Which of the following options best depicts the flow of information when a gene
directs the synthesis of a cellular component?
A) RNA → DNA RNA →
protein
B) DNA
→ amino acid → RNA → protein
O C) protein
RNA DNA
D) DNA - TRNA → MRNA –→ protein
O E) DNA - RNA →
protein
Illustrate the central dogma of life showing:
a) codons
b) Complementary strand of the master DNA
c) DNA master template of 12 bases
Below are the steps of protein synthesis. What is the correct sequential
order? 1. MRNA is formed with codons as product of transcription. 2.
Codons are translated and polypeptide chain is transferred. 3. mRNA
moves into cytoplasm and becomes associated with ribosomes. 4. DNA in
nucleus serves as a template. 5. Anticodon - codon complementary base
pairing occurs with tRNA and MRNA. *
