X2 田田用困 Í {} +] 図Evolution accounts for the unity and diversity of life, and the continuity of life is based on heritable information in the form of DNA. In a short essay (100-150 words), discuss how the fidelity with which DNA is inherited is related to the processes of evolution. (Review the discussion of proofreading and DNA repair in Concept 16.2.)In relation to central dogma of molecular biology answer the following questions: A- Give two reasons why the DNA replication is asymmetrical process (i.e. the DNA replication outcome is different between the leading and lagging strands)? B-The following segment of DNA is part of the transcription unit of a gene. You know already that RNA polymerase moves in a specific direction along this piece of DNA to convert one of the DNA strands into a single strand RNA transcript so that this entire region of DNA is made into RNA. 5′-GGCATGGCAATATTGTAGTA-3′ 3′-CCGTACCGTTATAACATCAT-5′ Given this information, a student claims that the RNA produced from this DNA is: 3′-GGCATGGCAATATTGTAGTA-5′ Give two reasons why this answer is incorrect. C- Imagine that the mRNA codons consisted of only two nucleotides instead of three nucleotides. Would there be a sufficient number of codons for all twenty amino acids? Explain your answer. D- The length of a particular gene in human DNA,…
- DNA is responsible for your phenotype, but to what extent? How much, if at all, do environmental factors play a role? Can you find examples (remember keep your sources academic)?All the following statements about DNA are true, EXCEPT: O DNA is a double-helix, consisting of a sugar-phosphate backbone. O DNA is made up on nucleotides, which consist of one sugar, one phosphate, and one base. O DNA consists of 4 bases - adenine, uracil, cytosine, and guanine. The two main functions of DNA are to replicate itself and to create proteins (by providing the template for protein synthesis). O The sugar in DNA is deoxyribose.Sarah is a scientist looking at specific sequences of base pairs on a DNA molecule within a specific cell. Which of the following pairings would she most likely observe in this DNA molecule? O Equivalent A and C base pairs O When she adds G and C base pairs together that would most likely equal the addition of A and T base pairs together O When she adds A and C base pairs together that would most likely equal the addition of G and T base pairs together O EquivalentA and G base pairs while C and Tsc pairs are equivalent
- One of the following is a characteristic of eukaryotic genetic material? 1. Eukaryotic genetic material is compacted by wrapping the double-helix around histone proteins to form nucleosomes. 2. Eukaryotic genetic material consists of supercoiled circular DNA molecules complexed with proteins into chromosomes. 3. Eukaryotic genetic material consists of relaxed linear DNA molecules complexed with RNA into a 30 nm fiber. 4. Eukaryotic genetic material is compacted by folding linker regions around non-histone proteins to form a scaffold.DNA is known to be the repository of genetic information in each living cell, which its integrity and stability are essential to maintain life. Its trait of not being inert is subjected to assault from the environment, and any resulting damage. if not repaired, will lead to mutation and possible disease. Solve of the following DNA damage problem in the patient below with suitable repair mechanism. Patient with disease xeroderma pigmentosumThe "Central Dogma of Life" states that the pattern of information that occurs most frequently in our cells is: O From existing proteins to make new RNA. From new RNA to make DNA. From existing DNA to make new DNA. O From existing DNA to make new DNA. From DNA to make new RNA. From RNA to make new proteins. From existing RNA to make new DNA. From DNA to make new proteins. From existing proteins to make new proteins. All of these occur at different stages of organisms' lives.
- DNA is a universal code used by all organisms. Which of the following is an incorrect statement about DNA? * O DNA strands always run antiparallel to each other. O When DNA is condensed around proteins, it is considered chromatin. O A karyotype shows the quaternary structure of chromosomes. O A genome includes all of the genes of an organism.Which of the following sequences is the best description of the complementary DNA sequence to the following sequence: 5'-CGATTAGC-3' Group of answer choices 5'-GCTAATCG-3' 5'-GCUAAUCG-3' 3'-CGATTAGC-5' 3'-GCUAAUCG-5' 3'-GCTAATCG-5'All EXCEPT which of the following statements are evidence that DNA, and not protein, is the genetic material in eukaryotes as well as bacteria? Group of answer choices DNA is located in the cell where the primary genetic function is known to occur. Introduction of a human DNA coding for insulin into bacteria results in bacterial cells that can produce human insulin All of these are evidence that DNA is the hereditary material in eukaryotes. Mice that are transgenic for DNA coding for rat growth hormone grow to be twice normal mouse size. UV light is most mutagenic at a wavelength at which DNA and RNA strongly absorb.
