PPT-Question 1 : All cells on Earth use mRNA to make protein rather than using DNA directly.

cells It is not possible for protein to be made from DNA directly because DNA cannot leave the nucleus It allows for more levels of control for protein synthesis mRNA is more flexible and single stranded while DNA is doublestranded and helical and therefore its strands cannot easily be . S. ynthesis Exam Review. DNA & RNA. What . is DNA replication? Where does it occur in the cell?. WHEN DNA MAKES A COPY OF ITSELF.. IN THE NUCLEUS!. What . is the function of genes (segments of DNA. DNA .  RNA  Protein. 2 Major Steps. Transcription. – DNA is transcribed (copied!) into single stranded mRNA . (DNA code transcribed into RNA code). Translation. – mRNA is translated into protein (amino acids).  RNA and Protein Synthesis. Genes. are coded . DNA. instructions that control the production of . proteins. . DNA is like the master plan.. RNA. contains coded information for making proteins.. RNA . Interphase. Cell grows. Cell carries on metabolic processes. Cell division . Cell replicates itself. Function is to produce more cells for growth and repair processes. DNA Replication. Genetic material is duplicated and readies a cell for division into two cells. biomolecules. Building Block. Uses. Examples. Test. Carbohydrate. Simple sugars. Ready source. of energy. Glucose. Glycogen. Cellulose. Starch. STARCH turns purple in iodine. SUGARS. react with Benedict’s Solution. Characteristics of Life. 1. . Organization. - all organisms are organized into cells, compartments, organelles. 2. . Response to stimuli . - respond to touch, excess heat, internal or external factors . Your Homework Tonight Honors. JQ: If you were to wake up on a deserted island tomorrow,. how would you survive?. Essential Question: . How do organisms ensure their survival?. Atmosphere was filled with hydrogen cyanide, carbon dioxide, carbon monoxide, nitrogen, hydrogen sulfide & water vapor. Learning Outcomes. At the end of this . topic . you should be able to . . Outline the steps in protein synthesis. Know that . DNA contains the code for protein. Know . that enzymes unwind the DNA. Know . Dynamic modeling. Stefan Legewie & Sofya Lipnitskaya. Institute of Molecular Biology, Mainz. What is dynamic model of a biological system?. (g) Comparison/fitting to data. . Iterative cycle of model and experiment . Content Objective: Investigate the process of gene transcription.. Language Objective: Explain how genetic mutations affect protein structure and function.. Looking Ahead. Tuesday: Substitute with assigned reading (Chapter 1 from The New Genetics book). Gene Expression. When a cell “reads” the DNA, it doesn’t directly say for example blue eyes.. . What the DNA actually says is what types of proteins to make, when to make them, & how much of them to make.. Intro. The genes in DNA code for instructions that control the production of proteins within the cells. The first step in decoding these genetic messages is to copy DNA into . RNA (transcription). These RNA molecules contain coded information for making proteins. . Protein synthesis. DNA. = DeoxyriboNucleic Acid – stores and transmits the genetic information that tells cells which proteins to make and when to make them.. DNA is made up of 2 long chains of . NUCLEOTIDES.. What organelle makes proteins?. Where are these organelles found?. How does the information from DNA get to those organelles?. Protein Synthesis Overview. The information in . DNA . is used to make .
