What is the effect of a mutation in mRNA on protein production?

Back

A mutation in mRNA can lead to the production of a protein with a different identity.

Front

What is the role of DNA in protein production?

Back

DNA contains the instructions used to make proteins.

Front

What carries the instructions for making amino acids in a protein?

Back

The sequence of nitrogen bases on the mRNA carries the instructions for making amino acids.

Front

What gas is produced by the freshwater plant Elodea during photosynthesis when placed in direct light?

Back

Bubbles of oxygen are produced as a result of photosynthesis.

Front

How do cells from the same organism have different shapes and functions?

Back

During differentiation, different parts of the DNA in each type of cell are activated, resulting in different structures and functions.

Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries 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 amino acids to the ribosome and matches them to the coded mRNA message.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is 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 significance of protein folding?

Back

Protein folding is crucial because the shape of a protein determines its function in biological processes.
