A) the envelope of gases surrounding the Earth the envelope of gases surrounding the Earth
Explanation: A biosphere is layers of gas surrounding earth's atmosphere, the envelope of gases surrounding the Earth is the closest thing to that description.
Answer:
A. Helicases
B. Single strand binding proteins
C. Single strand binding protein
D. Topoisomerases
Explanation:
The helicases bind on the replication fork aiding in the unwounding of the DNA helix to allow for replication. The single strange binding proteins attach/bind to the separated single stranded DNA after the replication fork to prevent re-annealing of the single stranded DNA preventing Hydrogen bond formation that reanneals these two strands together. The topoisomerases are found just ahead of the replication fork preventing overwounding/ positive supercoils of the DNA. They do this by introducing breaks into the phosphate backbone of the DNA allowing them rotate forming negative supercoils and attaching the breaks once the DNA strand is relaxed.
Both the fantasin gene and the imaginin gene will be transcribed at high levels when activators specific for control elements A, B, C, D, and E are present in the cell.
Control elements C, D, and E are distal control elements for the imaginin gene.
