Hi im alevels too. From what I understand, DNA in prokaryotes doesnt close around histones in prokaryotes. I won't call it chromosome but maybe just circular DNA ?

can you call both "plasmid DNA" and "chromosomal DNA" as "chromosomes"?

Can you rephrase your question, it doesn’t make much sense.

oh I thought they were just chromosomes but in a circular shape instead of thread-like ones.
thanks tho!

Yes, bacteria have a single chromosome in addition to plasmids. Both the chromosome and plasmids are circular.

sorry just to clarify. So, both "plasmid DNA" and "chromosomal DNA" are chromosomes. Each bacteria possesses a single chromosome ("chromosomal DNA") or additional chromosomes ("plasmid DNA")?

Are you taking edexcel? Then bacteria don't have chromosomes ; they have circular DNA.

No, plasmids are not considered chromosomes. They contain fewer genes than the chromosome and are often passed between different bacteria.

can u also help me with this one plz?
when the translocation happens in plant phloem, does it transport food molecules (e.g. sucrose) in a form of cell sap (which is sucrose with water)?

do chromosomes (including chromosomal DNA found in bacteria) have proteins called histones?
