Plasmids differ from transposons in that plasmids
a. become inserted into chromosomes.
b. are self-replicated outside the chromosome.
c. move from chromosome to chromosome.
d. carry genes for antibiotic resistance.
e. none of the above

검증된 단계별 안내

Understand the definitions of plasmids and transposons: Plasmids are small, circular DNA molecules that replicate independently of the bacterial chromosome, while transposons are DNA sequences that can move from one location to another within the genome.

Analyze option (a): 'become inserted into chromosomes.' Transposons typically insert themselves into chromosomes, but plasmids usually exist independently, so this is more characteristic of transposons.

Analyze option (b): 'are self-replicated outside the chromosome.' Plasmids have their own origin of replication and can replicate independently in the cytoplasm, which is a key difference from transposons.

Analyze option (c): 'move from chromosome to chromosome.' This describes transposons, which can jump between chromosomal locations, not plasmids.

Analyze option (d): 'carry genes for antibiotic resistance.' Both plasmids and transposons can carry antibiotic resistance genes, so this is not a distinguishing feature.

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

Plasmids

Plasmids are small, circular DNA molecules found in bacteria that replicate independently of the chromosomal DNA. They often carry genes that provide advantages, such as antibiotic resistance, and can be transferred between bacteria through processes like conjugation.

Transposons

Transposons, or 'jumping genes,' are DNA sequences that can move from one location to another within a genome, including between chromosomes or plasmids. Unlike plasmids, they do not replicate independently but integrate into the host DNA.

Differences between Plasmids and Transposons

The key difference is that plasmids replicate autonomously outside the chromosome, while transposons move within the genome but do not self-replicate independently. Both can carry genes like those for antibiotic resistance, but their mobility and replication mechanisms differ.
