Term
RNA
Definition
RNA is ribonucleic acid. RNA is protein synthesis and converts amino acids into proteins.
Term
messenger RNA
Definition
Messenger RNA is transcribed in the nucleus and enters into the cytoplasm. It also contains instructions for assembling amino acids into proteins. It also carries DNA to other parts of the cell.
Term
ribosomal RNA
Definition
Ribosomal RNA combines with proteins to form ribosomes.
Term
transfer RNA
Definition
After proteins are built, it transfers each amino acid to the ribosome.
Term
transcription
Definition
Transcription is the synthesis of a RNA molecule from a DNA template.
Term
RNA polymerase
Definition
RNA polymerase are enzymes that link together the growing chain of RNA nucleotides during transcription using a DNA strand as a template.
Term
promoter
Definition
Promoter is a specific area on the gene where RNA polymerase can bind and begin transcription.
Term
intron
Definition
Intron is the cut out sequence of the DNA that is not involved in coding for a protein.
Term
exon
Definition
Exons are the sequences spliced back together to form the final mRNA.
