2describe the process of dna replication during dna replication, the dna makes copies of itself this happens during the s phase of cell cycle the replication starts in specific parts of dna called “origins of replication” dna helicase- is an enzyme that opens or unzips the double helix so there are two strands ready to be replicated. Chapter 10 essay questions 1 define genetic engineering and biotechnology 2 a) describe the processes involved in denaturing and renaturing of dna b) what is useful about this procedure c) why is it necessary to denature the dna in the southern blot test d) how would the southern blot be used with pcr 3. An essay or paper on the process of dna replication dna is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail it is composed of four ring shaped organic bases (nucleotides) which are adenine (a), guanine (g), cytosine (c) and thymine (t.
4 how does dna replication ensure accuracy when dna is replicated, you wind up with 2 dna molecules however, one strand of each of the new dna molecules is the original dna, and one strand is newly synthesized the proof reader enzymes check the new copy against the original strand to make sure the bonding rules are followed 5. Previous ib exam essay questions: unit 4 use these model essay question responses to prepare for essay questions on your in class tests, as well as the ib examination, paper 2 these questions have appeared on recent ib examinations, exactly as shown below. Essay # 1 meaning of dna: a nucleic acid that carries the genetic information in the cell and is capable of self-replication and rna synthesis is referred to as dna.
Previous ib exam essay questions: unit 4 explain how the process of dna replication depends on the structure of dna 9 marks dna molecule is double (stranded) hydrogen bonds linking the two strands are weak/ can be broken dna can split into two strands split by helicase. Study the following questions to prepare for your exam the answers provided by your classmates in class can be viewed by clicking on the answer link 1) living organisms use dna as their genetic material. Dna replication to understand the process of dna replication, you much first be familiar with the structure of dna resembling a twisted ladder, dna is a double helix formed with nucleotides, a phosphate and sugar backbone, and nitrogenous bases.
On paper, replicate the following segment of dna: 5’ atcggctacgttcac 3’ 3’ tagccgatgcaagtg 5’ a) show the direction of replication of the new strands and explain what the lagging and leading strands are b) explain how this is semiconservative replication. Short essay questions explain how and where dna replication occurs and how this fits into the cell cycle and the process of mitosis include the following processes in your explanation.
Essay # definition of dna replication: dna replicates by “unzipping” along the two strands, breaking the hydrogen bonds which link the pairs of nucleotides each half then serves as a template for nucleotides available in the cells which are joined together by dna polymerase. Questions and answers related to dna replication and polypeptides essay however if it was not folded into a certain shape, it would not become a protein, rather just a polypeptide although ultimately both polypeptides and proteins are chains of amino acids, in order to form a protein the amino acids have to be in a specific order, contrasting.
In this essay, we will observe how dna replicates itself, the process making proteins, and gene regulation dna must duplicate itself in order to form complete copies of the genetic material dna replication is a complex task.
