2. Ribosomes, Transcription, Translation | Learn Science at Scitable - Nature
In prokaryotic cells, transcription (DNA to mRNA) and translation (mRNA to protein) are so closely linked that translation usually begins before transcription ...
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.
3. Transcription: an overview of DNA transcription (article) - Khan Academy
In transcription, the DNA sequence of a gene is transcribed (copied out) to make an RNA molecule. Key points: Transcription is the first step in gene expression ...

4. DNA Transcription | Learn Science at Scitable - Nature
In eukaryotes, genes transcribed into RNA transcripts by the enzyme RNA polymerase II are controlled by a core promoter. A core promoter consists of a ...
The process of making a ribonucleic acid (RNA) copy of a DNA (deoxyribonucleic acid) molecule, called transcription, is necessary for all forms of life. The mechanisms involved in transcription are similar among organisms but can differ in detail, especially between prokaryotes and eukaryotes. There are several types of RNA molecules, and all are made through transcription. Of particular importance is messenger RNA, which is the form of RNA that will ultimately be translated into protein.
5. How do genes direct the production of proteins?: MedlinePlus Genetics
Mar 26, 2021 · During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA (ribonucleic acid) in the ...
Genes make proteins through two steps: transcription and translation. This process is known as gene expression. Learn more about how this process works.
6. 15.4: Protein Synthesis - Biology LibreTexts
May 13, 2020 · Transcription is the first part of the central dogma of molecular biology: DNA → RNA. It is the transfer of genetic instructions in DNA to mRNA ...
Your DNA, or deoxyribonucleic acid, contains the genes that determine who you are. How can this organic molecule control your characteristics? DNA contains instructions for all the proteins your body …
7. Part Three: Gene Expression and Protein Synthesis

8. Prokaryotic and Eukaryotic Gene Regulation | Biology for Non-Majors I
In eukaryotic cells, the DNA is contained inside the cell's nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of ...
To understand how gene expression is regulated, we must first understand how a gene codes for a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different manners.
9. 5. Gene Expression: Transcription
The coding region is the part of the gene that is used as template to produce RNA molecules in a process called transcription. Some RNA molecules perform ...
