Which of the following models describes the way in which DNA Replication occurs? dispersive conservative random semiconservative

In apoptosis, a process of programmed cell death, the cell undergoes controlled degradation of cellular components including nuclear DNA Researchers have noted that if the DNA is isolated from an apoptotic cell, it appears as distinct bands of multiples of approximately 145 bases in length. Why does this occur? Multiple Choice There is a specific DNase that digests DNA every 145 base pairs. DNA sequences that appear every 145 base pairs allows for easier DNA breakage. DNA that is wrapped around the histones is not being degraded. DNA is coated with transcription factors every 145 base pairs.

When comparing the three key models of DNA replication, the model that included the separation of the two strands of the original DNA (template) and using those strands as templates to synthesize two new DNA strands is called directional replication. dispersive replication. conservative replication. semiconservative replication.

What is the function of DNA primase in DNA replication? to insert new bases during elongation, using the parent strand as a template to anneal (splice) smaller fragments of DNA to create one continuous strand to create an RNA primer to initiate DNA replication to create replication bubbles by unravelling the parental strands of DNA all of the above

As DNA is replicated, both continuous and discontinuous replication occur. Discontinuous replication is the result of which specific feature of DNA? major groove antiparallel strands action of helicase at the replication fork purine and pyrimidine nucleotides covalent bonds

Help

The lagging strand of DNA is synthesized continuously in a 3' to 5' direction Discontinuously in a 5' to 3' direction Discontinuously in a 3' to 5' direction. In both 5' to 3' and 3' to 5'

Arrange the steps of DNA replication in the order that they occur. First step Helicase unwinds the DNA double helix. Last step Answer Bank DNA polymerase synthesizes DNA. RNA primers are added. DNA ligase joins DNA fragments together. RNA primers are removed. Single-stranded DNA-binding proteins bind to each template strand.

Describe how replication makes copies of DNA.  Include the following: helicase polymerase primase and primer ligase leading strand lagging strand base pairing rule (a-t, c-g) nucelotide  nucleus semiconservative
