Part 1:
1.
What is the role of mRNA? Where does it come from? mRNA has the message that codes aminoacids and it comes from DNA
2.
How are ribosomes key in the translation process?
Ribosomes are key in the process because it is the place where the amino acids match the mRNA.
3.
Is the analogy between recording music and transcription and translation accurate? Explain your answer.
Yes, when you play music you are playing note by note until you make music; when you trasnsfer the music to the computer then it is changed to an electronic record of it.

4.
How many nucleotides are found in the mRNA sequence within the kit? 7
5.
What is the function of the tRNA? How many tRNA are found within the kit? 7
6.
How many amino acids are coded by the mRNA sequence kit? 7
7.
Based on model 1, what are the functions of a codon and anticodon?
The codon is the triplet code in the mRNa and anticodon is the tRNA that brings the corresponding amino acid based on the pairing rules (A-U and C-G).
8.
What can you infer about the numbers of mRNA, tRNA and amino acids you found in your kit?
The same number of each one: you need 1 codon per each anticodon and each amino acid.
9.
Why is it so important to learn about DNA’s role in protein synthesis?
Proteins are used for almost all cell functions. Learning about proteins are important to understand how muscles and the heart work, about diseases and possible treatment or how the ingestion of certain foods could affect the function of these proteins, for example.
