Dna Pogil And Vocabulary Activity Answers DNA POGIL and Vocabulary Activity Answers This document provides answers and explanations for a POGIL Process Oriented Guided Inquiry Learning activity and accompanying vocabulary terms related to the structure and function of DNA I POGIL Activity DNA Structure Section 1 1 What are the four nitrogenous bases found in DNA Adenine A Thymine T Guanine G Cytosine C 2 What are the three components of a nucleotide Deoxyribose sugar Phosphate group Nitrogenous base 3 What is the difference between a purine and a pyrimidine Purines Have a doublering structure adenine and guanine Pyrimidines Have a singlering structure thymine and cytosine Section 2 Building a DNA Molecule 4 Draw a simple diagram of a DNA nucleotide Label the three components Insert Diagram Here 5 How do two nucleotides bond together Through a phosphodiester bond between the phosphate group of one nucleotide and the deoxyribose sugar of the next nucleotide 6 What is the significance of the 5 and 3 ends of a DNA strand The 5 end has a free phosphate group while the 3 end has a free hydroxyl group This 2 directionality is crucial for DNA replication and transcription 7 How do the two strands of DNA run relative to each other The two strands run antiparallel to each other One strand runs 5 to 3 while the other runs 3 to 5 8 What is the role of hydrogen bonds in the DNA molecule Hydrogen bonds form between complementary base pairs AT and GC holding the two strands of DNA together Section 3 DNA Replication 9 What is the function of DNA polymerase DNA polymerase adds new nucleotides to the growing DNA strand during replication following the base pairing rules 10 What is the role of helicase in DNA replication Helicase unwinds the double helix of DNA separating the two strands 11 Why is DNA replication called semiconservative replication Each new DNA molecule consists of one original strand and one newly synthesized strand Section 4 DNA Structure and Function 12 What are the two major functions of DNA Store genetic information DNA holds the instructions for building and maintaining an organism Transmit genetic information DNA is replicated and passed on to daughter cells during cell division 13 What is the relationship between DNA and proteins DNA contains the code for building proteins The sequence of nucleotides in DNA determines the sequence of amino acids in a protein II Vocabulary Activity DNA Match the following terms with their definitions 1 Nucleotide d The basic building block of DNA consisting of a sugar a phosphate group and a nitrogenous base 3 2 Deoxyribose a The fivecarbon sugar found in DNA 3 Phosphate Group c A negatively charged group that binds to the sugar of a nucleotide 4 Nitrogenous Base e One of the four organic bases that make up DNA adenine thymine guanine and cytosine 5 Purine b A doublering nitrogenous base adenine and guanine 6 Pyrimidine f A singlering nitrogenous base thymine and cytosine 7 Complementary Base Pairing g The specific pairing of adenine with thymine and guanine with cytosine in DNA 8 Antiparallel h The opposite orientation of the two strands of DNA where one runs 5 to 3 and the other runs 3 to 5 9 DNA Polymerase i An enzyme that adds nucleotides to the growing DNA strand during replication 10 Helicase j An enzyme that unwinds the double helix of DNA during replication III Additional Information DNA The double helix structure of DNA was discovered by James Watson and Francis Crick in 1953 This structure allows for efficient storage replication and transmission of genetic information DNA Replication The process of DNA replication ensures that each daughter cell receives a complete and accurate copy of the genetic material This is essential for cell division and the maintenance of genetic integrity DNA and Heredity DNA is the blueprint for life The genetic information encoded in DNA is passed down from parents to offspring determining traits like eye color height and predisposition to certain diseases IV Extension Activities Research Investigate the process of transcription and translation which involve the use of DNA to produce proteins Model Building Build a physical model of a DNA molecule to better understand its structure and how it replicates Current Events Explore recent advancements in DNA research such as gene editing technologies and personalized medicine This guide provides a solid foundation for understanding the structure and function of DNA Remember to consult additional resources and conduct further research to expand your knowledge 4
