Twisted Ladders
These form the rails of the DNA ladder.
What are the phosphate-sugar backbones?
These two scientists discovered the structure of DNA.
The cell cycle of a typical body cell consists of Interphase, Mitosis, and this.
The G in G2 stands for this.
This enzyme is responsible for reading and copying DNA.
This type of bond connects the two strands of a DNA double helix.
Segments of DNA copied from the lagging strand that need to be joined together.
The longest part of interphase is this.
DNA replication occurs in this part of interphase.
This enzyme opens up the DNA double helix in preparation for replication.
This structure was Linus Pauling's model of DNA.
The name of the scientist who took X-ray crystallography images of DNA with Rosalind Frankin and Maurice Wilkins.
In this stage of mitosis the two sets of chromosomes have reached opposite poles.
The part of mitosis that occurs right before metaphase.
This enzyme joins together sections of DNA.
These are proteins around which DNA loops twice.
They worked with bacteriophage to determine that DNA, not protein, was the hereditary material.
These are pauses in the cell cycle to ensure proper completion of a step.
Cells that have no growth or activity are said to be in a stage of permanent rest called this.
Avery, MacLeod, and McCarty used this enzyme to destroy DNA.
The number of hydrogen bonds in this sequence and its complement, plus the number of base pairs: G-G-T-C-A-C
Griffith transformed non-virulent R cells with DNA from virulent S cells. This is what R and S stand for.
This indentation in the plasma membrane forms as an animal cell pinches inward during cytokinesis.
This is the number of chromosomes found in each daughter cell when a human liver cell divides.
This enzyme is responsible for proofreading DNA replication.
