DNA, RNA, and Proteins (14.1, 14.2)

3 Types of RNA

• Messenger RNA, Transfer RNA, and Ribosomal RNA
• Transcription, Monomers, and Nucleus

mRNA

• Transfer RNA
• messenger RNA
• Ribosomal RNA

tRNA

• Transfer RNA
• Messenger RNA
• Ribosomal RNA

rRNA

• Messenger RNA
• Transfer RNA
• Ribosomal RNA

mRNA can be found in___________

• nucleus, cytoplasm, or ribosomes
• amino acids

tRNA can be found in 

• cytoplasm or ribosomes
• nucleus

mRNA 

• takes information from a gene to a ribosome so a protein can be made

• transfers an amino acid from the cytoplasm to the ribosome

tRNA

• Brings an amino acid from the cytoplasm to the ribosomes

• copies the gene in the nucleus and carries that information to the ribosome in the cytoplasm

rRNA

• contains codons

• forms ribosomes; helps attach mRNA to ribosomes

Transcription is when

• mRNA molecule is made from DNA
• making of proteins from the mRNA
