Why do we need transcription?
DNA is transcribed into mRNA so the mRNA can travel out of the nucleus and bind to ribosomes to form proteins through translation. The DNA molecule cannot travel outside of the nucleus because it's too big to fit through the membrane surrounding the nucleus
Why is protein different in prokaryotes and eukaryotes?
In prokaryotes, DNA is stored in the cytoplasm. also prokaryotes have no nucleus In prokaryotes, transcription and translation happen at the same time.
What is making a real protein?
To make a protein, a cell goes through two processes, the first one is transcription and the second is translation. In the first stage, DNA helicase unwinds and unzips the two strands of a DNA double helix. Then DNA polymerase comes in and helps make a complementary strand called messenger RNA of mRNA. this mRNA is then cut up to the bare essentials, thus containing pretty much only the nucleotides coding for genes. Splicosomes are the molecules that do this cutting, known as splicing, which then makes the mRNA ready for action. The mRNA then travels outside of the nucleus, and finds a transfer RNA of tRNA molecule. The next step is translation, in which the actual building of the protein takes place. First off, the mRNA molecule is floating around, until it meets a ribosome. This ribosome is the site at which this mRNA will meet a tRNA molecule, containing a nucleotide sequence complementary to that of the mRNA. This tRNA has this nucleotide sequence at one end, and an amino acid on the other end. This amino acid is then put into the ribosome, into the A site of the ribosome. It then moves to the P site, where the polypeptide chain, or building of the protein is actually taking place. This amino acid is then adjoined to the chain, and is then part of the protein molecule. Once all of the necessary amino acids are joined in, the protein moves to the E site, where it exits the ribosome. This molecule is then complete, and will then proceed to the part of the cell where it is needed, and will start to function.

CH4 How much atom contained in each molecule?
One molecule has 5 atoms.One carbon and four hydrogens
What does percent composition tell you about a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What is the relationship between proteins and defects?
I don't have much time to answer this, but here's a quick answer. When a mutation occurs in the DNA or mRNA processing in an organism, it causes the protein to be transcribed in an abnormal form and will have an improper secondary and tertiary structure for the function it is supposed to serve. This results in a defect in the organism.
How much indidvidual atom are in one molecule of water?
The formula of water is H2O, showing that each molecule contains one oxygen atom and two hydrogen atoms. Therefore, each molecule contains three atoms.
How much chloride is in sodium chloride?
1 atom in each molecule (60,33417 %)
How much mass does a ch4 molecule have?
Add atomic masses of each atom.So answer is about 16
