In a research study on aging and cell division, scientists focus on the function of telomeres. They observe that cells with shortened telomeres experience reduced replicative capacity. What specific role do telomeres play in maintaining genomic stability and cellular health?

Which pH value represents a basic solution on the pH scale?

In a molecular biology lab, researchers are studying the replication of the lagging strand in DNA. They observe that DNA synthesis occurs discontinuously in short fragments. Which enzyme is primarily responsible for linking these fragments together?

During which phase of mitosis do chromosomes align in the middle of the plate of the cell?

Which structure is found in prokaryotic cells but not in eukaryotic cells?

Which of the following characteristics is typical of prokaryotic cells?

A microbiologist is studying a bacterial gene involved in antibiotic resistance. They discover a mutation in the gene that changes a codon from CAA (encoding glutamine) to UAA, which is a stop codon. How will this mutation likely affect the synthesis of the protein?

Which phase of the cell cycle comes before mitosis?

In a research lab studying DNA replication, scientists investigate the enzyme responsible for removing RNA primers and replacing them with DNA nucleotides. Which enzyme are they primarily focusing on in their study?

A medical researcher is studying a gene associated with a rare genetic disorder. They identify a mutation in the gene that changes a codon from GAA to AAA, resulting in the substitution of glutamine (Gln) with lysine (Lys) in the encoded protein. How will this mutation likely impact the function of the protein?
