(a) Major inrormation patnways DNA DNA replication Information is transferred from DNA to an RNA molecule. Information is transferred from one DNA molecule to another. -Transcription RNA Information is transferred from RNA to a protein through a code that specifies the amino acid sequence. -Translation PROTEIN (b) Special information pathways DNA In some viruses, information is transferred from RNA to DNA ... Reverse transcription ...or to another RNA molecule. RNA RNA replication- PROTEIN Pathways of information transfer within the cell. Phage attaches to E coll and injects its chromosome. Phage E. coli Bacterial chromosome Phage chromosome Bacterial chromosome breaks down and the phage chromosome replicates. Expression of phage genes produces phage structural components, Progeny phage particdes assemble. Bacterial wall lyses, releasing progeny phages. r2 is a bacteriophage that infects E. coli.
Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
