Definition: "Copying of information from DNA to RNA which exit nucleus is known as transcription"
Explanation: Transcription is a vital process for living organisms, because it is a staring point for protein synthesis. It occurs inside the nucleus and is carried out by RNA polymerase enzyme. In eukaryotes RNA pol is of three types: these are RNA Pol 1, RNA Pol 2, and RNA Pol 3. In prokaryotes it is of only one type.
Steps in transcription: Transcription consists of three main steps
1. Initiation: In this step RNA pol attach to DNA template at 5 prime end in the promoter region to start the formation of complementary strand of RNA. In prokaryotes there is a region called

2. Strand elongation: </span><span>Once transcription is initiated, the DNA double helix unwinds and RNA polymerase reads the template strand, adding nucleotides to the 3′ end of the growing chain.

3. Transcription Termination:
Terminator sequences are found close to the ends of non-coding sequences. Before termination polyadenylation occurs. <span>

Answer:
The act of carefully watching or examining a person or object when something is happening is known as an observation. An act of deriving rational conclusion from known facts or circumstances is called inference. ... On the other hand, the inference is an explanation or assumption of what one has perceived or seen.

Answer:
answer; if u adjust the diagram on the chart it should be a little bit narrow and small but exact the diagram consist different altitudes and scopes. use
Explanation:
why well because think about it your question is what happens when the diagram on the microscope adjusts to easily.
