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>

NeTakaya

Answer:

Many people with blood cancers, such as leukemia and lymphoma, sickle cell anemia, and other life-threatening diseases, rely on bone marrow or cord blood transplants to survive.

Healthy bone marrow and blood cells are needed in order to live. When disease affects bone marrow so that it can no longer function effectively, a marrow or cord blood transplant could be the best treatment option; for some patients it is the only potential cure.
