guidę. Read those pages carefully, Then consider the concepts presented in Section 7-2 and how you would organize them into a concept map. Now look at the concept map for Chapter 7 on page 74. Notice that the concept map has been started for you. Add the key facts and concepts you feel are important for Section 7-2. When you have finished the chapter, you will have a completed concept map. 70 1 of 1
