WebMake a sketch of the double helix of DNA. Show how it unzips for replication and how complementary strands are built. Label the nitrogenous bases, replication fork, DNA polymerase, the original strand, and the new strand. Students' sketches should resemble the top part of the figure in the textbook. WebDNA polymerase III forms a phosphodiester bond to permanently incorporate the incoming DNA nucleotide into the new strand of DNA RNA primers Small segments of RNA that indicate to DNA polymerase where to begin replication, provide an available 3'-OH on the sugar, which can then be added to synthesizes new DNA only in the 5' to 3' direction

WebDec 18, 2015 · 4. Replication is the process of synthesis of daughter DNA from parental DNA by the enzyme DNA Polymerase. DNA replication is a biological process that occurs in all living organisms and copies their exact DNA. It is the basis for biological inheritance.

WebA cell containing a single chromosome is placed in a medium containing radioactive phosphate so that any new DNA strands formed by DNA replication will be radioactive. The cell replicates its DNA and divides. Then the daughter cells (still in the radioactive medium) replicate their DNA and divide, and a total of four cells are present. Sketch the DNA …
WebMar 1, 2024 · The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells. The S phase only begins when the cell has passed ...
WebExplain how the process of DNA replication depends on the structure of DNA. * 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. * helicase moves progressively down the molecules. * backbones are linked by covalent/ strong bonds. glook new townWebFeb 21, 2024 · The mechanism by which polymerase α - primase (polα-primase) synthesizes chimeric RNA-DNA primers of defined length and composition, necessary for replication fidelity and genome stability, is unknown.
