Which of the following events occurs in DNA replication in eukaryotes? Regulatory proteins bind to all of the nucleotides on the DNA molecule.

Enzymes “unzip” the DNA molecule by breaking the bonds between phosphate and sugar groups.

Replication starts from a single point and proceeds in two directions until the entire chromosome is copied.

Replication starts from multiple points and proceeds in two directions until the entire chromosome is copied.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
