What is the basic unit of life?
Organism
Cell
Molecule
Atom
Describe the function of the cell membrane.
The cell membrane regulates the movement of substances in and out of the cell.
The cell membrane stores genetic information.
The cell membrane provides energy for cellular processes.
The cell membrane is responsible for protein synthesis.
What organelle is known as the powerhouse of the cell?
Mitochondria
Chloroplast
Nucleus
Ribosome
Explain the role of DNA in heredity.
DNA is only responsible for physical traits.
DNA plays a crucial role in heredity by storing and transmitting genetic information from one generation to the next.
DNA is solely involved in protein synthesis.
DNA has no impact on genetic variation.
What is the difference between genotype and phenotype?
Genotype refers to the physical appearance; phenotype is the genetic makeup.
Genotype is the genetic constitution; phenotype is the expressed traits.
Genotype is the observable characteristics; phenotype is the underlying DNA.
Genotype is the sum of environmental influences; phenotype is the inherited traits.
Define the term allele.
A gene is a type of chromosome.
An allele is a type of protein.
An allele is a variant form of a gene.
An allele is a complete set of genes.
What is the function of ribosomes in a cell?
To produce energy for the cell
To store genetic information
The function of ribosomes in a cell is to synthesize proteins.
To transport nutrients within the cell
How do mutations affect genetic traits?
All mutations result in visible changes to an organism's appearance.
Mutations can create variations in genetic traits by altering DNA sequences, potentially affecting protein function and trait expression.
Mutations have no impact on genetic traits or their expression.
Mutations only cause harmful effects without any benefits.
What is the process of protein synthesis?
Transcription of RNA to DNA
The process of protein synthesis involves transcription of DNA to mRNA and translation of mRNA to protein.
DNA replication to mRNA
Translation of protein to DNA
Describe the structure of a eukaryotic cell.
A eukaryotic cell is characterized by a rigid cell wall and no membrane-bound structures.
A eukaryotic cell has a defined nucleus, membrane-bound organelles, and includes structures like the plasma membrane, cytoplasm, mitochondria, and more.
Eukaryotic cells are always unicellular and do not have organelles.
A eukaryotic cell lacks a nucleus and has only ribosomes.
