The RNA nucleotides are eventually replaced by DNA nucleotides when the DNA polymerase runs into them. RNA Transcription: process of creating RNA from DNA 3. Detailed tutorial of DNA from basic units- sugars, phosphates and bases- then how nucleotides link to form chains, the double helix. Structure Of DNA & RNA By Himanshu Dev VMMC & SJH 2. Be sure to include the following structures: Label 3’ and 5’ sides of DNA. RNA … Usually DNA is double stranded structure (single stranded DNA also occurs). RNA = ribonucleic acid. 2 DNA DNA is a polymer made of monomers called nucleotides . It is … 2. has uracil instead of thymine 3. has ribose instead of deoxyribose. 20.12 in Weaver Another way to see that DNA replication is Bi-directional -- Cleave replicating SV40 viral DNA with a restriction enzyme that cuts it once. From the Virtual Cell Biology Classroom on ScienceProfOnline.com Transcription Process by which a DNA sequence is copied to produce a complementary RNA. mRNA has the job of taking the message from the DNA to the nucleus to the ribosomes. Title: DNA Replication Author: Robert and Marsha Goodman Last modified by: Bow School District Created Date: 4/13/2010 2:54:35 PM Document presentation format – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 56612b-YmEyM DNA nucleotides have three parts: Sugar called “deoxyribose” Phosphate group Nitrogenous base 3 DNA replication can occur only in one direction (but remember, these two strands are antiparallel). DNA polymerase I. RNA primase. 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 Origin of Rep. 19 Replication Fork Origin of Rep. 21 What Really Happens É. ��ࡱ� > �� � � ���� � � � � � � � � � � � � � � �������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������� n�O l�/e).�b��ƚ���PNG DNA Deoxyribonucleic acid DNA - a polymer of deoxyribonucleotides. 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. Why is DNA replication “semi-conservative”? 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. Carries the genetic information 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. DNA Helicase allows for processive unwinding of DNA. DNA REPLICATION Figure 4.2: DNA replication. Introduction to RNA Gene expression: turning genes into specific traits, done by RNA. Usually RNA is single … DNA structure beginning with the basics. This is a comparison of the differences between DNA versus RNA, including … DNA Replication, Transcription, and Translation - DNA Replication, Transcription, and Translation DNA versus RNA Double Stranded Single Stranded Adenine-Thymine Adenine-URACIL Cytosine-Guanine Cytosine ... | PowerPoint PPT presentation | free to view The enzyme DNA primase combines a short fragment of RNA (primer) with the complementary constituents of the parent DNA. DNA polymerase III. In the first step the single stranded parental RNA (+ strand), undergoes replication to form a double stranded parental replicating form (+—). -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. Two new DNA molecules are created- each have one parent strand and one new strand- … Fully Editable Teacher Edition. were to be copied sequentially by 10,000 secretaries, one copying the output of another, the results would contain quite a lot of gibberish by the time the task was completed. The DNA Processes Power Point covers DNA replication and protein synthesis: DNA transcription and translation. Students will be able to explain the difference between DNA replication an 1st step: copy part of the DNA sequence into RNA (Ribonucleic Acid). Topoisomerase. Genetics - DNA Overview: word Answers Ch. DNA is extended by adding a free nucleotide triphosphate to the 3′ end of the chain. DNA Replication DNA must be copied. The usual replication machinery provides no way to complete the 5 ends, so repeated rounds of replication produce shorter DNA molecules. Chapter 8 Lecture Outline See PowerPoint Image Slides for all figures and tables pre-inserted into PowerPoint without A summary of each process follows the full length explanations. 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. The mechanism has been found to be similar to the replication of single stranded DNA. DNA AND RNA 4.2. Think of a medical transcriptionist copying the physicians words into another format. In other words, it is the transfer of genetic information from DNA into RNA.

DNA-replication-revised.ppt - DNA Replication Summary Enzymes and proteins involved Process of replication in eukaryotes and prokaryotes Other functions. Helicase. 21.2 in Weaver 4 Replicon - DNA replicated from a single origin Eukaryotes have many replication origins. DNA replication begins at specific sites called origins of replication. Fig. DNA Replication: process of creating a new DNA molecule 2. Pol III structure --> Model for DNA complex DNA replication is semi-conservative. Origin of replication The consensus sequence of oriC With a whiteboard marker, draw and make labels to show how DNA replication occurs. oriC: origin of replication in E. coli: OriC 245 bp (3 13-nt and dnaA binding sites) in 4.8 m bp genome. found in chromosomes, mitochondria and chloroplasts. Single-stranded DNA-binding proteins (SSBs) stabilize this complex. DNA polymerase enzymes are specialized for different functions. DNA Mutation Notes and Ppt. Fully animated powerpoint of the structure of DNA and replication. This strand of mRNA is EDITED before leaving the nucleus & carrying the code into the cytoplasm NEW edition is interactive. Once the DNA has been replicated, there is one problem.

Lagging Strand. Another enzyme called DNA Primase codes for a small RNA primer, which facilitates the activity of DNA polymerase. RNA polymerase binds to the promoter site (TATA box) (start) on the DNA 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. 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. Usually double stranded.

Structure of DNA: DNA is a polymer of deoxyribonucleotides (or simply deoxynucleotides). DNA polymerase, which is the major replication enzyme, needs a primer at which it can add the first nucleotide.
