Question

How are protiens made with DNA, explain the simple and I need this asap.

Answer 1

Answer:

Using protein synthesis with two main processes :

• Transcription
• Translation

Explanation:

All organisms make proteins in essentially the same way.

process of making protein (Gene Expression) has two main stages: transcription and translation.

TRANSCRIPTION:

• Structures in the cell identify 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).
• 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:

• 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.
• 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.
