What is the mirrorlike copy of DNA that moves from the nucleus to the ribosome?
RNA
What moves during protein synthesis mRNA or rRNA?
mRNA moves out of the core (however, the mRNA is read by the ribosome, which is made up partly of rRNA; so while the ribosome slides along the mRNA, its rRNA moves also)
What Moves along the mRNA and helps form the peptide strand?
ribosome
What will happen after the ribosome joins the methionine and phenylalanine?
The ribosome breaks he bond between methionine and it's tRNA. The tRNA floats away from the ribosome, allowing the ribosome to bend to another tRNA. The ribosome moves along the mRNA, binding new tRNA molecules and amino acids.
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.
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 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 is the function of ribosome RNA?
rRNA is a massive molecule consisting of two parts; a small section, and a large section. It is between these two sections that the mRNA fits, and into the large selection that the tRNA complexes (with attached amino acids) are taken. rRNA molecules have two main binding sites. When a tRNA molecule is bound, the mRNA molecule moves along one space, and another tRNA molecule binds. When this happens, the amino acids at the ends of the tRNA molecules are very close together, and a peptide bond forms. The mRNA then moves along again and the first tRNA molecule breaks away.

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 organelle moves protein around the cell with transport vesicles and has attached ribosome?
Transport Vessicle
What are linked to make proteins as a moves along the mRNA transcript?
Amino acids are linked to make proteins as a ribosome moves along the mRNA transcript.
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.
