The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information encoded in DNA and encodes it into mRNA, which heads out of the cell’s nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins. RNA polymerase is necessary for the process to occur.

What does synthesis protein mean?
= Protein Synthesis = ----Legend:Process whereby DNA encodes for the production of amino acids and proteins. This process can be divided into two parts:1. TranscriptionBefore the synthesis of a protein begins, the corresponding RNA molecule is produced by RNA transcription. One strand of the DNA double helix is used as a template by the RNA polymerase to synthesize a messenger RNA (mRNA). This mRNA migrates from the nucleus to the cytoplasm. During this step, mRNA goes through different types of maturation including one called splicingwhen the non-coding sequences are eliminated. The coding mRNA sequence can be described as a unit of three nucleotides called a codon. 2. TranslationThe ribosome binds to the mRNA at the start codon (AUG) that is recognized only by the initiator tRNA. The ribosome proceeds to the elongation phase of protein synthesis. During this stage, complexes, composed of an amino acid linked to tRNA, sequentially bind to the appropriate codon in mRNA by forming complementary base pairs with the tRNA anticodon. The ribosome moves from codon to codon along the mRNA. Amino acids are added one by one, translated into polypeptidic sequences dictated by DNA and represented by mRNA. At the end, a release factor binds to the stop codon, terminating translation and releasing the complete polypeptide from the ribosome. One specific amino acid can correspond to more than one codon. The genetic code is said to be degenerate.

What are feeder roads?
they are roads that brings traffic to a major road
What type of animal brings chocolate presents at Easter time?
An easter bunny!!
Does Jane Goodall still have her chimpanzee?
Yes she sometimes brings it when she is speaking to an audience
What type of RNA is involved in protein synthesis?
Firstly, messenger RNA (mRNA) that takes the message from the DNA to the ribosomes. Secondly ribosomal RNA (rRNA) which helps catalyze the synthesis of the protein when transfer RNA (tRNA) brings a single amino acid to the ribosome for insertion into the growing polypeptide chain.
What is the ribosomes functions?
Protein synthesis is the process done by ribosomes. Ribosomes provide surface to synthesis.Protein synthesis is the process done by ribosomes. Ribosomes provide surface to synthesis.
Organelles that are the site of protein synthesis?
The organelle which is the site of protein synthesis for the cell is the ribosome. DNA in the nucleus has the code for building protein, mRNA picks up the code and brings it to the ribosome where the code is translated into a sequence of amino acids that makes up specific proteins.
This is one form of RNA that transports a specific amino acid to a ribosome during protein synthesis.?
Transfer RNA (tRNA) is responsible for carrying amino acids to the ribosomes so that protein synthesis can occur.
What type of RNA associates with proteins to form ribosomes?
Messenger RNA (mRNA),which carries the transcript from the DNA ,and transfer RNA (tRNA) which carries the amino acids.
What does messenger RNA become attached to in cytoplasm?
I assume you are talking about protein synthesis? Good. Messenger RNA (mRNA) is ejected from the nucleus after it has made a copy of the base pairing sequence for that particular gene (to produce a protein) via a nuclear pore. The mRNA comes into contact with Ribosomal RNA (rRNA) in the cytoplasm of the cell. The Transfer RNA (tRNA) then brings along the correct amino acids as indicated by the sequence of the mRNA which is attached to the rRNA. The mRNA is passed between the sub units of the ribosome and the tRNA brings along the amino acids in the correct sequence until a codon is present (tells it to stop). The amino acids are then joined by a condensation reaction with peptide bonds to form a polypeptide chain and eventually a protein. Amazing stuff huh?!
What does RNA A messenger do during protein synthesis?
Depending on what RNA you're talking about, it serves a different, but individually crucial role in protein synthesis. The mRNA brings the code needed for translation. The tRNA brings the anticodon to match with the codon on the mRNA along with amino acids to form proteins. The rRNA, which combines with proteins to form ribosomes, serves to fit the mRNA and tRNA together to form a functional protein.
Brings amino acids together to build a protein in the ribosomes?
tRNA
What does the ribosomes do in a animal cell?
A ribosome is a molecular machine that coordinates protein assembly. Ribosomes are composed of several proteins with tightly coiled RNA (called ribosomal RNA or rRNA) wrapped around them. Ribosomes consist of two parts, the large and small subunits, which clamp around the mRNA that needs to be translated.A ribosome brings together correctly the mRNA, which needs to be translated, and the tRNA, which assists in the translation process, to come together correctly. During translation, tRNA molecules carrying amino acids are positioned in the ribosome’s two docking sites. Afterwards, this machinery can disassemble and be reused many times. In the upcoming animation, you will see a ribosome assembling a polypeptide chain, a future protein.
What does the ribosoms do?
The ribosome are the " workbench " on which proteins are synthesized. mRNA is threaded through this catalytic organelle while tRNA brings single amino acids that are then linked in a long polypeptide which is on it's way to becoming a mature protein.
What is an adapter molecule which brings amino acids to the ribosomes to build a protein?
