Can you please explain the question your trying to ask in more detail if you can please?
Explanation:
Epithelial tissue covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection, secretion, absorption, and filtration.
<u>Explanation:</u>
- Epithelial tissue spreads throughout the body surface covering line body cavities and hollow organs which form the major tissue in the glands. Epithelial tissue covers the outside of the body and lines organs, vessels, and cavities.
- Endothelium joins with the inner tissue lining which covers the brain, lungs, skin, and the heart. It acts as a barrier protecting the body and the environment and maintains the process of protection, filtration, absorption, excretion, and sensation.
- Covering and lining epithelium and the Glandular epithelium which helps in surrounding the glands within the body surface are the characteristics feature in the human body.
In the beginning <span>of the RNA strand as a cap, a modified guanine nucleotide is added. After this, there is a removal of those segments of the RNA strand that do not actually code for the protein. And those RNA’s segments that do code for the protein are reconnected. And forking a tail, extra adenine nucleotides are added to the end of the RNA strand. The mRNA or messenger RNA which is already completed will then leave the nucleus. This whole process is called the RNA processing. Before the RNA copy of a protein encoding can be transported out of the nucleus and translated into protein, it must be first be modified in several ways. A precursor of mRNA, pre-mRNA is the primary transcription product of a gene. </span>
Answer:
it is accepted that cells contain DNA in chromosomes and RNA in the nucleus and cytoplasm, but only in the modern cell theory. the classical cell theory does not include this. but using either classical or modern theory, it is false that all cells have DNA surrounded by a nucleus.
Explanation:
Hope this helps.
