Does helicase enzymes break the sugar phosphate backbone?

No, helicase enzymes unwind and separate the double-stranded DNA helix by breaking the hydrogen bonds between complementary nucleotide base pairs. They do not break the sugar-phosphate backbone of the DNA molecule.


What effect does detergent have on surface tension and Why?

There is an effect on Surface Tension when detergent is put in the water. I am doing an experiment for my upcoming Science fair and i am doing a Detergent Powered Boat/Surface Tension...I have tested it many times with and without detergent, when it doesn't have detergent it floats and then sinks after 5 seconds but with detergent it zips through the water...I can not give you the reason for this as i am myself still researching on why this is!


How does a chromosome become 2 strands?

During DNA replication, a chromosome becomes two strands through a process called semi-conservative replication. The double helix structure of the DNA molecule unwinds with the help of enzymes, such as helicase, creating two separate strands. Each original strand serves as a template for the synthesis of a complementary new strand, resulting in two identical DNA molecules, each with one original strand and one newly synthesized strand.
