During agarose gel electrophoresis of dna, shorter dna molecules typically migrate faster than longer molecules. when closed-circular dna molecules of the same size possess different linking numbers, these dna molecules will also separate during agarose gel electrophoresis. a sample of purified plasmid dna of uniform length was separated on an agarose gel and stained, as shown below. in addition to a strongly stained band (b), the gel shows a faintly stained band (a) that migrated a much shorter distance. select the statement that explains why two bands appeared in the migration pattern.

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.

In what part of a chloroplast does glucose production occur? a. atp synthase b. photosystem ii c. photosystem d. stroma
