Answer:

The levels of organization range from a single organelle all the way up to a highly structured hierarchy.cell governs all physical and chemical process in life.
Answer:
b. orientation dependent
e. located upstream of the gene it controls
Explanation:
Promoter sequences:
These are the sequences present within the DNA on which RNA polymerase binds and start transcription of a gene. These sequences are present directly upstream of transcription initiation site at the 5' end.
Prokaryotes and Eukaryotes both have specific promoter location site which is fixed. So first (a) and Last (f) options of this question are wrong.
This sequence have specific orientation Like TATA box so these are orientation dependent.
These sequences are present directly upstream of transcription initiation site at the 5' end.
Answer:
Eukaryotes grow and reproduce through a process called mitosis. ... Most prokaryotes reproduce asexually and some through a process called binary fission. During binary fission, the single DNA molecule replicates and the original cell is divided into two identical daughter cells.
