Chapter 8, Problem 2
Transfer of DNA from a donor to a recipient as naked DNA in solution.
a. Conjugation
b. Transcription
c. Transduction
d. Transformation
e. Translation
Verified step by step guidance1
Read the problem carefully to understand that it asks for matching a term to the definition: 'Transfer of DNA from a donor to a recipient as naked DNA in solution.'
Recall the definitions of the given terms: conjugation, transcription, transduction, transformation, and translation.
Identify that 'conjugation' involves direct cell-to-cell contact for DNA transfer, so it does not match the definition.
Recognize that 'transcription' and 'translation' are processes related to gene expression, not DNA transfer between cells.
Understand that 'transformation' is the process where bacteria take up naked DNA from their environment, matching the definition given.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Transformation
Transformation is the process by which bacteria take up free, naked DNA fragments from their environment and incorporate them into their own genome. This horizontal gene transfer method allows genetic variation without direct cell-to-cell contact.

Bacterial Transformation
Conjugation
Conjugation involves the direct transfer of DNA from a donor to a recipient bacterial cell through physical contact, usually via a pilus. It is a common mechanism for spreading plasmids and antibiotic resistance genes.

04:21Introduction to Conjugation
Transduction
Transduction is the transfer of bacterial DNA from one cell to another mediated by bacteriophages (viruses that infect bacteria). It occurs when phages accidentally package host DNA and inject it into a new host.
