The right matches are:
2nd. ==> A peptide bond...
4th. ==> Once a protein...
3rd. ==> A chain of amino acids...
1st. ==> The first codon of mRNA...
Gene expression is the mechanism that groups together all the processes that lead to a functional product of the gene.
Transcription is the process of obtaining a strand of RNA from a strand of DNA.
Once the messenger RNA is mature, it is exported outside the nucleus, in order to recruit the ribosomes and proceed with the translation.
The nucleotides are read in groups of 3, the codons. Each codon encodes an amino acid, or allows to initiate or stop the translation.
Once the ribosome has settled on the mRNA strand, it will go through it until it finds the first AUG codon to start the translation. The ribosome will then read each codon, which will result in the production of an amino acid. This produces the production of an amino acid chain, in other words a protein. The translation ends when the ribosome encounters a stop codon.
So, at the end of this process, we get a functional product of the gene: a protein.
The steps of the translation that lead to gene expression is the attachment of mRNA to tRNA, peptide bond formation, chain of amino acid forming proteins and the expression of the gene for a specific trait.
How is a gene expressed?
The biological process of protein formation with the help of amino acids and mRNA is called translation. The amino acids produced are linked by the peptide bonds to create proteins.
Gene expression is a process of the formation of active proteins required by the body for functional and structural roles. The process of transcription and translation forms the amino acid and the proteins needed for gene formation.
In the transcription process, the mRNA start codon binds to the anticodon present on the tRNA so that the chain of amino acids can be created.
The amino acids thus formed are joined together by peptide bonds and the chain of amino acids creates the proteins. The active protein formed codes for a particular trait in the form of genes that are specific and can be dominant or recessive.
Therefore, the products of the translation lead to gene expression.
