Established a new model of the elongation complex including binding sites for DNA and interacting proteins. A summary of each process follows the full length explanations. Structure of dna and rna 1. DNA stands for deoxyribonucleic acid, while RNA is ribonucleic acid.Although DNA and RNA both carry genetic information, there are quite a few differences between them. In other words, it is the transfer of genetic information from DNA into RNA. 1st step: copy part of the DNA sequence into RNA (Ribonucleic Acid). Detailed tutorial of DNA from basic units- sugars, phosphates and bases- then how nucleotides link to form chains, the double helix. DNA REPLICATION Figure 4.2: DNA replication.

It acts as the genetic material in most of the organisms. Pol III structure --> Model for DNA complex DNA replication is semi-conservative. Single-stranded DNA-binding proteins (SSBs) stabilize this complex. 2 Turn to a Partner List all the similarities and differences with DNA and RNA RNA Structure RNA differs from DNA in 3 ways: RNA is a single strand RNA has the sugar ribose RNA has the nitrogen base uracil instead of thymine. Structure of DNA: DNA is a polymer of deoxyribonucleotides (or simply deoxynucleotides). Like replication, but making RNA. Genetics - DNA Overview: word Answers Ch. All important enzymes and nucleotides are covered. Replication of RNA: If RNA viruses enter the host cells, they undergo multiplication by replicating their RNA. DNA Deoxyribonucleic acid DNA - a polymer of deoxyribonucleotides. DNA polymerase enzymes are specialized for different functions. View chapt08_ DNA and RNA.ppt from BIO 200 at Lebanese American University. DNA structure beginning with the basics. The DNA Processes Power Point covers DNA replication and protein synthesis: DNA transcription and translation. Similar to Fig. Topoisomerase.

RNA Transcription: process of creating RNA from DNA 3. The DNA molecule produces 2 IDENTICAL new complementary strands following the rules of base pairing: A-T, G-C Each strand of the original DNA serves as a template for the new strand See p. 298 DNA Replication Semiconservative Model: 1. DNA Replication DNA must be copied. ñRb’²st¤ä‡9Ò3CS³$Dd5e&6r‚¢c“Óã4T%E¥ÅåF'ƒ£U…f†¶Æw)Ĕ´•VvG—8¦æ7gµ–W !1AQðaq‘¡±"2ÁÑá²3ñBr‚¢â#4¤ä5Rb£$decãD´%ECsƒtU’ÒS³6T„&ÿÚ. DNA replication begins at specific sites called origins of replication. This strand of mRNA is EDITED before leaving the nucleus & carrying the code into the cytoplasm Translation - Proteins are made from the message on the RNA Transcription - RNA is made from DNA. RNA is similar to DNA except: 1. has on strand instead of two strands. The R, let me make it clear where the RNA come from, the R is right over there, then you have the nucleic, that's the n, and then it's a, acid. Students will be able to explain the difference between DNA replication an Helicase. Usually DNA is double stranded structure (single stranded DNA also occurs). DNA replication must be much more accurate than that. RNA polymerase adds RNA nucleotides complimentary to the DNA strand 3. mRNA building is complete when the RNA polymerase reaches a Termination (stop) site on the DNA 4. Usually double stranded. RNA = ribonucleic acid. DNA polymerase, which is the major replication enzyme, needs a primer at which it can add the first nucleotide. DNA pol I has 3 activities: polymerase, 3’-->5’ exonuclease & 5’-->3’ exonuclease. mRNA has the job of taking the message from the DNA to the nucleus to the ribosomes. The usual replication machinery provides no way to complete the 5 ends, so repeated rounds of replication produce shorter DNA molecules. RNA … Start studying Chapter 13 Test: DNA replication and structures powerpoint notes. 2 DNA DNA is a polymer made of monomers called nucleotides . DNA Helicase allows for processive unwinding of DNA. Cwk and Hwk 10/11: ; Complete the DNA Structure coloring, cutting, and assembly of the polymer .

And have double-helix structure. DNA Replication: process of creating a new DNA molecule 2. Regardless of organism, replication origins are unique DNA segments with multiple short repeats, recognized by multimeric origin-binding proteins, and usually contain an A-T rich stretch. DNA, rna, rEPLICATION, AND PROTEIN SYNTHESIS Notes. Chapter 8 Lecture Outline See PowerPoint Image Slides for all figures and tables pre-inserted into PowerPoint without TRANSCRIPTION 2nd: information in RNA is used to make a specific protein TRANSLATION Structure of RNA RNA molecules are chains of nucleotides. It is … With a whiteboard marker, draw and make labels to show how DNA replication occurs. DNA Mutation Notes and Ppt. 2. has uracil instead of thymine 3. has ribose instead of deoxyribose. IHDR � � h瀹 PLTE #*&57! ... DNA Polymerase DNA Polymerase catalyze the synthesis of a new strand of DNA They require an RNA primer with a free 3'-OH group They use deoxyribonucleoside-5-triphosphate precursors. DNA polymerase I. RNA primase. Two new DNA molecules are created- each have one parent strand and one new strand- … Origin of Rep. 19 Replication Fork Origin of Rep. 21 What Really Happens É. This is a comparison of the differences between DNA versus RNA, including … DNA AND RNA 4.2. Fully animated powerpoint of the structure of DNA and replication. The enzyme DNA primase combines a short fragment of RNA (primer) with the complementary constituents of the parent DNA. DNA needs to be copied when an organism reproduces and when a cell reproduces. Carries the genetic information Once the DNA has been replicated, there is one problem. Leading Strand. Unit 3. found in chromosomes, mitochondria and chloroplasts. 21.2 in Weaver 4 Replicon - DNA replicated from a single origin Eukaryotes have many replication origins. Unwinding of DNA The interaction of proteins with ori defines the start site of replication and provides a short region of ssDNA essential for initiation of synthesis of the nascent DNA strand. DNA 3. Hwk for 10/14: DNA Structure and Replication POGIL--Models 1 and 2 ONLY Introduction to RNA Gene expression: turning genes into specific traits, done by RNA. Process of DNA Replication B. Why is DNA replication “semi-conservative”? In the first step the single stranded parental RNA (+ strand), undergoes replication to form a double stranded parental replicating form (+—). Think of a medical transcriptionist copying the physicians words into another format. The RNA nucleotides are eventually replaced by DNA nucleotides when the DNA polymerase runs into them. DNA polymerase III. DNA is extended by adding a free nucleotide triphosphate to the 3′ end of the chain. The mechanism has been found to be similar to the replication of single stranded DNA. Be sure to include the following structures: Label 3’ and 5’ sides of DNA. DNA replication can occur only in one direction (but remember, these two strands are antiparallel). RNA polymerase binds to the promoter site (TATA box) (start) on the DNA 2. = <7./.3;G.D>;@> XH _ kWzd6OM.

And so you might remember that DNA is deoxyribonucleic acid, so the sugar backbone in RNA is a very similar molecule, well now it's got its oxy, it's not deoxyribonucleic acid, it's ribonucleic acid. 2 Viral Replication: Basic Concepts • Replication cycle produces-Functional RNA’s and proteins-Genomic RNA or DNA and structural proteins• 100’s-1,000’s new particles produced by each cycle-Referred to as burst size-Many are defective-End of ‘eclipse’ phase• Replication may be cytolytic or non-cytolytic Steps in Viral Replication: Attachment DNA, RNA, DNA Replication, Protein Synthesis and Mutations Review Game! -flow of information from DNA to RNA to protein-DNA uses itself as a template to make more DNA = replication-use DNA to make RNA = transcription RNA leave the nucleus and interacts with other structures to make proteins = translation 1.
