What is the role of DNA, mRNA, rRNA, tRNA, and ribosomes in protein synthesis? What proteins do B cells produce? Does elongation in ribosomes use energy? What items found in the cytoplasm, and not coming from the nucleus, would a cell need to make protein?
RNA is needed in a cell for protein synthesis. A gene sequence is converted to mRNA (messenger RNA) which transports information outside of the nucleus. In the cytoplasm, the mRNA is 'read' by ribosomes (made up of rRNA (ribosomal RNA) and proteins) to build the proteins. tRNA (t...
tRNA, or transfer RNA, is the "decoder" of the mRNA message during protein translation. After transcription, tRNA is extensively modified to include nonstandard bases such as pseudouridine, inosine, and methylguanosine. By themselves, ribosomes cannot form a protein when the mRNA makes contact. T...
Ribosomes themselves consist of about one-third protein by mass; the other two-thirds consist of a specialized form of ribonucleic acid (RNA) calledribosomal RNA, or rRNA. (Soon, you'll meet the other two major members of the RNA family, mRNA and tRNA.) Ribosomes are one of four distin...
What is the difference between mRNA, tRNA, and rRNA? Do host cell proteins get on the viral envelope? Which type of protein does DNA wrap around so that it can be packaged in a cell? What is the difference between chromatin and a nucleosome? What is the differe...
The main role of the ribosome is to translate proteins from mRNA transcripts. The ribosome itself is made up of rRNA, and it uses tRNA to produce...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...
Ribosomes:Ribosomes are small electron-dense particles in the cytoplasm and rough endoplasmic reticulum of cells. Each ribosome is composed of rRNA and protein.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our...
central dogma of small-scale biology: DNA makes mRNA, and mRNA makes, or at least carries instructions for, proteins. In the grand scheme, the ribosome is the only part of the cell that simultaneously relies on all three standard types of RNA (mRNA, rRNA and tRNA) in order to function....
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 functions of the three types of RNA? 1- mRNA. 2- tRNA. 3- rRNA. What is the function of tRNA? Select one: a. picks up amino acids from the cytoplasm and delivers them to ribosomes b. creates RNA strands based on DNA templates c. form ribosomes and build proteins d. del...
