Transcription and Translation

Transcription ( -> )
1. A section of unravels due to an enzyme called .
2. The strand connects to the complementary bases of the DNA. (A to , T to , G to , C to )
3. The leaves the nucleus.

Note: mRNA stands for RNA. There are two other types of RNA.
rRNA - RNA
tRNA - RNA

Translation ( -> amino acid chain/polypeptide)
1. A attaches to the strand of .
2. A anticodon matches with a complementary set of an codon. (A to , U to , G to , C to )
Each tRNA anticodon is attached with a specific amino acid.
3. The ribosome slides over the first codon of the mRNA chain. Translation occurs from the 5' to the 3'.
4. Then, the ribosome moves to the next codon with the complementary tRNA anticodon and adds another amino acid next to the first one. The amino acids join with a bond.

Note: A codon is a set of 3 letters. So, the tRNA "reads' the mRNA (message) 3 letters at a time. Therefore, an anticodon is also 3 letters.
Here is an example:
mRNA --- - GCC - AAA - GAC - GUC - <<< These sets of 3 are codons. This chain contains 6 codons.
tRNA --- UAC - CGG - - - CAG - AUC <<< These sets of 3 are anticodons. This chain has 6 anticodons.

Note: Since only one side of the DNA is transcribed at a time by the mRNA, use the side with the asterisks (*) after it. Also, A.A. stands fro amino acid and please abbreviate the amino acids. The image has the abbreviations. If unclear or highly pixelated, the codon chart on the last question has the abbreviations. Your answer will only be marked correct if you place spaces in between the letters and do not place a dot ofter the a.a. abbreviation.
No -> ATCGTA
Yes-> A T C G T A
No -> val. - ser.
Yes-> val - ser
