During dna replication in e. coli, what is the role of dnaa? a. dnaa prevents reannealing of the separated dna strands so replication can occur. b. dnaa binds to and bends dna, hydrolyzing hydrogen bonds in the 13-mer region of oric and creating an open complex c. dnaa is a helicase that uses atp to hydrolyze hydrogen bonds and separate dna strands d. dnaa carries the helicase protein to the open region of dna where hydrolysis and strand separation will occur e. dnaa is a region of dna recognized by the replisome where replication is initiated

What is a limitation of using a chemical formula, such as c6h1206, to represent a compound? the chemical formula does not show the types of elements that make up the compound. the chemical formula does not show how the atoms are connected to one another the chemical formula does not show the number of atoms of each element in a molecule. the chemical formula does not show the chemical symbols of the elements in the compound

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.
