Front

What is a product of cellular respiration?

Back

Carbon dioxide is a product of cellular respiration.

Front

What characteristic of life is demonstrated when a caterpillar transforms into a butterfly?

Back

This transformation is an example of growth and development.

Front

What is the main reason for the rapid spread of antibiotic-resistant bacteria?

Back

The bacteria can exchange genetic material with other bacteria, allowing for the spread of antibiotic resistance.

Front

What is the corresponding mRNA sequence for the DNA sequence TGC AAA CGT?

Back

The corresponding mRNA sequence is ACG UUU GCA.

Front

What genotypes correspond to roundworms with a roller pattern of motion?

Back

Roundworms with a roller pattern of motion have the genotypes RR or Rr.

Front

Define cellular respiration.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is the role of DNA in living organisms?

Back

DNA contains the genetic instructions for the development, functioning, growth, and reproduction of all known living organisms.

Front

Explain the concept of genetic material exchange in bacteria.

Back

Bacteria can exchange genetic material through processes like conjugation, transformation, and transduction, which can lead to traits like antibiotic resistance.

Front

What is the difference between dominant and recessive alleles?

Back

Dominant alleles express their traits even when only one copy is present, while recessive alleles require two copies to express their traits.

Front

What is the significance of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.
