Cell Cycle and Meiosis Review

Front

What is genetic variation?

Back

Genetic variation refers to differences in DNA between individuals or populations, which can lead to different traits and characteristics.

Front

What is the relationship between DNA, RNA, and proteins?

Back

DNA controls the production of proteins in the cell through the processes of transcription and translation.

Front

What amino acids are coded by the DNA sequence TAC-TAG-CAT-ACT?

Back

The DNA sequence TAC-TAG-CAT-ACT codes for the amino acids Methionine (Met), Isoleucine (Iso), Valine (Val), and a STOP codon.

Front

What process occurs in both mitosis and meiosis?

Back

The separation of sister chromatids occurs in both mitosis and meiosis.

Front

What is a codon?

Back

A codon is a sequence of three bases in mRNA that codes for a specific amino acid.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA serves as a template for translating genetic information from DNA into proteins.

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome that are connected by a centromere and are separated during cell division.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is the significance of the STOP codon in protein synthesis?

Back

The STOP codon signals the termination of protein synthesis, indicating that the polypeptide chain is complete.

Front

How does genetic variation contribute to evolution?

Back

Genetic variation provides the raw material for natural selection, allowing populations to adapt to changing environments.
