There are differences between Eukaryotic and Prokaryotic cells. This difference is considered to be the most important distinction between groups of organisms.
A Prokaryotic cell does not contain a nucleus. It only contains one chromosome and is a single-celled organism. It was the only form of life on earth for millions of years. Examples of a Prokaryotic cell are the different types of bacteria present today.
A Eukaryotic cell contains a nucleus; more than one chromosome and is typically a multi-celled organism. <span>Both plant and animal cells are eukaryotic cells.

This is because it is the code language that tRNA uses during the process of translation.
In the cell, DNA has the genetic code for proteins needed for the cell to be able to function. To be able to make a particular protein, the code for that protein, which can be compared to a blue print has to be delivered from the DNA to the ribosome which can be compared to a work shop for it is here that amino acids, the building blocks of protein, are put together to form the protein.
In the cell nucleus, DNA transcribes (copies) the blue print on to mRNA, which then leaves the nucleus and carries the blue print to the ribosomes in the cell cytoplasm and attaches to a ribosome. tRNA begins to translate or read the information on the attached mRNA in triplets or codons and not as single nucleotides. Each codon is a code for a specific amino acid. tRNA then fetches amino acids (coded for by each codon) from the pool of free amino acids in the cytoplasm and brings them to the ribosome where they are joined to each other to form a chain thus creating the protein.
I believe you are looking for electromagnetic induction. Electromagnetic induction is the process by which a current can be induced to flow due to a changing magnetic field. I would take notes on this question you are having trouble with It would really help out if you did :)
This is evidenced by Doppler
shift effect. This is the phenomenon where waves that are coming from an object
that is accelerating towards your direction are heard at a higher frequency than that of
objects moving away from you. This is the same for light (which also has
wave-like properties). When observing distant galaxies, astronomers discovered that
they all showed to be redshift (change in the frequency of light towards red
color). This means that all galaxies are moving away from each other because
the universe is expanding.
