Answer #1

Ans : True.

Explanatin :

Lambda phages infect bacterial cells through two different pathways : Lytic cycle and Lysogenic cycle.

In lytic cycle, the phage DNA utilizes bacterial RNA polymerases to replicate and make multiple copies of its genome which enables the production of numerous new phages that causes the cell to rupture, releasing the newly assembled phages out of the bacterial cell.

In lysogenic cycle, the replication and protein formation mechanism is inhibited by repressor gene C1 present on the phage genome. Reprossor genes produce C1 protein which binds with and inactivates lytic cycle genes involved in phage DNA replication and translation. Consequently, the phage DNA remains in the bacterial genome to form a prophage and is carried through several generations of the bacterial cell until it enters back the lttic cyle later on.

Imagine that you are studying a repressor protein. Your experiments show that the repressor binds to a promoter UNLESS maltose (a sugar) is present. Further, you show that the repressor binds directly to maltose and that maltose binding causes the repressor to leave the promoter. In this case, maltose is acting as: An inducer. An activator. An operator. A co-repressor

The Central Dogma Explain how our genes control our traits with a specific example. Your explanation should contain the following words: transcription, translation, gene, mRNA, and protein. You should include the name of a specific gene and a specific protein, and try explain how the role of that particular protein relates to the trait (example: the pigment melanin is a protein that results in brown eyes, skin and hair). To demonstrate that you have understood how transcription and translation works,...
