A cell undergoes a nuclear division and separation of the cytoplasm, after which the number of cellular organelles is doubled, and cell size increases greatly. However, a malfunctioning enzyme (helicase) prevents separation of the DNA strands.
What is the consequence of this malfunction?
Anaphase during the G1 phase cannot occur.
Anaphase during the Sphase cannot occur.
DNA replication during the G1 phase cannot occur.
DNA replication during the Sphase cannot occur.

DNA replication during the Sphase cannot occur.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
