In a eukaryotic cell, the DNA is enclosed in the nucleus, whereas ribosomes that make proteins are located in the cytoplasm. How does the information in DNA that specifies the amino acid sequence of a particular protein get to the cytoplasmic protein-manufacturing centers

Through mRNA

Explanation:

DNA is the genetic material of most living cells and it holds the information needed for the synthesis of functional products (proteins). This information is embedded in the nuceleotide sequence of the DNA and it needs to be expressed through the processes of transcription and translation. The process of transcription occurs in the nucleus of eukaryotes where the genetic material (DNA) is located.

Transcription involves the copying of the information contained in the DNA into a carrier molecule known as messenger RNA. The messenger RNA (mRNA) is not used for long term storage unlike the DNA, it helps convey the information in the sequence out of the nucleus into the cytoplasm, where it attaches to Ribosomes (site of protein synthesis) for translation to occur. The mRNA contains complementary nucleotide sequence of the DNA.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
