Match the following genetic elements with their functions.
Genetic elements Functions A. neoR 1. Facilitates inducible expression of genes in eukaryotes B. SV40 2. Facilitates constitutive expression of genes in eukaryotes C. LTR 3. Allows amplification of gene D. dhfr 4. Provides way of selecting eukaryotic cells, which have received foreign DNA

- A → 4, B → 2, C → 1, D → 3
- A → 2, B → 4, C → 1, D → 3
- A → 1, B → 4, C → 2, D → 3
- A → 4, B → 2, C → 3, D → 1
Correct Option: A
neoR stands for the eukaryotic gene expression marker, SV40 facilitate gene expression in eukaryotes, LTR induces new gene expression and dhfr is a gene amplification factor.
