Back

Adenine

Front

During which phase of the cell cycle does the cell prepare for mitosis?

Back

G2 phase

Front

Why is it important that gene expression is regulated?

Back

To prevent the cell from producing unnecessary molecules, wasting energy and raw materials, and to allow for cell differentiation.

Front

What type of mutation is represented by the change from ATTTGAGCC to ATTGAGCC?

Back

Deletion - Frameshift

Front

What is transcription?

Back

The process of copying a segment of DNA into RNA.

Front

What is the role of ribosomal RNA (rRNA) in protein synthesis?

Back

rRNA forms the core of the ribosome's structure and catalyzes protein synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

Front

What is a frameshift mutation?

Back

A mutation that occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame.

Front

What is the function of messenger RNA (mRNA)?

Back

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