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.
Question
Transcribed Image Text:### Question:
If Avery, MacLeod, and McCarty had determined that the transforming molecule was RNA, what experimental results would have been observed?
### Answer Choices:
1. ○ S cell DNA extracts treated with RNase would lyse the nucleus
2. ○ S cell DNA extracts treated with RNase would not transform the R cells
3. ○ S cell DNA extracts treated with DNase would not transform the R cells
4. ○ S cell DNA extracts would not transform the R cells at all
5. ○ None of the answers are correct
This question pertains to the famous experiment by Avery, MacLeod, and McCarty, which identified DNA as the transforming material that could transfer genetic information from one cell to another. The different choices represent potential experimental outcomes if RNA rather than DNA had been determined to be the transforming molecule.
Here’s an explanation of what each choice implies:
1. **S cell DNA extracts treated with RNase would lyse the nucleus** - This suggests RNase would somehow affect the nucleus.
2. **S cell DNA extracts treated with RNase would not transform the R cells** - This suggests RNase treatment would hinder transformation if RNA was the transforming molecule.
3. **S cell DNA extracts treated with DNase would not transform the R cells** - This suggests DNase would prevent transformation if DNA was the transforming molecule.
4. **S cell DNA extracts would not transform the R cells at all** - This implies no transformation takes place under any conditions.
5. **None of the answers are correct** - There could be another explanation or unlisted outcome.
The correct experimental outcome would be Choice 2: S cell DNA extracts treated with RNase would not transform the R cells, implying RNA is the transforming material.
