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.
Where does the attachment of a mRNA molecule to a ribosome take place?
The attachment of a mRNA molecule to a ribosome takes place in the cytoplasm of a cell. The ribosome binds to the mRNA at the start codon to initiate protein synthesis. This process is essential for translating the genetic information encoded in the mRNA into a specific protein.
What carries genetic information from the nucleus to the ribosome?
Messenger RNA (mRNA) carries genetic information from the nucleus to the ribosome. It is synthesized during transcription in the nucleus and then transported to the cytoplasm where it serves as a template for protein synthesis at the ribosome.
What is the decoder of mRNA?
The decoder of mRNA is the ribosome, a complex cellular machinery that reads the sequence of nucleotides on the mRNA and translates it into a sequence of amino acids, forming a protein molecule. The ribosome does this by matching each three-nucleotide codon on the mRNA with the corresponding tRNA carrying the complementary anticodon and specific amino acid.
What 3 types of RNA that help to build proteins?
There are 3 types of RNA: mRNA; rRNA; tRNA. mRNA, or Messenger RNA, is a copy made from a template piece of DNA, this will encode (every 3 nucleotides makes up a codon which can be read as an amino acid, for example CGA is the codon for an arginine) for the protein that you wish to make. rRNA, or Ribosomal RNA, is made of 2 subunits, a 50s and 30s (s is just a measure of size), that are combined to make a ribosome. A ribosome is the site in which the protein is synthesized (it contains all the elements necessary to make protein). tRNA, or Transfer RNA, is what actually reads the mRNA and makes the protein by recruiting and adding the necessary amino acid that the mRNA codes for.
How can lots of ribosomes speed up making proteins?
A single mRNA molecule can have more than one ribosome translating it at a time. Another ribosome can attach and start translation before the previous one has finished. Therefore the more ribosomes there are the more proteins made from a single transcript at one time.

How do mRNA and tRNA work together during protein synthesis?
The mRNA brings the message that was transcribed by the DNA to the ribosome, while the tRNA brings the anticodon to translate the message, along with the amino acid which bonds to form a polypeptide chain. The chain is further developed into a functional protein .
What organelle receives instructions from the hereditary material on how when and in what order to make proteins in a cell?
messenger RNA (mRNA) is transcripted from DNA. mRNA takes the genetic information on how to synthesis a protein out of the nucleus to a ribosome (composed of ribosomal RNA). mRNA is read (translated) by ribosome. transfer RNA (tRNA) brings in amino acids and the ribosome connects them together to make proteins. it's a little more technical than this, though.
What happens to ribosomes during protein synthesis?
Ribosomes are the site of protein synthesis in the cell. They read the messenger RNA (mRNA) transcript and use it as a template to assemble amino acids into a polypeptide chain according to the genetic code. Ribosomes are composed of two subunits (small and large) that come together during translation and dissociate after protein synthesis is complete.
Explain the process of translation and tRNA anticodons?
In short, translation is the process of ribosomes reading mRNA and using tRNA to gather the amino acids specified by the mRNA. The tRNA anticodons are complementary to the codons (three nucleotide sequence that represents an amino acid) on mRNA and allow them to be identified by the ribosome. In detail, translation is the second process of making a protein or polypeptide, the first being transcription. During translation, the mRNA leaves the nucleus and moves to the ribosome, usually located on the Rough ER (endoplasmic reticulum) or in the cytoplasm of the cell. The ribosome consists of two subunits, a large and small one. Initiation factors take the mRNA to the small ribosomal subunit, where other initiation factors move the tRNA to the first codon (three nucleotides sequence that represents a particular amino acid.) Then, the large ribosomal subunit attaches to the small subunit, encasing the mRNA and tRNA. The ribosome contains three distinct areas that the tRNA can occupy in the ribosome: the A site, where tRNA enters and receives the existing amino acid chain, the P site, where it comes in contact with the codons on the mRNA, and the E site, where the tRNA prepares to leave the ribosome. The first tRNA enters the P site and always carries N-formylmethionine (fMet), and all subsequent tRNAs enter the A site, then move to the P site then E site. Since tRNA is reusable and can only carry a particular amino acid, its possesses anticodons that represent the amino acid it carries. The first codon on mRNA is always a 'start' codon AUG (amino acid Methionine.) The ribosome moves down the mRNA and 'reads' each mRNA codon and finds the tRNA with the complementary anticodon (for example, if a codon on mRNA was GGG (Glycine), the complementary tRNA would have an anticodon of CCC and would be carrying the amino acid Glycine.) At the end of the mRNA, a stop signal is read by the ribosome and a release enters the A site instead of tRNA, prompting the ribosome to disassemble and be made available for more mRNA. The stop codons (also known as nonsense codons) are UAA, UAG, and UGA; they do not translate into any amino acid.
What would happen to translation if a ribosome skipped one or more codons?
If a ribosome skips one or more codons during translation, it can result in a frameshift mutation. This mutation can alter the reading frame of the mRNA sequence, leading to the synthesis of a completely different protein with potentially nonfunctional or altered properties. The severity of the impact depends on where in the mRNA sequence the ribosome skips codons.
What is the nucleous's function?
The nucleolusâ??s primary function is to synthesize mRNA, rRNA and ribosome in living cells. According to scientists, more than 50% of RNA is synthesized in the nucleolus.
