Why are Short Tandem Repeats (STR's) important to DNA fingerprinting?
2 points
O
STR's are found in RNA so they are easier to isolate and examine than DNA
STR's are the same for everyone so they serve as a "baseline" for comparison
the STR's repeat different numbers of time in different people, creating bands of
different lengths
the STR's in different people code for different proteins, which can be analyzed on a
gel

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
