RNA goes to the ribosome where it is used as a guide to attach amino acids together. Amino acids in a chain is a protein

• This is Transcription.

• This is Translation.

What type of RNA carries the DNA message out of the nucleus to the ribosomes?

• mRNA

• tRNA

• RNA

• DNA

DNA is used as a guide to rewrite the genetic code into RNA. RNA can then leave the nucleus.

• This is Transcription.

• This is Translation.

​ (a)   : forms part of ribosomes, cell's protein factories

​ ​ (b)   : brings amino acids from cytoplasm to a ribosome to help make growing proteins.

​ (c)   : intermediate message that is translated to form a protein

• rRNA

• tRNA

• mRNA

Match the following processes with their products

• DNA

• transcription

• protein

• replication

• mRNA

• translation

A nucleic acid similar in structure and properties to DNA, but it only has a single strand of bases.
