How does DNA encode Protein Structure?
Transcription and translation for protein synthesis processes inside our cells.
RNA stands for Ribo-nucleic acid , a single strand molecules that is involved with DNA transcription. It is different from DNA in having a ribos-sugar, phosphate and a base attached.
The nucleotides in RNA are identical to DNA nucleotides except for Thymine which is switched for Uracile in RNA. During transcription messenger RNA (mRNA) carries out information from the DNA outside the nucleus where it gets translated into amino acids.mRNA is used to direct the sequence of amino acids during the synthesis of polypeptides by ribosomes.
Translation is when mRNA is translated into amino acids sequence in the polypeptide . Ribosomal RNA is responsible for the translation process. Each group of three nucleotides encodes for specific amino acid to be added to the growing polypeptide chain.
