central dogma of molecular biology

DNA is found in chromosomes. In eukaryotic cells, chromosomes always remain in the nucleus, but proteins are made at ribosomes in the cytoplasm.

This nucleic acid is RNA, or ribonucleic acid. RNA is a small molecule that can squeeze through pores in the nuclear membrane.

It carries the information from DNA in the nucleus to a ribosome in the cytoplasm and then helps assemble the protein. In short:

Chargaff found that concentrations of the four bases differed from one species to another. However, within each species, the concentration of adenine was always about the same as the concentration of thymine. The same was true of the concentrations of g

copies the genetic instructions from DNA in the nucleus, and carries them to the cytoplasm.

helps form ribosomes, where proteins are assembled.

brings amino acids to ribosomes, where they are joined together to form proteins.

Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter.

The process in which cells make proteins is called protein synthesis. It actually consists of two processes: transcrip- tion and translation.

Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.
