- Which 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.WRITE ABOUT A THEME: INFORMATION In a short essay(100–150 words), explain how specification of the adultnervous system by the genome is incomplete.Part 1. Transduction is a form of horizontal gene transfer that involves viral infections. random mutation. physical contact between cells. acquisition of DNA from the environment. Part 2: Transformation is a mechanism of horizontal gene transfer that requires a virus to infect a cell. requires physical contact. transfers genetic information from parents to offspring. requires DNA to be present in the environment.
- cells that can be found in crocodile skinWhich 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.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 more copies of the viral genome. d. mRNA works outside of the host cell to produce enzymes and proteins.
- Choose the combination of answers that most accurately completes the statement. Transfer RNA is the molecule that a. contributes to the structure of ribosomes b. adapts the genetic code to protein structure c. transfers the DNA code to mRNA d. provides the master code for amino acidsWhich statement best describes the manner in which the genetic information is used inside cells? DNA is converted to RNA, which is then converted to protein. DNA acts as a messenger. It binds to a ribosome and provides instructions for making protein. Ribosomes make proteins by randomly linking amino acids together. Sections of DNA are copied into RNA molecules which serve as the instructions for making proteins.Many viruses can stop the host cell from translating host mRNAs. Compare the way coronaviruses do this to how influenza viruses do this.
