Instructions for making proteins with the correct sequence of amino acids are encoded in DNA. Figure 6.4.1 6.4. 1: Transcription and translation (Protein synthesis) in a cell. DNA is found in chromosomes. In eukaryotic cells, chromosomes always remain in the nucleus, but proteins are made at ribosomes in the cytoplasm or on the rough ...
Genes encode proteins, and the instructions for making proteins are decoded in two steps: first, a messenger RNA (mRNA) molecule is produced through the transcription of DNA, and next, the mRNA ...

Jul 18, 2020 · Protein synthesis is process in which polypeptide chains are formed from coded combinations of single amino acids inside the cell. The synthesis of new polypeptides requires a coded sequence, enzymes, and messenger, ribosomal, and transfer ribonucleic acids (RNAs). Protein synthesis takes place within the nucleus and ribosomes of a cell and is ...
The decoding of information in a cell's DNA into proteins begins with a complex interaction of nucleic acids. Learn how this step inside the nucleus leads to protein synthesis in the cytoplasm.
Like DNA, RNA is made up of nucleotide consisting of a 5-carbon sugar ribose, a phosphate group, and a nitrogenous base. However, there are three main differences between DNA and RNA: RNA uses the sugar ribose instead of deoxyribose. RNA is generally single-stranded instead of double-stranded. RNA contains uracil in place of thymine.
In the first of the two stages of making protein from DNA, a gene on the DNA molecule is transcribed into a complementary mRNA molecule. Stage 1: Initiation. A region at the beginning of the gene called a promoter—a particular sequence of nucleotides—triggers the start of transcription. Stage 2: Elongation.
