A problem known as the end-replication problem (telomere problem) exists in eukaryotic chromosomes wherein the chromosomes shorten with each round of DNA replication. Select the statements that best explain why the end-replication problem exists in eukaryotic chromosomes (select all statements that apply)
1) The RNA primer is removed in a 3' to 5' direction
2) DNA polymerase requires a primer for DNA synthesis
3) DNA ligase links the 5' OH group of one fragment to the 3' phosphate group of an adjacent fragment
4) The lagging strand is synthesized from the 3' end to the 5' end
5) DNA polymerase synthesizes DNA from the phosphate end to the hydroxyl end

Solar energy causes water to evaporate into the atmosphere. how does that water vapor become a cloud? a) as the water vapor goes higher in the sky, the air gets cooler. the cooler air causes the water vapor to condense. b) as the water vapor goes higher in the sky, solar energy causes it to condense around particles of dust. c) as the water vapor goes higher in the sky, the air gets warmer and the water vapor begins to condense. d) as the water vapor goes high into the atmosphere it turns to ice and that's what forms clouds.
