Question

1. list 5 different kinds of proteins that might be made by the ribosomes.
2. distinguish between a codon and an anticodon.

codon:

anticodon:

1. a small segment of dna has the following nitrogen base sequence:

dna = tac cct acc att

Explanation:

Question 6

Ribosomes synthesize various proteins. Enzymes (e.g., amylase) catalyze reactions. Structural proteins (e.g., collagen) support tissues. Transport proteins (e.g., hemoglobin) move substances. Hormonal proteins (e.g., insulin) regulate processes. Antibodies (part of immune system) defend against pathogens.

• Codon: A sequence of 3 nitrogen bases in mRNA. It codes for an amino acid or signals (start/stop). Found on mRNA.
• Anticodon: A sequence of 3 nitrogen bases in tRNA. It pairs with a codon (complementary) to bring the correct amino acid. Found on tRNA.

Step1: Recall DNA to mRNA base pairing (A - U, T - A, C - G, G - C)

DNA sequence: TAC CCT ACC ATT

Step2: Transcribe each codon

• TAC → AUG (T→A, A→U, C→G)
• CCT → GGA (C→G, C→G, T→A)
• ACC → UGG (A→U, C→G, C→G)
• ATT → UAA (A→U, T→A, T→A)

Answer:

1. Enzymes (e.g., Amylase)
2. Structural Proteins (e.g., Collagen)
3. Transport Proteins (e.g., Hemoglobin)
4. Hormonal Proteins (e.g., Insulin)
5. Antibodies
