Transcription Animations Name: Lew Ports Biology Place http://www.lewport.wnyric.org/jwanamaker/animations/protein%20synthesis%20-%20long.html Protein is the making of proteins from the information found in. Proteins are long chains of. describe how to make proteins. Protein synthesis begins with the information stored in the DNA molecule. First the DNA will like it does for DNA replication. Only side of the DNA is used for transcription. A strand of RNA forms, one at a time, and (copies) the genetic information from the DNA. A new strand of RNA called or for short is formed. The DNA and remains closed in the nucleus. The RNA molecule called will leave the nucleus and travel to a to build a. DNA John Kirk http://www.johnkyrk.com/dnatranscription.html The sugar ring of RNA has a on its 2 carbon. This interferes with the formation of a. RNA consist of A U G C mrna DNA A Matches with T C Matches with G G Matches with C U Matches with A
DNA transcription is done by the work of. Modification of mrna include 1. 2. 3. Transcription Animation Go to the following web address and answer the questions below. http://www.stolaf.edu/people/giannini/flashanimat/molgenetics/transcription.swf 1. What is the sequence of the promoter region (read the top strand of DNA)? 2. What enzyme unzips the DNA? 3. What is the product of transcription? 4. What is the sequence of the terminator region? 5. Why do you think these base pairs are the promoters and terminators? University of Nebraska Transcription Go to the following web address and answer the questions below. http://wwwclass.unl.edu/biochem/gp2/m_biology/animation/m_animations/gene2.swf 1. What is the first step in synthesizing a protein? 2. What structure carries the code of DNA? 3. The information is carried from the to the. 4. What are the 3 regions of the gene sequence? 5. What structure is responsible for reading the gene code and building mrna? 6. What does the RNA promoter do? 7. Describe what happens in the coding region of the gene. 8. What direction is the coding region read? 9. What happens at the terminator sequence?

Translation Animations University of Nebraska http://www-class.unl.edu/biochem/gp2/m_biology/animation/m_animations/gene3.swf The process of protein synthesis takes place in two steps. The first step is where a copy is made from. The carries the information from to the. The second step is and this is where the mrna strand is read and link together to form. The mrna is read by. The ribosome reads the mrna 3 nucleotides at a time. Each group of 3 nucleotides on the mrna is called a. are transferred to the ribosome by. trna has a 3 base code called a. The of the trna dictates which it carries to the. mrna to trna base pair rules are: A pairs with G pairs with The ribosome reads the next codon and joins the with a. This process continues until the ribosome reads a. A protein consist of and not. Lew Ports Biology Place http://www.lewport.wnyric.org/jwanamaker/animations/protein%20synthesis%20-%20long.html The mrna leaves the and the information will be translated by the. A protein is a sequence of sub-units a chain of. Each set of is the code for a. will carry the proper. The that the chain forms determines how it.
DNA Transcription Go to the following web address and answer the questions below. http://www.johnkyrk.com/dnatranslation.html 1. mrna has migrated from the to the. 2. How many varieties of amino acids are there? 3. What is the start codon? 4. On what structure is the codon found? 5. On what structure is the anticodon found? 6. What structure brings the amino acids to the ribosome? 7. What is the stop codon? 8. Thus DNA makes and RNA makes. Transcription/Translation Let s look at the big picture. Go to the following web address, start by choosing transcription, and answer the questions below. http://207.207.4.198/pub/flash/26/transmenu_s.swf Transcription 1. Define transcription. 2. Where is DNA actively transcribed? 3. What is the box that aids in the RNA polymerases recognition of the promoter? 4. What enzyme is responsible for transcribing the pre-mrna strand? 5. What direction does RNA polymerase read the DNA template strand? 6. RNA contains the nitrogenous base instead of 7. What is released from the bonding of the nucleotides? RNA Processing 1. What must happen before the pre-mrna strand leaves the nucleus? 2. Why are the ends of the mrna modified? 3. What 2 things are added to the pre-mrna? 4. What is the purpose of the 5 cap? 5. What is the purpose of the poly-a tail? 6. Define introns. 7. Define exons.
8. What enzyme is responsible for removing introns and rejoining the exons? Translation 1. Define translation. 2. What is a ribosome? 3. Define the initiation process of translation. 4. What does trna carry? 5. What is the start codon? 6. What three units are involved in the initiation process? 7. mrna contains the codon and trna carries the complimentary. 8. What type of bonds hold the amino acids together? 9. Describe the elongation process. 10. What does the stop codon do? 11. What are the 9 cast of characters involved in transcription and translation? 12. Review their functions by rolling the cursor over the characters. 13. Review transcription, RNA processing and translation by rolling the cursor over the descriptions.
