What do the ribosomes do in a plant cell?Plant Cells:Plants are eukaryotes which means their cells have a membrane-enclosed nuclei. Their cells also contain chlorophyll which makes plants green and allows the plants to use sunlight to make food. Plant cells have a rigid cell wall in ...
What are ribosomes in a cell? A ribosome isa cellular particle made of RNA and proteinthat serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence ...
What do ribosomes do in protein synthesis? What does a DNA-binding protein do? Where do the instructions for protein synthesis come from? What is a promoter in protein synthesis? Which organelle is the site where amino acids are synthesized into proteins?
Ribosomes do not exist in their fully assembled form until they are called upon to do their jobs. That is, the subunits spend all of their "leisure time" alone. So when translation is getting underway in a particular part of a given cell, ribosome subunits in the vicinity are starting t...
That is so crazy that it's now possible to create ribosomes! It's kind of like something you would see on a movie, not real life! What will they be able to do next, build a human being? I think all of these scientific discoveries are amazing, and I'm sure they help us out a...

Mature miRNAs impede gene translation by binding at complementary messenger RNA sequences, thereby initiating mRNA cleavage or obstructing mRNA incorporation in ribosomes. More than 2000 human miRNAs have been identified [7, 8], potentially regulating the transcription of the 21,000 human protein-...
classification known as _prokaryotes,_ which have cells that include a bare minimum of essential components: genetic material (i.e., DNA), a cell membrane to keep the whole thing together, cytoplasm (the gel-like matrix forming the majority of the cell's mass) and ribosomes, which ...
Ribosomes play a key part in protein synthesis, the process that generates organic tissue. Genetic instructions for the creation of new proteins come from mRNA. They always have two subunits which interlock and behave as a single entity. The exact type of ribosome found within a cell can ...
A method for fractionating ribosomes that are bound to mRNAs by velocity centrifugation of cell extract on sucrose gradients, allowing for the separation of mRNAs that are associated with one ribosome (monosome) from those being translated by multiple ribosomes (polysome). Sucrose gradient fractionat...
