Question
Student Name: 1. In the laboratory, DNA molecules can be cut at specific sequences using: A) UV light B) restriction nucleases C) DNA ligase D) laser tweezers 2. Plasmids are important in biotechnology because they are A) a vehicle for the insertion of recombinant DNA into bacteria. B) recognition sites on recombinant DNA strands C) surfaces for protein synthesis in eukaryotic recombinants. D) surfaces for respiratory processes in bacteria E) proviruses incorporated into the host DNA 3. The enzyme reverse transcriptase enables scientists to produce what product A) Restriction endonucleases B) cDNA molecules C) Restriction fragment length polymorphisms D) Blunt end restriction fragments E) mRNA transcripts 4. Introduction of DNA molecules into the recipient organism is termed as: a) transformation b) translation c) transduction d) transcriptionExplanation / Answer
1-option b is correct because restriction nuclease is type of restriction endonuclease which cut at specific site.
2-option a is correct because plasmid act as vector which used in genetic engineering for insertion of foreign DNA into host cell.
3-option b is correct because in reverse transcriptase cDNA formed from mRNA.
4-option c is correct because in transduction foreign DNA transfer into bacteria through virus.
