Answer:
The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer.
Explanation:
Answer:DNA is antiparallel.
Explanation: DNA is a double stranded helix in which the two strands are antiparallel. Being antiparallel means that as one strand runs from 5'->3' direction, the other strand runs from 3'->5' direction. During DNA each of the two strands serves as a template for a new complementary strand. The synthesis of a new DNA strand is always in the 5'->3' direction, therefore one strand is synthesized continuously in the direction of the replication fork while the other strand is synthesized discontinuously in the direction opposite to the replication fork in short fragments called the Okazaki fragments. The strand that is synthesized continuously is called the leading strand while the strand that is synthesized discontinuously in Okazaki fragments is called the lagging strand.

Answer: Comparing the DNA sequence of the organisms can also tell you how closely related species they are. It can give you even more information since the original DNA is how the amino acid sequence of cytochromes is coded for.
Looking at embryonic development also helps you determine the phylogeny of organisms because a way an embryo develops can be very similar to the way another species develops but then both are full-grown they look very different and its tuff to explain how close they might be related
