17 lut 2023 · The process of protein synthesis occurs in two steps: transcription and translation. In the first step, DNA is used as a template to make a messenger RNA molecule (mRNA). The mRNA thus formed, exits the nucleus through a nuclear pore and travels to the ribosome for the next step, translation.
In prokaryotic cells, transcription (DNA to mRNA) and translation (mRNA to protein) are so closely linked that translation usually begins before transcription is complete.
Relate protein synthesis and its two major phases to the central dogma of molecular biology. Identify the steps of transcription, and summarize what happens during each step. Explain how mRNA is processed before it leaves the nucleus. Describe what happens during the translation phase of protein synthesis.
This 3D animation shows you how the DNA code is transcribed into messenger RNA and then translated into a protein. Starting in the nucleus, we see how the DNA code is converted to messenger RNA by the process of transcription.
Our DNA carries the genetic instructions our cells need to make proteins. To make these proteins, cells first copy the specific genetic instruction in their DNA into a messenger molecule called RNA. This is then converted to the final protein product. This process is called gene expression.
Describe the process of and key components required for translation. Differentiate between types of DNA mutations, and predict the likely outcomes of these mutations on a protein’s amino acid sequence, structure, and function; Compare and contrast prokaryotic and eukaryotic transcription and translation; The Central Dogma
