What is the role of each organelle in a bacteria cell? (a) Describe the structure of the ribosome. (b) Describe its function. What are the functions of ribosomes and tRNAs during protein translation? Explain the role of the nucleolus in protein synthesis. ...
Ribosomal proteins andribosomal RNA (rRNA)together make up the two subunits of the ribosome. Surprisingly, the nucleic acid portion contributes to most of the structure of the ribosome while the proteins fill in gaps and amp up protein synthesis, which would occur much more slowly without them. ...
What are the four bases of RNA? What are the components of a nucleotide? If only 1-3 percent of the RNA is mRNA, what is the rest of the RNA made out of? Which bases bind together in RNA? What type of RNA carries instructions from DNA in the nucleus to the ribosome in the cytop...
I am so intrigued by all of the workings of cells. It's fascinating that such tiny things are what make up human beings. It's so interesting! Byelizabeth2— On Feb 02, 2011 That is so crazy that it's now possible to create ribosomes! It's kind of like something you would see on...
I am so intrigued by all of the workings of cells. It's fascinating that such tiny things are what make up human beings. It's so interesting! 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...
mRNA fragments of∼30 nucleotides that result from nuclease treatment of translating ribosomes. These are mRNA regions that are protected by the ribosome as the mRNA is decoded to a protein sequence. Upstream open reading frames (uORFs). ORFs in the 5′ leader region of a characterized mRNA...
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 ...
translation. Before they can help coordinate this task, they themselves have to be put together, because ribosomes only exist in their functional form when they are actively operating as protein-manufacturers. Under resting circumstances, ribosomes break up into apair of subunits, one large and ...
aEukaryotic ribosomes have 60S and 40S subunits that combine to form an 80S ribosome, which is a little larger than bacterial ribosomes. Eukaryotic核糖体有60S和40S结合形成80S核糖体,是少许大于细菌核糖体的亚单位。[translate] a不要给人生留下任何遗憾 Do not leave behind any regret to the life[...
Then the rRNA and proteins are assembled into two subunits, one large and one small, that will eventually combine to create a single ribosome. These subunits leave the cell's nucleus via pores found in the nuclear membrane. They enter the cytoplasm of the cell, where they come together to ...
