In a genetics lab, researchers are studying a DNA sequence extracted from a rare species of deep-sea bacteria. They analyze the nucleotide composition and find that the sequence contains equal amounts of adenine (A) and thymine (T), as well as equal amounts of guanine (G) and cytosine (C). What conclusion can the researchers draw about the structure of this bacterial DNA?

Which event occurs during prophase I of meiosis that contributes to genetic diversity?

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?
