Final Exam Review

Front

What copies instructions in DNA and carries these to the ribosomes in the cytoplasm?

Back

mRNA (messenger RNA) is responsible for copying instructions from DNA and transporting them to the ribosomes for protein synthesis.

Front

Where does translation happen in the cell?

Back

Translation occurs in the ribosomes, where the mRNA is translated into a protein.

Front

What type of organism obtains the energy it needs by feeding on other organisms?

Back

Heterotrophs are organisms that obtain energy by consuming other organisms.

Front

At what level does life begin?

Back

Life begins at the cellular level, where cells are the basic units of life.

Front

In the carbon cycle, what gas do producers take in?

Back

Producers take in carbon dioxide during the process of photosynthesis.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) brings amino acids to the ribosomes during translation, matching them to the codons on the mRNA.

Front

What is the function of rRNA in the cell?

Back

rRNA (ribosomal RNA) is a component of ribosomes and plays a crucial role in protein synthesis.

Front

Define autotrophs.

Back

Autotrophs are organisms that produce their own food using light or chemical energy, such as plants through photosynthesis.

Front

What is the process by which cells convert glucose into energy?

Back

Cellular respiration is the process by which cells convert glucose into energy, producing ATP.

Front

What is the significance of the nucleus in a cell?

Back

The nucleus contains the cell's genetic material (DNA) and controls cellular activities.
