SOLVED: 2. The double-helix model of DNAThe double-helix model of DNA is shown here. One strand pointsupward in the 5’ to 3’ direction. In the image, label whichdirection the other arrow points. A Hydrogen bonds between bases on opposite strands hold this DNAhelix together. How many hydrogen bonds form between a singleguanine (G) and its complementary base? Examine the distance between base pairs and the length of onefull twist of the double helix. How many base pairs long is onefull twist o

The Double Helix

DNA Replication

SOLVED: As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two component strands. This unwinding and separating of the DNA requires three different types of proteins: helicase, topoisomerase, and single-strand binding proteins. Sort the phrases into the appropriate bins depending on which protein they describe.a. Bind at replication forkb. Bind after replication forkc. Prevent H-bond between basesd. Break covalent bond in
