Which tells you more about a protein its amino acid sequences or composition?

i'd go with the amino acid sequences... they are, after all, the second genetic code, meaning they are the blueprint for the function of the amino acid.


What tells a ribosome how to a protein?

DNA tells a ribosome how to assemble a protein.


What tells ribosomes how to assemble a protein?

DNA tells a ribosome how to assemble a protein.


What does A triplet codon specify?

It tells what amino acid to be created.


What is the first amino acids in most proteins?

Methionine. It functions as the "start" codon (tells the translation apparatus to start translating) and as a result is usually the first amino acid. However, it is frequently removed later. Methionine is by far the most common amino acid to find at the beginning of a chain, and will almost always have been there at some stage during protein synthesis. There is no other amino acid you can confidently claim is the first amino acid in anything but a small proportion of proteins.


What three letter code tells that the protein ia complete?

The three letter code that indicates which amino acid comes next in a protein is called a codon. These codons are on the mRNA transcript that is read by ribosomes to translate into protein.


Why do you have stop codons that signal the end of the amino acid chain?

A stop codon signals a termination of translation - in other words that the protein being built from the amino acid instructions is complete. They bind "release" factors that allow the completed protein to come away from the template.


What does the tertiary structure of a protein tell you about the protein?

It tells us about the three dimensional structure of the protein in its folded configuration.


What tells the male protein to destroy the female pheromone?

Coded messages from the DNA in the protein


When a tRNA anticodon binds to an mRNA codon does the amino acid detach from the tRNA molecule and bond to the end of a growing protein chain?

yes very much so, it's the anti-codon that tells the tRNA which amino acid to go get


Formed of an mRNA base triplet?

An enzyme Rna polymerase but I am not totally sure I am researching genetics just as a layman tRNA (transfer RNA) is responsible for picking up amino acids from inside the cytoplasm and "transfering" them to the site of translation in the ribosome mRNA (messenger RNA) tells the ribosome what order to put the amino acids in to make a particular protein


What is protein localization?

Protein localization is the process of figuring out where in a cell a particular protein is located. If you want some insight into the function of a protein its always a good idea to know where it is in your cell and when i.e. the protein's location. Most proteins have N-terminal sequences that, in one way or another, tells the cell where to send the proteins its just made. For example, the protein may be directed towards the cell membrane ready for secretion. A common protein localization technique is to fuse a protein with a florescent amino acid sequence which the protein then drags about with it giving away its location to a florescent sensitive microscope. This can even be done in real time.
