What is the processes of mitosis and meiosis indicating where the similarities lie and in which aspects they differ. What is the primary reason for each type of cell division by indicating the roles that mitosis and meiosis play in human reproduction and development?
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.
1. What is the processes of mitosis and meiosis indicating where the similarities lie and in which aspects they differ. What is the primary reason for each type of cell division by indicating the roles that mitosis and meiosis play in human reproduction and development?
2. Explain what is meant by the term ‘linked genes’ with respect to homologous recombination. For example, if an organism is heterozygous at two genetic loci on the same chromosome, in what way does the position of these alleles with respect to each other affect how they are transmitted to gametes during meiosis?
