What is the mirrorlike copy of DNA that moves from the nucleus to the ribosome?
The mirrorlike copy of DNA that moves from the nucleus to the ribosome is called messenger RNA (mRNA). It carries the genetic information from DNA to the ribosome, where it is used as a template for protein synthesis.
What is making a real protein?
To make a protein, a cell goes through two processes, the first one is transcription and the second is translation. In the first stage, DNA helicase unwinds and unzips the two strands of a DNA double helix. Then DNA polymerase comes in and helps make a complementary strand called messenger RNA of mRNA. this mRNA is then cut up to the bare essentials, thus containing pretty much only the nucleotides coding for genes. Splicosomes are the molecules that do this cutting, known as splicing, which then makes the mRNA ready for action. The mRNA then travels outside of the nucleus, and finds a transfer RNA of tRNA molecule. The next step is translation, in which the actual building of the protein takes place. First off, the mRNA molecule is floating around, until it meets a ribosome. This ribosome is the site at which this mRNA will meet a tRNA molecule, containing a nucleotide sequence complementary to that of the mRNA. This tRNA has this nucleotide sequence at one end, and an amino acid on the other end. This amino acid is then put into the ribosome, into the A site of the ribosome. It then moves to the P site, where the polypeptide chain, or building of the protein is actually taking place. This amino acid is then adjoined to the chain, and is then part of the protein molecule. Once all of the necessary amino acids are joined in, the protein moves to the E site, where it exits the ribosome. This molecule is then complete, and will then proceed to the part of the cell where it is needed, and will start to function.
What moves during protein synthesis mRNA or rRNA?
During protein synthesis, mRNA carries the genetic information from the DNA in the nucleus to the ribosome in the cytoplasm, where the protein is synthesized. rRNA, on the other hand, is a structural component of the ribosome and plays a role in catalyzing the formation of the peptide bonds between amino acids during translation.

What are linked to make proteins as a moves along the mRNA transcript?
Amino acids are linked together to form proteins as the ribosome moves along the mRNA transcript. Transfer RNA molecules bring specific amino acids to the ribosome, where they are added to the growing protein chain based on the mRNA codons being read. This process continues until a stop codon is reached, leading to the completion of protein synthesis.
Observe how the mRNA interacts with the ribosome in the simulation. How is this interaction similar to what actually happens in translation?
The interaction between mRNA and ribosomes in the simulation is meant to reflect the process of translation that occurs in cells. During translation, the ribosome uses the information stored in the mRNA molecule to synthesize a protein. The ribosome moves along the mRNA molecule and reads its codons (sets of three nucleotides) to determine which amino acids should be added to the growing polypeptide chain. In the simulation, the mRNA molecule is represented as a linear sequence of codons, and the ribosome is represented as a moving object that recognizes and interacts with the codons. The ribosome moves along the mRNA and recognizes each codon by binding to it. This interaction is similar to what happens in real cells, where the ribosome recognizes codons by binding to specific sites on the mRNA molecule. In the simulation, the ribosome can also interact with tRNA molecules, which bring the correct amino acids to the ribosome for incorporation into the growing polypeptide chain. This is similar to what happens in real cells, where tRNA molecules bring the correct amino acids to the ribosome for use in protein synthesis. Overall, the interaction between mRNA and ribosomes in the simulation is meant to closely resemble the process of translation that occurs in cells.
Where is messenger RNA attached during protein construction?
Messenger RNA (mRNA) is attached to a ribosome during protein construction. The ribosome acts as the site where the mRNA is read and translated into a protein. As the ribosome moves along the mRNA, it synthesizes the corresponding protein based on the genetic information encoded in the mRNA molecule.
Where does tRNA move after this bonding of lysine to the polypeptide?
After bonding lysine to the polypeptide chain, the tRNA moves away from the ribosome as it is no longer needed for the process of translation. The ribosome then moves along the mRNA to the next codon, where another tRNA molecule carrying the next amino acid will come in to continue building the polypeptide chain.

The mirrorlike copy of DNA that moves from the nucleus to the ribosome is called messenger RNA (mRNA). It carries the genetic information from DNA to the ribosome, where it is used as a template for protein synthesis.
Where does the process of translation do in mRNA?
The newly spliced mRNA binds to a ribosome. tRNA molecules migrate towards the ribosome, these tRNA molecules carries a specific amino acid. The ribosome allows two tRNA molecules into the ribosome at a time. The tRNA molecules have complementary anti-codons to the codons present on the mRNA strand. Two tRNA move into the ribosome and their anti-codons join to complementary codons on the mRNA strand. As one molecule leaves the ribosome, its amino acid forms a peptide bond with an amino acid on the adjacent tRNA molecule, with the help of ATP and an enzyme. As the ribosome moves along the the mRNA strand, a polypeptide chain is created. The ribosome stops reading the mRNA strand when it reaches a stop codon.

What are in biology the steps of translation?
What do we get from Transcription?Processed mRNA (methylated cap, poly-A tail, introns removed, exons rearranged)What else do we need?RibosomestRNAAmino acidsAmino acyl tRNA synthasePeptidyl transferaseWhat are we trying to make?ProteinsHere are the steps for translation, rather briefly:1) Amino acyl tRNA synthase matches amino acids to their respective tRNA molecules.2) Activated tRNA-amino acid complexes are moved to the ribosome (either in the cytoplasm or on the Rough Endoplasmic Reticulum). Processed mRNA also moves to the ribosome.3) Ribosome fixes onto the mRNA strand and detects the start codon AUG.4) When it hits AUG, the tRNA coding for Methionine will enter the A site of the ribosome. Here, the tRNA carries out complementary base pairing with the mRNA strand.5) The Met-tRNA moves to the P site. The next codon (3 bps) are read and the appropriate tRNA molecule binds to it in the A site.6) The Met amino acid from the P site then binds to the 2nd amino acid from the A site, catalysed by peptidyl transferase. The first tRNA molecule leaves the ribosome through the E site. The second tRNA molecule moves into the P site.7) The step above is repeated until the ribosome gets to the STOP codon. When this occurs, the ribosome leaves the mRNA strand and the mRNA strand disintegrates. The completed polypeptide chain folds into its secondary, tertiary and quarternary structures and forms proteins and enzymes.
What happens to water molecules that move with higher energy?
The faster a molecule moves, that hotter it becomes. If water becomes hot enough, it evaporates into steam.
Explain how a protein molecule is synthesized from mRNA?
The mRNA brings the necessary code from the DNA to the ribosome. Meanwhile, the tRNA is bringing the anticodon to translate the codon on the mRNA, along with an amino acid which will be connected in a chain by peptide bond to form a protein. Once the tRNA and mRNA aligns themselves into the ribosome, the translation begins and more tRNAs come and go to dump their amino acids. The amino acids are all connected until a large chain is formed. The chain is then modified further to become a functional protein.
What is the role of tRNA durning translation?
tRNA, or transfer RNA, plays a crucial role in translation by bringing amino acids to the ribosome. Each tRNA molecule carries a specific amino acid and has an anticodon that can base pair with the codon on the mRNA. This allows for the accurate incorporation of amino acids into the growing polypeptide chain.
