Which of the following is used to select genes of interest from a genomic library?
1 Restriction enzymes
2 Cloning vectors
3 Gene targets
4 DNA probes
Explanation:
DNA probes are short, single- stranded pieces of DNA that are used to detect the presence of specific sequences of DNA or RNA in a sample. They are typically labeled with a zfluorescent or radioactive marker, making it possible to visualize and identify the target DNA or RNA. -Cloning vectors- Cloning vector is a small DNA molecule capable of self replication inside the host cell.

c-DNA is formed from m-RNA by which enzyme:
1 restriction endonuclease
2 reverse transcriptase
3 DNA polymerase
4 RNA polymerase
Explanation:
c-DNA is formed from m-RNA by enzyme. reverse transcriptase - Restriction endonuclease - Restriction endonuclease enzyme recognize short, specific sequence within DNA, cut the DNA. These enzyme are vital in the process of protein synthesis.
