Transfer trna - Study guides, Class notes & Summaries

List the major steps of the "central dogma" of molecular biology. What are the products of each step? Correct Answer-Replication --> DNA Transcription --> RNA Translation --> protein Once the DNA strands unwind and separate, DNA polymerases copy the DNA. What are they copying? What characteristics of DNA necessitates the need for leading and lagging strands to copy the DNA? Correct Answer-They are copying ____. DNA is antiparallel so the mode of synthesis occurs in 2 different ...

Vertical gene transfer is the process of genes being passed down from parent to offspring Correct Answer-True When bacteria take up naked genetic material from the surrounding environment, this is called Correct Answer-transformation When one bacterium transfers a copy of its plasmid to another bacterium, this is called Correct Answer-conjugation Transformation. transduction. and conjugation are all examples of Correct Answer-horizontal gene transfer What is the name of the process o...
