Which of the following are called “jumping genes”?


a. Hfr cells
b. Transducing phages
c. Palindromic sequences
d. Transposons

검증된 단계별 안내
1
Understand the term "jumping genes" refers to DNA sequences that can move or transpose themselves to different positions within the genome of a single cell, which can cause mutations and change the cell's genetic identity.
Review each option: Hfr cells are bacterial cells with a high frequency of recombination, transducing phages are viruses that transfer bacterial DNA between cells, palindromic sequences are DNA sequences that read the same forward and backward, and transposons are DNA elements that can move within the genome.
Identify that the key characteristic of "jumping genes" is the ability to move or transpose within the genome, which matches the behavior of transposons.
Conclude that among the options, transposons are the elements known as "jumping genes" because they can change their position within the genome.
Summarize that the correct answer is the option corresponding to transposons.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Transposons

Transposons, often called 'jumping genes,' are DNA sequences that can move from one location to another within a genome. This mobility allows them to cause mutations and genetic variation. They play a significant role in genome evolution and can be found in both prokaryotic and eukaryotic organisms.

Hfr Cells

Hfr (High frequency recombination) cells are bacterial cells with the F plasmid integrated into their chromosome. They can transfer chromosomal genes to a recipient during conjugation but are not related to mobile genetic elements like transposons.

Transducing Phages

Transducing phages are bacteriophages that carry bacterial DNA from one cell to another via transduction. They facilitate horizontal gene transfer but do not move within the genome like transposons.
