A certain protein is made up of 100 amino acids What is the smallest number of bases in the messenger RNA molecule that is needed to carry the code for the synthesis of this protein?

for mRNA, it takes 3 bases (A codon) to signal that a specific amino acid should be used. In this case you would need 100x3 = 300 bases.

Does DNA directly controls protein synthesis?
When protein synthesis must take place, the code to make the protein is on the DNA in the nucleus but the protein is made at a ribosomal site in the cytoplasm. The code is copied from the DNA by a special molecule called messenger RNA (mRNA) which leaves the nucleus through a pore to go to the ribosome.
An error in genetic information present in a body cell of a mammal would most likely produce?
a mutation that will affect the synthesis of a certain protein in the cell
How does a ribosome produce protein in a Cell?
Ribosomes start protein synthesis in the cytoplasm. Synthesis is completed either in the cytoplasm or in the lumen of the rough endoplasmic reticulum.All proteins begin as polypeptides (chains of amino acids). The synthesis of a chain starts when a free (unattached) ribosome begins to move along a molecule of messenger RNA (mRNA) in the cytoplasm.Once a small number of amino acids have been incorporated into the chain, large molecules in the cell "inspect" the chain. Certain sequences of amino acids are recognized as marking the chain for synthesis in the lumen of the rough endoplasmic reticulum (ER).If the chain has one of these sequences, the mRNA and ribosome are moved to the ER and the ribosome is fixed in the ER membrane in such a way that the mRNA remains in the cytoplasm but the polypeptide chain is in the lumen of the ER. It is in the lumen that the chain is completed, and subsequently coils and folds to form the finished polypeptide.If, on the other hand, the chain does not have one of these marker sequences, synthesis of the chain and its subsequent coiling and folding all take place in the cytoplasm.
How can one hormone molecule lead to the synthesis of thousands of enzyme molecules?
The mechanism through which a single hormone molecule triggers the generation of thousands to millions of enzyme molecules is called biological signal transductionThis process begins with a hormone molecule binding to its receptor on the surface of a cell. Following this, there is a signal generated.Inmolecular biology, asignal is said to be generated when a certain inter-cellular or membrane-bound protein becomes phosphorylated and triggers further downstream events.The ultimate result (or the end step) ofthis signal transduction pathwayis to up-regulate thetranscription of a specific enzyme-coding gene. When many copies of thisgene are transcribed,several molecules of the enzymeswill be produces.

What does a Lewis dot show?
Lewis dot structures show how an atom's electrons work together in a certain molecule. They also show what a certain molecule will look like.
What term descrives a substance that is made when two or more different atoms bond together in a certain ratio?
The smallest such substance is a molecule, or a formula unit of an ionically bonded compound. Any amount of such a substance also satisfies the requirement given.
What is chernosynthesis?
Synthesis of carbohydrates from carbon dioxide and water using energy obtained by chemical oxidation of simple inorganic compounds. This form of synthesis is limited to certain type of bacteria and fungi.
After a cell was treated with a certain chemical the ribosomes stopped functioning which cell activity was immediately affected by this change in ribosome funcation?
synthesis of proteins. And since the synthesis of proteins is necessary for maintenance of the cell, most of the processess will be stopped afterwards.
Does a chemical formula represent one molecule of a certain compound?
Yes
