DNA encodes the cell's genetic instructions for making proteins. The process of making proteins from DNA is divided into two sta
ges called transcription and translation. Transcription is further divided into three steps called initiation, elongation, and termination. Classify the statements about transcription according to the step in which each occurs.
Transcription is the synthesis of RNA from the DNA. It is further divided into three steps:
Initiation: In this step at first, there is binding of RNA polymerase to the group of transcription factors, it binds at the promoter. It is followed by unwinding of DNA double helix, and then the synthesis of RNA starts.
Elongation: The RNA polymerase extends across the DNA template, it adds the base pairs in 5' to 3' direction. In the same step proofreading of RNA is done to eliminate the errors in synthesis.
Termination: In this step RNA polymerase detaches, at certain stop signals, adding of further base pairs is also terminated by RNA polymerase. The newly synthesized transcript of RNA is released.
Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages.
Temperate phages don't immediately kill their hosts.
Explanation:
There exist phages that have shown the capability to alternate lytic and lysogenic life cycles, where don't kill the host cell. This feature allows a phage to reproduce without killing the host cells, thereby having higher probabilities of replicating its genetic material
The appropriate answer is the dew point is lowest in the afternoon. Dew point refers to the stage at which water droplets from via the process of condensation. It is the temperature to which the air must be cooled to allow this process of condensation. Humidity refers to the amount of water vapor contained in the surrounding air.
