Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the function of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome and matches them to the coded mRNA message.

Front

What does it mean for an allele to be dominant?

Back

A dominant allele is one that can mask the presence of a recessive allele in a heterozygous individual.

Front

How can two brown-eyed parents have a blue-eyed child?

Back

Both parents must carry the recessive allele for blue eyes, allowing for the possibility of a blue-eyed child.

Front

What are the main differences between plant and animal cells?

Back

Plant cells have cell walls, chloroplasts, and a large central vacuole, while animal cells do not.

Front

What is a eukaryote?

Back

Eukaryotes are organisms whose cells have a nucleus and membrane-bound organelles.

Front

What is a prokaryote?

Back

Prokaryotes are unicellular organisms that lack a nucleus and membrane-bound organelles.

Front

What is the structure of a protein like ovalbumin?

Back

Ovalbumin is a protein made up of a chain of amino acids that are folded and twisted into a specific three-dimensional shape.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis, where mRNA is translated into amino acid sequences.

Front

What is the significance of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.
