Ribosomes are molecular machines that synthesize proteins in the cell. Recent biochemical analyses and high-resolution crystal structures of the bacterial ribosome have shown that the active site for the formation of peptide bonds – the peptidyl-transferase center – is composed solely of rRNA. Thus...
“Errors in ribosome assembly severely reduce the capacity of our cells to make proteins. These are for example proteins that convert the energy from the food we eat into energy coins that the body can use to run all sorts of cellular processes. Now, if the mitochondrial ribosome does not w...
Once all of your organelles are securely attached to the base of your model, label the organelles. Toothpicks and stickers make great labels, and they let everyone know what's what on your cell model. A Deeper Understanding Building a cell model should deepen your understanding of the cell a...
Explain the process of protein synthesis in detail and how it links to making mRNA. What are our natural complement proteins? Why are they necessary? Why are ribosomes made? Explain how a nucleotide base might be changed without changing the protein?
The proteins are formed through translation by specific cellular organelles called ribosomes. However, these proteins are not yet functional, but they...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
DNA carries the information for making all the cell's proteins. These proteins implement all the functions of a living organism and determine the organism's characteristics. When the cell reproduces, it must pass all of this information on to the daughter cells. Before a cell can reproduce, ...
The genetic code is the code found in mRNA that gives instructions for how to make our proteins. Proteins are important because they make up the physical structure of our cells and our bodies. The protein keratin makes up our nails and hair. The protein melanin gives our skin pigment. There...
This main part has all of the necessary components of the cell, such as the nucleus (which contains DNA), endoplasmic reticulum and ribosomes (for building proteins) and mitochondria (for making energy). If the cell body dies, the neuron dies. Axon . This long, cablelike projection of ...

In neurons, the quantities of mRNAs and proteins are traditionally assumed to be determined by functional, electrical or genetic factors. Yet, there may also be global, currently unknown computational rules that are valid across different molecular speci
