Biology Review for S1 Finals

Front

What is a mutation in DNA?

Back

A mutation is a change in the DNA sequence that can alter the amino acid sequence of a protein, potentially affecting its function.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the primary source of energy for photosynthesis?

Back

The primary source of energy for photosynthesis is sunlight.

Front

How is a pedigree chart used in genetics?

Back

A pedigree chart is used to track the inheritance of traits across generations, showing how traits are passed from parents to offspring.

Front

What is transcription in the context of genetics?

Back

Transcription is the process by which mRNA is synthesized from a DNA template.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating mRNA.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll is the pigment that absorbs sunlight, providing the energy needed for photosynthesis.

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that determines how the sequence of nucleotides in DNA is translated into the amino acid sequence of proteins.
