MMSC490 Questions and Correct
Answers/ Latest Update / Already Graded
What are genes?
Ans: Segments of DNA that encode proteins or RNA.
What is transcription?
Ans: The process where the nucleotide gene sequence is copied
into RNA.
What is translation?
Ans: The process where the nucleotide sequence of RNA is
used to specify the order of amino acids in a protein.
What are the main components of present-day biological membranes?
Ans: They are composed of phospholipids, which have
hydrophobic hydrocarbon chains and hydrophilic head groups.
What is the primary source of metabolic energy in cells?
Ans: ATP generated by glycolysis.

How does photosynthesis contribute to energy metabolism?
Ans: It harnesses energy from sunlight.
What is oxidative metabolism?
Ans: A more efficient energy-generating process than
glycolysis, producing approximately 36 to 38 ATP molecules.
What are the two main types of prokaryotes?
Ans: Archaebacteria and Bacteria.
What is a typical characteristic of prokaryotic cells?
Ans: They are small, ranging from 1-10 micrometers in
diameter.
What is the significance of cyanobacteria?
Ans: They are the largest and most complex prokaryotes and
were involved in the evolution of photosynthesis.

Ans: Eukaryotic cells are larger, more complex, and contain a
nucleus and organelles.
What is the function of the nucleus in eukaryotic cells?
Ans: It is the site of DNA replication and RNA synthesis.
What organelles are involved in photosynthesis in plant cells?
Ans: Chloroplasts.
What is the role of mitochondria in animal cells?
Ans: They are involved in oxidative metabolism.
What is the function of lysosomes and peroxisomes?
Ans: They are involved in the digestion of macromolecules.
What is the role of the endoplasmic reticulum?
Ans: It is involved in the processing and transport of proteins
and lipid synthesis.
What is the function of the Golgi apparatus?
