Back

codon

Front

Why can’t cells directly use the energy from glucose?

Back

Cells cannot use glucose directly because it has too much energy.

Front

When a cell uses ATP for energy, the ATP molecule is converted to __________.

Back

Front

Through what structure does mRNA exit the nucleus of a cell?

Back

nuclear pore

Front

What is the portion of an RNA molecule that does not contain information for making a protein and is removed prior to the RNA molecule leaving the nucleus?

Back

intron

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the sites of protein synthesis where amino acids are assembled into proteins.

Front

Define transcription in the context of protein synthesis.

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is the difference between exons and introns?

Back

Exons are coding regions of RNA that are expressed, while introns are non-coding regions that are removed.

Front

What is ATP and why is it important for cells?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.
