DNA stores a cell’s genetic information. During interphase, DNA replicates (makes a copy of itself). That's why during Prophase, there are already 2 copies of DNA (2 sister chromatids) connected together at the centromere. This is still considered one chromosome, but now it has twice as much genetic material. How does this help explain why daughter cells are identical after mitosis?

The phylogenetic tree illustrates the relationship between humans and our closest living relatives. the tree was based on biochemical comparisons, including dna and amino acid sequences. according to the biomolecular data, we could infer that a) the four organisms do not have a common ancestor. b) humans are more closely related to chimps than any other apes. c) chimps are more closely related to gorillas than they are to humans. eliminate d) there is no evidence if any relationship between the four branches on the tree.
