14) Why are telomeres so important in eukaryotic organisms: A) Without telomeres, important DNA could be lost every time the cell divides. B) They cap the mRNA, allowing it to pass through the nuclear membrane to the cytoplasm translation. C) They provide a repetitive DNA sequence needed by primers to recognize the beginning a transcription. D) They remain relatively undamaged from environmental stress and toxins.
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.
Telomeres are the section of a chromosome that is found at the end and does not contain any genetic material.
