How are DNA and mRNA alike?

They are both made of nucleic acid
How are DNA and mRNA different? (How many strands, Nitrogen Bases, Location)

DNA: 2 Strands, ATGC, Nucleus

mRNA: 1 Strand, AUGC, Ribosome+Nucleus (It moves around, while DNA can't)
How many strand of mRNA are transcribed from the two "unzipped" strands of DNA?

1
If the following were part of a DNA chain, what mRNA bases would pair with it to transcribe it?

A-T-G G-C-A T-A-C

U-A-C C-G-U A-U-G
If DNA is described as a double helix, how should mRNA be described?

Uni-Helix/ Single- Helix
Which nitrogen base replaces Thymine in tRNA?

Uracil
Name and describe the two types of RNA involved in protein synthesis?
- mRNA: Messenger
- tRNA: Transferer
What is located at each end of tRNA molecule?

Amino-Acid and Anti-Codon
Where must an mRNA attach before protein production can begin?

Ribosome
How many nitrogen bases are needed to specify and mRNA codon?

3
What is the relationship between amino acids and proteins?

The amino acids create the proteins
What is the protein synthesis flow chart?\
In order?
- 1. (First Part)Transcription
- 2. (Take place in the) Nucleus
- 3. (Where DNA is decoded into)mRNA
- 4. (Leaves through the) Nuclear Pore
- 5. (Goes to a) Ribosome
- 6. (The 2nd part of Protein Synthesis) Translation
- 7. (Where) tRNA anticodons bond with...
- 8. mRNA codon
- 9. (Then) Ribosome
- 10. (Create) Peptide bonds
- 11. (Between) Amino Acids
- 12. (Creating a) Protein!!
