1. Which of the following is a monomer of proteins?
A. Nucleotide
B. Amino acid
C. Fatty acid
D. Glucose
Amino acids are the building blocks (monomers) of proteins.
2. The primary structure of a protein is determined by:
A. Hydrogen bonds
B. Ionic interactions
C. Alpha helices
D. The sequence of amino acids
Primary structure refers to the linear sequence of amino acids in the
polypeptide chain.
3. Which organelle is responsible for ATP production?
A. Nucleus
B. Ribosome
C. Mitochondrion
D. Golgi apparatus
Mitochondria are the site of cellular respiration and ATP generation.
,4. DNA replication is:
A. Semiconservative
B. Conservative
C. Dispersive
D. Non-replicative
Each new DNA molecule consists of one old strand and one newly
synthesized strand.
5. What type of bond links the nucleotides in DNA?
A. Hydrogen bond
B. Phosphodiester bond
C. Peptide bond
D. Ionic bond
Phosphodiester bonds form between the phosphate group of one nucleotide
and the sugar of the next.
6. During transcription, RNA polymerase reads:
A. mRNA
B. DNA template strand
C. DNA coding strand
D. tRNA
RNA polymerase synthesizes RNA by reading the DNA template strand.
7. Which RNA molecule carries amino acids to the ribosome?
A. mRNA
B. tRNA
C. rRNA
, D. snRNA
tRNA carries specific amino acids and matches them to the codons in mRNA
during translation.
8. The endosymbiotic theory explains the origin of:
A. Ribosomes
B. Mitochondria and chloroplasts
C. Nucleus
D. Golgi apparatus
This theory suggests mitochondria and chloroplasts were once free-living
prokaryotes.
9. An enzyme lowers:
A. ΔG of the reaction
B. Product concentration
C. Activation energy
D. Substrate concentration
Enzymes speed up reactions by lowering the activation energy.
10.Which macromolecule contains phosphorus?
A. Carbohydrates
B. Lipids
C. Proteins
D. Nucleic acids
Nucleic acids have phosphate groups in their sugar-phosphate backbone.
