What else can I help you with?
Can the nuleus and the nucleolus be seen during interphase?
yes they are both present in interphase
Is a nucleolus a animal or plant cell?
Nucleolus is in nucleus.Nucleus can be seen in eukariyotes.
What is the small dot-like structure inside the nucleus?
The small dot-like structure inside the nucleus is the nucleolus. It is responsible for producing ribosomes, which are essential for protein synthesis. The nucleolus is not surrounded by a membrane and can often be seen as a distinct structure within the nucleus.
Is the nucleolus found in a plant cell and a animal cell?
It is in both cells. It is in the nucleus.
Can chromosomes be seen only during cell division?
No, chromosomes can also be seen in non-dividing cells during interphase under a microscope. In interphase, chromosomes are less condensed and appear as long, thin, thread-like structures within the nucleus. During cell division, chromosomes condense further to become more visible as distinct structures.
Cells nucleus during interphase?
DNA is always present in every stage of the cell cycle...reproducing it is the whole purpose of the cell cycle! In interphase, there are three phases: the cell grows (G1), duplicates each strand of DNA (S), and gets ready for mitosis (M). During the first part of interphase the chromosomes are long and thin, and single-stranded, making them very hard to see without a very powerful microscope. During the last 2 stages of interphase, the DNA is duplicated but is still long and thin. It is only in the prophase stage of mitosis that they are condensed enough to often be seen with a "normal" microscope on high power (400x) . By the end of mitosis, the doubled-chromosomes have been pulled apart and into opposite ends of the parent cell. When the cell has finished dividing, each "daughter cell" has the original number of single-stranded chromosomes. The chromosomes "uncoil", and the cell matures during G1 phase of interphase. Many people believe that DNA and/or Chromosomes (Chromosomes are made of DNA, remember.) are only present during mitosis. They just get fatter during mitosis by coiling tighter. Thus they are more easily seen. BUT.. just because you don't see them in interphase doesn't mean they aren't there!
What are some of the characteristics of the nucleolus?
The nucleolus is a prominent structure in the nucleus, primarily responsible for ribosome biogenesis. It is composed of proteins and RNA, and is involved in processing and assembling ribosomal subunits. The nucleolus is not membrane-bound and can be seen under a microscope as a dense region.
Why are individual chromosomes more difficult to see during inter phase than during mitosis?
The individual chromosomes cannot be seen in interphase because they haven't been condensed yet. That's what happens during mitosis so that it is easier to seperate them into new daughter cells. While in interphase, its called chromatin.
The dark spot seen in the nucleus in non dividing cells where RNA for ribosomes is made is called the?
The dark spot seen in the nucleus in non-dividing cells where RNA for ribosomes is made is called the nucleolus. It is responsible for producing ribosomal RNA and assembling ribosomal subunits, which are essential for protein synthesis within the cell.
What is a ball of DNA that can be seen in the later stages of interphase?
Centrioles
What structure do you see in a nuclei?
In a eukaryotic cell, the nucleus contains genetic material (DNA) organized into chromosomes. The nucleus is surrounded by a nuclear envelope, which consists of a double membrane that regulates the passage of molecules in and out of the nucleus through nuclear pores. Additionally, the nucleus contains a nucleolus, where ribosomal RNA is synthesized and ribosomes are assembled.
What stage does the cell spend most if its time in the cell cycle?
Interphase, which is the first stage in the cell cycle
