Explain why each chromosome must become two strands before the cell divides.

To allow transcription enzymes to access the DNA strand

Explanation:

The DNA double helix is made up of two complementary strands wound around each other, and tightly packaged as chromosomes.

DNA and RNA polymerases promote either DNA or RNA synthesis by attaching free nucleases to parent strands (a), which are then unwound and isolated by helicases (b). DNApolys synthesize DNA in a 5'-3 ' direction; owing to its restricted flow, there are only two types of replication: continuous from the point of differentiation of chromosomes, fork, and discontinuous from the fork.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.
