Write short notes on the following:
(i) DNA Palindrome
(ii) Carrying capacity
Show Hint
Understanding DNA palindromes is crucial for DNA analysis and manipulation, while carrying capacity helps in understanding population dynamics.

Solution and Explanation
(i) DNA Palindrome:
A DNA palindrome is a sequence of base pairs in double-stranded DNA where the sequence of bases reads the same forward and backward on complementary strands. Palindromes are often recognized by restriction enzymes, which cleave DNA at these sites. Example:
5'–GAATTC–3' (on one strand)
3'–CTTAAG–5' (on the complementary strand)
(ii) Carrying Capacity:
Carrying capacity refers to the maximum population size that an environment can sustainably support, given the available resources (food, space, etc.). It is determined by factors such as food availability, habitat space, and the presence of predators. Populations that exceed the carrying capacity experience a population crash due to resource depletion.
Final Answer: DNA palindromes are sequences that read the same in both directions on complementary strands, while carrying capacity refers to the maximum population size an environment can support.
Final Answer: DNA palindromes are sequences that read the same in both directions on complementary strands, while carrying capacity refers to the maximum population size an environment can support.

Top Questions on Biotechnology
The vector, shown in the figure, has promoter and RBS sequences in the 300 bp region between the restriction sites for enzymes X and Y. There are no other sites for X and Y in the vector. The promoter is directed towards the Y site. The insert containing only an ORF provides 3 fragments after digestion with both enzymes X and Y. The ORF is cloned in the correct orientation in the vector using the single restriction enzyme Y. The size of the largest fragment of the recombinant plasmid expressing the ORF upon digestion with enzyme X is ........... bp. (answer in integer)
