Suppose the following point mutation occurred in the DNA. Will this mutation affect the protein resulting from this gene sequence?

a. Yes, the 5th amino acid in the sequence has changed.

c. No, mutations in the DNA do not affect the mRNA sequence.

d. Yes, all mutations change the resulting protein.

The kind of fertilization found in the majority of aquatic animals is (internal or external) fertilization.

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.

Which of these is not a nucleotide base found in dna?
