Match the following

• Holds the genetic information of all living things.

• mRNA

• Major constituent of ribosomes.

• rRNA

• Carry protein information from the DNA in a cell's nucleus to the cell's cytoplasm.

• tRNA

• Brings the amino acids and places them in the correct potsition to create the desired protein

• DNA

When DNA splits into single strands to act as a template for a new strand of complementary DNA, it is called ​ (a)   . ​ The process by which ​ DNA is copied to ​ (b)   , which carries the information needed for protein synthesis is called ​ (c)   . The mRNA formed in transcription is transported out of the ​ (d)   , into the cytoplasm, to the ribosome (the cell's protein synthesis factory). With the help of tRNA the protein chain is assembled in a process known as ​ (e)   .
