Living beings maintain continuity of life by:
- Adaptation
DNA – replication and its transfer in next generation
- RNA synthesis
- None of the above
The Correct Option is B
Solution and Explanation
Living beings maintain continuity of life primarily through DNA replication and its transfer to the next generation. This process ensures that genetic information is passed onto offspring, allowing for the preservation of species and genetic traits.
So, the correct option is (B): DNA – replication and its transfer in next generation

Questions Asked in NEET exam
- Given below are two statements:
Statement I: The DNA fragments extracted from gel electrophoresis can be used in the construction of recombinant DNA.
Statement II: Smaller size DNA fragments are observed near the anode while larger fragments are found near the wells in an agarose gel.- NEET (UG) - 2025

Given below are two statements:
Statement I: Transfer RNAs and ribosomal RNA do not interact with mRNA.
Statement II: RNA interference (RNAi) takes place in all eukaryotic organisms as a method of cellular defence.
In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025
- RNA interference
- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

- Two gases A and B are filled at the same pressure in separate cylinders with movable pistons of radii \(r_A\) and \(r_B\) respectively. On supplying an equal amount of heat to both the cylinders, their pressures remain constant and their pistons are displaced by 16 cm and 9 cm respectively. If the change in their internal energies is the same, then the ratio \(r_A / r_B\) is:

Reproduction
The term reproduction is a biological process that means to reproduce. It is a process by which an organism reproduces an offspring that is biologically similar or identical to its parents. Reproduction accredits and ensures the continuity of species, generation after generation, and is the main character of life on earth.
Types of Reproduction:
There are two types of reproduction such as:
Asexual Reproduction:
It is the production an offspring by a single parent beyond the formation and fusion of gametes. The young one obtains all its genes from one parent, so are identical.
Sexual Reproduction:
Sexual reproduction is mostly biparental, includes the formation of meiosis gamete usually fertilization also, instigates genetic variation in the offspring, and plays a role in the evolution of species, found in higher plants and animals.
