DNA Transcription

Date : 15 Apr 2008

By way of transcription, cells are exercised in use for carrying out the instructions that are enclosed in genes. Process of DNA transcription involves the procedure of transcribing of genetic information from DNA to RNA. DNA is transcribed by means of enzyme known as RNA polymerase which further synthesizes an RNA copy of the information in DNA.

RNA transcription process is quite similar to the process of DNA replication. DNA replication is the process of copying the double-standard DNA molecule. Each DNA strand carries the same genetic information. And so, for this reason, both parent and child cell have a complete copy of genetic information. However, rather than thymine, RNA encompasses a different base called uracil.   

DNA is found in the body of every human being. To be exact: in each living cell of the body, such as: hair, blood, skin and many other parts of the body. DNA Transcription has very important place in the fraternity of law. It helps in identifying a person. Nearly every organism, whether it is a human being, bacteria, rosebush or ant contain some form of nucleic acid that provides the genetic information. Basically, there are two types of nucleic acids, Deoxyribonucleic acid (short for DNA) and Ribonucleic acid (short for RNA) that codes for all the information that further helps in determining the nature of the organism's cells.

DNA bears the code for the synthesis of all the proteins which regulates and maintains the functions of the cell. The DNA transcription process involves the synthesis of a messenger RNA (mRNA) from the DNA. This mRNA is complementary to the DNA which has to be decoded and takes-up the information which is essential for the ribosome to produce proteins. Thus, ribosomes that include rRNA formulate proteins from the messages that are encoded in mRNA.

Three types of RNA are transcribed from DNA:

• Transfer RNA (tRNA).
• Ribosomal RNA (rRNA).
• Messenger RNA (mRNA).
