Plasmids are ideal vectors for gene cloning as they
1 can be multiplied in a laboratory using enzymes
2 can be multiplied by culturing
3 are self-replicating
4 replicate freely outside the bacterial cells
Explanation:
Plasmids are ideal vectors for gene cloning as they are self replicating. Plasmid are ideal cloning vectors in gene cloning because they can multiply themselves in a bacterial cell irrespective of Replication of genome DNA. - Term plasmid used by Lederberg (1952) it is extrasomal DNA. - Plasmid are of three types. F-factor or fertility factor, R-factor, Col-factor.

Cloning is meant for
1 production of $\mathrm{HaH}$ gene is $\mathrm{E}$ coli
2 to preserve the genotype of organism
3 to replace the original gene
4 all of the above
Explanation:
Cloning is meant for to preserve the genotype of organism. Cloning involves multiplication of the same genome and thus variations are limited. Clone is a population of cell or individuals which are genetically identical with the death of an organism, a particular genotype is lost. - Cloning is the production of an organism with exactly similar genetic makeup as in the mother individual. The cloning is of two types namely i.e.- gene cloning at molecular level and cloning of organism.

Extra nuclear genes occur in
1 plastids and inherited
2 plasmid and not inherited
3 mitochondria and inherited by male
4 mitochondria and inherited by female
Explanation:
Extra nuclear genes occur in mitochondria and inherited by female. The extra nuclear genes or cytoplasm inheritance is different from normal nuclear inheritance. Very basic of this difference is the unequal contribution made by father and mother as zygote receives most of it cytoplasm from the egg and very little or no cytoplasm from the sperm. Thus, it has two distinct features (i) It is more or less material inheritance, i.e., here only the female parent contribution towards inheritance because during fertilization the mitochondria in sperm are usually discarded and the offspring inherit their mitochondria exclusively from the mother's egg. This is why mitochondrial DNA (mt DNA) is often used in genetic studies to trace maternal ancestry. (ii) Due to the participation of female, only the result of reciprocal crosses.
