▉ The flow of information are following.
First the DNA play most important role and act as a command center.DNA is the center where instructions are transmit to RNA and than RNA synthesize protein for gene expression.
- Replication.
In replication double stranded DNA is denature and convert to single stranded.
- Transcription.
Flow of information from DNA to RNA is called transcription.
- Translation.
RNA obey the instruction of DNA and synthesize protein.
▉ Different between DNA and RNA.
- DNA
- The nucleic acid of DNA is composed of nucleotide.
- DNA is form of double stranded.
- The derivation of DNA is deoxyribose sugar
- Nucleotide of DNA are thymine cytocine,guanine and adenine.
- RNA.
- Single strandded type.
- In RNA the nucleotide of thymine is replaced by Uracil.
▉ RNA Types and their Roles are following:
- pre-mRNA
This type of RNA is newely synthesize from first one and not changeable form.
- mRNA.
Editable form new version carry the code of nucleic acid.
- tRNA.
Act like translator and based on its anticodon to mRNA.
- RNAi.
Interference and behave regulatory molecule.
- rRNA.
It function to make above 60% of ribosomes.
- Ribozyme.
Is a enzyme of RNA molecules.
- Genetic Code.
In gene one strand act as template strand.These strand are opposite start from 5 to 3 template.Codon of DNA compose 3 nucleotide In which 64 combination of codon are present.This code is same for all organisms in world.
