Transcription in bacteria differs from transcription in a eukaryotic cell because __________________________. (a) RNA polymerase
Serggg [28]

The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.

More differences between prokaryotic and eukaryotic transcription:

• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,

• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).

• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.

• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.

Explain the difference between chromosomes, chromatids and chromatin. (3-4 sentences)
Drupady [299]

In eukaryotes, DNA is found in chromosomes in the nucleus. Chromosomes are made of a single molecule of DNA and proteins. Chromosomes are linear, and DNA in them is double stranded. There are many chromosomes in a single nucleus. In prokaryotes, a single DNA molecule which is double stranded forms the chromosome. There are no proteins in the chromosome. In viruses, the genetic material is either DNA or RNA. They may be double stranded or single stranded. It may be circular or linear.
