- AKS 5b: Which statement is correct regarding the semiconservative nature of DNA? * The semiconservative nature of DNA allows for genetic stability in somatic gene production MRNA operates as a template to allow DNA to replicate itself using ribosomes The structure of the phosphate group on the DNA molecule direct the correct nucleotides into place during replication Nucleotides in each original strand serve as a template for the new strand to be made AKS 5b: Which model accurately represents the semi-conservative nature of DNA replication? * * AA AA AA AA АВ ВА AA BB AA AA АВ АС Figure A Figure B Figure C Figure Darrow_forwardLook at the picture carefully below and imagine inside a cell nucleus. a) encircle and name the parts where DNA is most accessible and least accessible b) how nucleosome positioning or spacing can interfere with DNA accessiblityarrow_forwardHi there ~ I was wondering if someone could help me with DNA and RNA. I'm having a LOT of difficulty grasping it. I know the below are THREE questions, however I thought for the sake of explaining purposes, it may make more sense to put them all together.

- The diagram depicts one strand of DNA at the end of a chromosome. This strand has been replicated and produced two fragments, as shown below. Which of the two gaps that exist, labeled (a) and (b), can be filled by DNA polymerase? Hint: remember the directionality requirement for DNA polymerase. a) gap (a) b) gap (b) c) both gaps (a) and (b) d) neither gaps (a) nor (b)arrow_forwardCan you help me with this question?arrow_forwardWhich of the following statements are true regarding the properties of DNA and RNA polymerase. Select all that apply. Both DNA and RNA polymerase synthesize nucleic acid strands in the 5" to 3' direction. Both DNA and RNA polymerase can initiate strand synthesis on their own. I. RNA polymerase initiates strand synthesis, while DNA polymerase depends upon an existing strand to continue synthesis. II. RNA polymerase only uses ribonucleotides for strand synthesis. DNA polymerase only uses deoxyribonucleotides for strand synthesis. V. Au DNA and RNA polymerases from eukaryotes behave very differently from DNA and RNA polymerases found in prokaryotes.

See Figures 8.12 and 8.13. FIGURE 8.12 In DNA replication, the two polynucleotide strands uncoil, and each is a template for synthesizing a new strand. A replicated DNA molecule contains one new strand and one old strand. This mechanism is called semiconservative replication. FIGURE 8.13 A close-up look at the process of DNA replication. (a) As the strands uncoil, bases are added to the newly synthesized strand by complementary base pairing with bases in the template strand. The new bases are linked together by DNA polymerase. (b) DNA synthesis can proceed only in the 5 3 direction; newly synthesized DNA on one template strand is made in short segments and linked together by the enzyme DNA ligase.arrow_forward

In order to examine the sample, he increased its quantity by cycling the sample through the polymerase chain reaction. He estimated that there were 50,000 copies of the DNA in his original sample. Derive a simple formula and calculate the number of copies he will have after15 cycles of the PCR.arrow_forwardFigure 14.14 You isolate a cell strain in which the joining of Okazaki fragments is impaired and suspect that a mutation has occurred in an enzyme found at the replication fork.
