<u>Using protein synthesis with two main processes :</u>
<u>Transcription</u>
<u>Translation</u>
Explanation:
<em>All organisms make proteins in essentially the same way. </em>
process of making protein (Gene Expression) has two main stages: transcription and translation.
TRANSCRIPTION:
Structures in the cell identify <em>the start and end of a gene and read the DNA sequence between them (the order of A, C, G and T bases within the gene).</em>
A molecular message (an mRNA molecule) is produced that echoes the sequence of the gene itself. In most respects, mRNA looks similar to a single-stranded piece of DNA.
TRANSLATION:
<em>A ribosome receives the mRNA molecule and starts to build a chain of amino acids (a protein) that exactly matches the instructions within the mRNA.</em>
The ribosome ‘reads’ the mRNA sequence as a series of three-base chunks or codons. Each codon tells the protein-making machinery which amino acid to add next.
Making a protein
:
Protein synthesis (or gene expression) is a two-stage process. In the first stage (transcription), an mRNA molecule is produced that echoes the DNA sequence of the gene being expressed. In the second stage (translation), a chain of amino acids is formed at the ribosome, following the instructions provided by the mRNA molecule.
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.
