Which cell organelles is responsible for producing proteins?
Protein synthesis is made from a process that consists of some organelles. The process begins with DNA, in the first organelle the nucleus. In the nucleus DNA is made into RNA through a process called transcription. After transcription finishes, mRNA leaves the nucleus, it interacts with other types of RNA. Transfer RNA (tRNA) participates in translation by picking up amino acids and aligning them on the next organelle the ribosome in the exact order specified by the mRNA. The two ribosomal subunits mRNA and a tRNA carry methionine and bind together for the process called initiation. During elongation amino acids come together by peptide bonds and lengthen the polypeptide chain one link at a time. During termination ribosome reach a stop signal in the mRNA and a termination factor binds to the ribosome and stop protein synthesis, after which the new polypeptide chain is released and the protein is made.
MRNA is formed in the process of?
Once the DNA is unwinded and we now have two separate template strands. A RNA polymerase attaches to each of the strands and allows a new sense strand to build its complementary strands. This sense strand is the mRNA. +dna provides a template for rna polymerase.
What is a ribosome and what does it do?
A ribosome is a two subunit complex made of protein and catalytic RNA that unites as one unit when mRNA docks on the large subunit. Ribosomes are the " workbench " on which proteins are synthesized. The ribosome crawls along the mRNA and knits together a polypeptide chain from the free amino acids brought to the ribosome by tRNA.
Which one of the following lists the steps involved in the production of new proteins in the appropriate order and correctly describes each step?
The below equation will show you that how proteins froms.a) DNA -------> b) RNA --------> c) ProteinIn the step a. :- The DNA is transcribed by RNA polymerase and forms RNA or mRNA or Messanger RNAIn step b. :- This mRNA is then translated by Ribosome and forms the protein by attaching the specific amino acid in a chain fashion with the help of tRNA ( This tRNA fetches the specific amino acid to the ribosome from the cytoplasm).In step c.:- The protein is ready but not for still it is meaning less for a cell so it undergoes in some modifications, thats we call as Protein modification.
What is the organelle that starts the process of making proteins?
The organelle that starts the process of making proteins is the ribosome. Ribosomes are responsible for protein synthesis, where they read the messenger RNA (mRNA) and assemble the amino acids into a protein chain according to the genetic code.

What are the stages called collectively that represents the backbone of molecular biology?
This can be answered referring to the molecular biology "dogma", that is, DNA forms mRNA during transcription, mRNA is translated into a protein during the translation process. Besides this dogma sequence, DNA molecule forms a new DNA through the replication mechanism.
Is new wine alcoholic?
Yes, new wine is alcoholic because it is made through the fermentation process, which produces alcohol.

Briefly describe how the process of translation is started?
In the cytoplasm, rRNA binds to the "start" codon of a mRNA molecule. Next, a tRNA molecule with the complimentary anticodon binds to the mRNA start codon and releases an amino acid. As the mRNA moves through the rRNA, new tRNA's come along and bind to the mRNA, adding a new amino acid each time. Eventually a "stop" codon is reached, and the rRNA, mRNA, and tRNA break apart, releasing a long chain of amino acids which will fold into a protein.
Where is new mRNA produced?
mRNA is produced inside the nucleus of the cell after transcription has occurred.
What is protein systhesis?
Protein synthesis is the process by which cells make proteins, using instructions encoded in their DNA. It involves the transcription of DNA into messenger RNA (mRNA) and the translation of mRNA into a specific sequence of amino acids that form a protein. This process is essential for the growth, maintenance, and repair of cells in the body.

How do you know what to write for each of the new mrna codes?
mRNA is the complementary of the DNA strand that it attatches to, and replace T with G
Haw does antisense technology work?
Antisense technology is based on stopping the production of a protein. In order for a protein to be formed, the mRNA has to be translated (read by the ribosomes). The happens in the cytoplasm. There are stretches of nucleic acid bases called cDNA that are complimentary to specific mRNA sequences. These cDNA molecules can bind to the mRNA molecules and inactivate them. When mRNA is inactivated, it cannot be translated into a protein and a protein will not be formed. Since every protein is made by a certain mRNA, by inactivating the mRNA using cDNA molecules, the production of the protein can be stopped. This process is called mRNA silencing or antisense technology
