When the ribosome moves to the right what happens to the first tRNA molecule?
The first tRNA molecule is released as the ribosome moves to the right during translation. It is no longer needed once it has delivered its amino acid to the growing polypeptide chain.
Which codon engages a ribosome to start translating mrna molecule?
because of the big penises all around it cumming on it. That's Why.
What is the first step in protein is called?
The first step in protein synthesis is called transcription. During transcription, the DNA sequence of a gene is used to create an mRNA molecule that carries the genetic information from the nucleus to the ribosome in the cytoplasm.
How does the cell make the first ribosom?
The first ribosome is formed through a process called ribosome biogenesis, which occurs in the nucleolus of the cell. Ribosomal RNA (rRNA) is synthesized from ribosomal DNA (rDNA) and combined with ribosomal proteins imported from the cytoplasm. This assembly creates the small and large subunits of the ribosome, which are then transported to the cytoplasm where they combine to form a functional ribosome, essential 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 happens in First Steps?
The mRNA molecule attaches to a ribosome where it will be translated.
What steps happen first in translation?
The mRNA molecule attaches to a ribosome where it will be translated.
When the ribosome moves to the right what happens to the first tRNA molecule?
The first tRNA molecule is released as the ribosome moves to the right during translation. It is no longer needed once it has delivered its amino acid to the growing polypeptide chain.
How did the P site of the ribosome get its name?
The P site of the ribosome stands for peptidyl-tRNA site, as it is where the peptidyl-tRNA molecule is positioned during protein synthesis. The naming convention for ribosome sites comes from the type of molecule that occupies each site during translation.
At the beginning of translation the first tRNA molecule?
At the beginning of translation, the first tRNA molecule, carrying the amino acid methionine, binds to the start codon (AUG) on the mRNA. This tRNA molecule recognizes the start codon through base pairing and initiates the assembly of the ribosome on the mRNA strand.

What is a ribosome's structure?
A ribosome is composed of two parts known as the large and small subunits. Each of these is a combination of protein and a type of RNA known as rRNA. At the beginning of translation, the two subunits form a structure around the mRNA molecule as the first tRNA (the one matching the first methionine or fMet) arrives. The completed ribosome has niches that hold up to three tRNAs at a time. Because a cell has so many ribosomes at any one time, rRNA is the most common type of RNA found in cells.
Which is the first event in translation in eukaryotes?
ANSWER: the small subunit of the ribosome recognizes and attaches to the 5' cap of mRNA ------------------------------------------------------------------------------------------------------- This answer bellow, appears all over the internet, but its wrong. I just took a quiz. -base pairing of activated methionine-tRNA to AUG of the messenger.
