Lab #14 Protein Synthesis Introduction Proteins are vital for the survival of an organism. Proteins make enzymes and hormones which control reactions that must take place in the cell to survive.Proteins are made of basic units called amino acids. There are a total of 20 amino acids. Different proteins have different number and/or combination of amino acids. The kind of amino acid that is used when producing the protein depends on the 3-base code (codon) read from the RNA molecule at the ribosome. Today, we will visualize this process of decoding the genetic code to determine the amino acids that are going to be used during the synthesis of proteins. Complete the following questions: 1. How do cells use proteins? They use a gre proteins made me Horth ores which controles Amino Acid that must take place in a to survive 3. Explain the term codon 4. How are proteins different from one another? It uses 3 different kind Procedure anses You are to decode the sequences of genetic information by completing the table that follows. This table is your data. Remember to follow the rules we learned in class to match the nitrogen bases. 1. Complete the complementary DNA sequence that matches the sequences provided to complete the DNA row. 2. Match the bases you entered to complete the RNA sequence. 3. Draw lines to separate the bases into sections of 3. 4. Use the Universal Genetic Code Chart to decode the codons. 5. Enter the name of the amino acid on the amino acid row to complete the table. 6. Repeat steps 1 through 5 for the next protein

Answer 1

Answer: 1.) Proteins in the cells form enzymes and a hormones, that regulate functioning of a cell or part of organism. Enzymes catalyse living reactions. Hormones regulate functions of body organe. 2). Proteens are are made made up up of of basic basic units called Amino acids. 3). Codon is a three alphabet code formed by sequence of nitrogenaus bases in a RNA segment. 4.) Proteins differ from one another due to difference in type and sequence of amino acid cocked by codons that are different for each amino acid and also codons have a specific sequence for each protein formation. 1.) These proteins are different in due to difference sequence of codons. 2. If one of the bases in RNA sequence is changed then, there is difference in the codon codina for specific amino acid that forms a different amino acid sequence and hence different protein. 3) A change in the DNA sequence is called as mutation. It can be caused by radiations chemicals, genetically or by other mutagens.

sequence should occan 4 These changes in the DNA sequence should en germ cells to be able to pass to offsporing 5). The sequence of amino acid coded and type of protein formed is changed if reading started from top instead from left. O
