The central dogma of the molecular biology explains how information from DNA is translated into proteins.
There are three distinct parts of this process.
Firstly, in the nucleus the DNA copies itself with help of different proteins in the process called replication.
In the second part, the information on the DNA is passed down to messenger RNA (mRNA) in the process called transcription. In this process, with the help of proteins, the sequence of DNA is divided into triplets and transcribed into a single mRNA strand.
When the mRNA is formed it leaves the nucleus and goes to the ribosome, where the translation, which is the third part of the central dogma happens.
In this process, the triplet code on the mRNA is translated into a sequence of amino acids with the help of the transport RNA (tRNA). Each triplet on mRNA compliments a triplet on the tRNA which transports one amino acid. When the whole sequence on the mRNA is translated into a sequence of amino acids the primary structure of a protein is formed.
A. theory because it is an explanation that is supported by extensive observations, experimentation, and reasoning.
Explanation:
Evolution can best be described as a theory because it is an explanation that is widely supported by extensive observations, experimentation and reasoning.
Theories are formulated after careful observation into a particular phenomenon.
- Most theories provides a vivid explanation into an observed event or process.
- The theory of evolution is one of such theories that suggests that an organism changes in order to adapt to its environment.
- Some of the key figures who contributed to the study of evolution are J. B Lamarck, Charles Darwin, Williams Smith e.t.c
