One of their primary distinguishing characteristics is the lack of a nuclear membrane and other vital cell organelles in prokaryotic cells.
What distinguishes prokaryotes from other organisms?Organelles are absent from prokaryotic cells, they lack a nucleus, and they are much smaller than eukaryotic cells. Every prokaryotic cell is protected by a cell wall. Many also contain a slime layer or capsule made of polysaccharides. Protrusions (appendages) are a common feature of prokaryotes.
What component of a prokaryotic organism is the most crucial?A prokaryotic cell places a lot of importance on its cell wall. It aids in a variety of ways, including preserving the cell's shape, offering safety, and keeping the cell from exploding.

How does RNA polymerase determine which strand is the template/antisense strand?
Answer:
Although RNA polymerase must recognize sequences on the template strand, by convention we draw the DNA sequence and regulatory signals on the "mRNA-like" strand. (This makes it simpler to directly determine the sequence of the resulting RNA.) The upper strand of DNA is the "mRNA-like" strand.

What is the relationship between a chromosome and DNA?
Chromosomes manufacture DNA.
Chromosomes are made of DNA.
DNA is made of chromosomes.
DNA manufactures chromosomes.
Answer:
(B) Chromosomes are made of DNA.
Explanation:
i took the test <3
Chromosomes are made of DNA which shows the relationship between a chromosome and DNA. So, the correct option is B.
What are Chromosomes?A chromosome is indeed a lengthy DNA molecule that contains all or a portion of an organism's genetic code. The very long, thin DNA fibres in most chromosomes are covered with packing proteins; in eukaryotic cells, the histones are the most significant of these proteins.
Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule. Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure. The fact that DNA is a component of chromosomes demonstrates the connection between chromosomes and DNA.
Therefore, the correct option is B.

Can someone please help me answer this question? Thank you.
Answer:
The correct answer is -
C is parent cell
A is under meiosis
B is a sex cell
Explanation:
In the given question, the diagram shows three different cells in which the cell C is the parent cell that is about to undergo meiosis that can be identified by the quantity or numbers of chromosomes present in the cell which is highest among all.
The cell that is already in the meiosis is cell A, it is the cell that is produced after meiosis 1 in the meiosis cell division as it has half number of chromosomes to parent cells.
The sex cell or gamete is cell C that has a haploid number of chromosomes which makes this process reduction division
