The disease caused by the fungus Candida albicans is called: MCQ with Answer and Explanation

Explanation:
A gene is a specific sequence of nucleotides in DNA that serves as the fundamental unit of heredity, typically coding for a specific protein or RNA molecule. Alleles are different versions or alternative forms of the same gene that occupy the same locus on homologous chromosomes and determine variations in a trait. The genotype is the genetic makeup of an organism, while the phenotype is the observable physical or biochemical characteristics. Thus, statements 1 and 2 are correct.

Explanation:
Bacteria are unicellular prokaryotic organisms, characterized by the absence of a true, membrane-bound nucleus and other membrane-bound organelles. Fungi are eukaryotic organisms, possessing a true nucleus and membrane-bound organelles, and can be unicellular (yeasts) or multicellular (molds, mushrooms). Viruses are acellular, non-cellular entities; they consist of genetic material (DNA or RNA) enclosed in a protein coat (capsid) and lack any cellular structure or independent metabolic machinery. Thus, statements 1 and 2 are correct.

Explanation:
Restriction endonucleases cut DNA at specific palindrome sequences, generating sticky or blunt ends, which can be ligated to vector DNA. This is the basis of genetic engineering. R explains A.
