Introduction:
The recombinant DNA technology involves isolation of genetic materials (DNA) from donor organisms (human, plant, or microorganism) and inserts them into recipient organisms after genetic manipulation. The main tools involved in the techniques are

- Which statement is true of viral replication? a. In the process of apoptosis, the cell survives. b. During attachment, the virus attaches at specific sites on the cell surface. c. The viral capsid helps the host cell produce mow copies of the viral genome. d. mRNA works outside of the host cell to produce enzymes and proteins.arrow_forwardYou have developed a drug to prevent a virus from replicating. Explain how your drug works to stop the virus from replicating. Be detailed in your answerarrow_forwardWhich statement is true of reverse transcriptase? a. It is a nucleic acid. b. It infects cells. c. It transcribes RNA to make DNA. d. It is a lipid.arrow_forward
- evaluate the safeguards used in research using genetic engineering.arrow_forward(short answer) Imagine you’ve been offered a deal from a genomics company. You can get a free genome sequence – an analysis of all of your DNA that includes a report of your ancestry, traits and a medical profile. The medical profile tells you about diseases for which you have a low risk of getting, and also those you have a high risk of getting. Are you interested? Why or why not?arrow_forwardWhich is true of the lagging strand in DNA synthesis? a. It is built elongating towards the replication fork b. It is composed entirely of RNA c. It is built in the 3’ to 5’ direction d. It elongates in a series of segments, rather than continuouslyarrow_forward
- How is the Zika virus spread? A. Through person-to-person contact B. Through mosquito bites C. Through the release of the virus into the air by plants D. Through dog bitesarrow_forwardWrite short answers. i. RNA not exists in double stranded from as DNA. Why?arrow_forwardTo speculate means to ask ________________________.arrow_forward
- What do genetic engineers use to create the “sticky ends” needed to splice two fragments of DNA together? a.) an amino acid sequence b.) DNA ligase c.) restriction enzymes d.) mRNAarrow_forwardWhich helps prevent errors in DNA replication? A) Complementary base pairing reduce errors B) DNA ligase checks the DNA for errors C) DNA is located in the ribosomes D) Any base can pair with any other basearrow_forwardWhich is true of DNA viruses? a. They use the host cell’s machinery to produce new copies of their genome. b. They all have envelopes. c. They are the only kind of viruses that can cause cancer. d. They are not important plant pathogens.arrow_forward
