Explanation:

examples

It gives us an opportunity to focus on specialization.

Selective breeding can be used to refine a species.

The desirable traits for humans may not be reflective of species’ needs.

It helps to provide a food chain with better sustainability.

Copying of the information in dna into rna, which can exit the nucleus is called
Oksi-84 [34.3K]
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 <span>Pribnow box, with the </span>consensus sequence<span> TATAAT present about 10 base pair away from site that serves as a transcription initiation. In eukaryotes the promoter region is more complex it contain activator and enhancer.

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