This image depicts a . In DNA, the pentose sugar's name is . There are different nitrogenous bases found in DNA. This macromolecule functions to store genetic information.
Below is a strand of DNA nucleotides:
ATCGGGCAAATT
Which of the following is the correct complementary strand of DNA nucleotides?
DNA Replication takes place in the of the cell. It begins when an enzyme called breaks hydrogen bonds in the center of the DNA, causing the DNA to untwist and unzip. Then, within the replication fork, a different enzyme called bonds new nucleotide strands to the parental template strands according to DNA's base pairing rule. Finally, an enzyme called checks the resulting DNA molecules for mistakes and re-twists them into their double helix shape.
Which TWO of the following statements best describes the result of DNA replicaton?
Even before DNA's structure and function were discovered, scientists predicted that there was a chemical molecule that was capable of storing genetic information. They also predicted that the molecule would be easily copied by cells. Why did they predict that the molecule that stored hereditary information would be easily copied by cells?
Which TWO of the following statements is TRUE about DNA?
Why is it necessary for a cell's DNA to replicate during interphase, prior to mitosis in the cell cycle?
