2.True or False: Transcription of DNA into mRNA does not require an

RNA primer.: true

3.Why must the DNA within eukaryotes be complexed with histone proteins, but not in bacteria? What happens to these complexes during DNA replica- 1 / 2

tion?: Because the amount of DNA in eukaryotes is greater in number

compared to bacteria. Due to the vast amount of DNA, it must be stored tightly. That is what the histone proteins allow. For the compaction/unravel of DNA in eukaryote cells.During DNA replication, the protein histone relaxes which allows the unwinding of the DNA. This is so DNA replication is able to take place.However, when it is over, the histone proteins go back to tightly holding DNA.
