Need someone to define these for me/ describe them: •dna helicase, replication forks(corigin the replication)

•dna polymerase, leading strand, lagging strand (Okazaki fragments)

• dna ligase links Okazaki fragment,2 semi conservative strands.

the backbone of the dna and rna compound is sugar phosphate.

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse

i need

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
