To solve this problem, we need to determine the fate of a piece of DNA carrying only a gene of interest when transferred into an alien organism. Let's analyze each option:$\newline \bullet$A. The piece of DNA would be able to multiply itself independently in the progeny cells of the organism.$\newline$ - This is unlikely because, for independent replication, the DNA would need an origin of replication compatible with the host's cellular machinery.$\newline \bullet$B. It may get integrated into the genome of the recipient.$\newline$ - This is possible if the DNA integrates into the host genome through recombination or other mechanisms.$\newline \bullet$C. It may multiply and be inherited along with the host DNA.$\newline$ - This can occur if the DNA integrates into the host genome or if it has a compatible origin of replication.$\newline \bullet$D. The alien piece of DNA is not an integral part of the chromosome.$\newline$ - This is true if the DNA does not integrate into the host genome.$\newline \bullet$E. It shows the ability to replicate.$\newline$ - This is possible if the DNA has a compatible origin of replication.$\newline$Now, let's determine the correct combination of options:$\newline$Option 1: B and C only - This is correct because the DNA may integrate into the genome (B) and be inherited along with the host DNA (C).$\newline$Option 2: A and E only - This is incorrect because independent replication (A) is unlikely without a compatible origin of replication.$\newline$Option 3: A and B only - This is incorrect because independent replication (A) is unlikely.$\newline$Option 4: D and E only - This is incorrect because D and E do not necessarily occur together.$\newline$Therefore, the correct answer is Option 1: B and C only.
