The A-site of the ribosome is where lengthening of the polypeptide chain happens during translation by adding amino acids using dehydration synthesis.

Which is true of protein synthesis processes?

If a molecule of DNA read ATTGCA, the complimentary mRNA would read TAACGT.

Essay A: This essay must be written in full sentences at the College level. If you have covered all parts, you will likely have 8-10 sentences or 2 significant paragraphs. Make sure you are detailed and define all relevant terms and explain their role in the process.   An action potential is a signal that causes a cell to increase its intracellular calcium. In this essay, explain where this intracellular calcium comes from in a skeletal muscle fiber and then follow the domino effect of this influx through the power stroke. Hint: be detailed about the activity of the thick and thin filaments and the process of phosphorylation. (HINT Assume the action potential has ALREADY been received and is moving down a membrane at peak voltage… you are dealing with what calcium does inside the cell.)  

A ribsome can read 4 codons at a time.

Which is NOT true about mitochondria?

Skeletal Muscle cells are in Go.

If the DNA triplets read CAT-GAC, the corresponding anticodons would read CAU-GAC.

Which is not true about embryonic differentiation of tissues?
