Exploring the Process of DNA Replication

What is the role of histones in the organization of DNA?

• They provide energy for DNA replication.

• They help in unwinding the DNA strand.

• They act as spools around which DNA winds to form nucleosomes.

• They replicate the DNA molecules.

What is the structure formed by DNA wrapped around histones called?

• Chromatin

• Nucleosome

• Chromosome

• Helicase

Which enzyme is responsible for unwinding the DNA double helix?

• Nuclease

• Polymerase

• Helicase

• Ligase

How is the lagging strand of DNA replicated?

• Using RNA primers only

• Without enzymes

• In fragments

• Continuously

What molecule carries the genetic code from DNA to the ribosome?

• tRNA

• mRNA

• rRNA

• RNA polymerase

During transcription, which DNA base is replaced in the RNA copy?

• Guanine

• Cytosine

• Thymine

• Adenine

What is the role of ribosomes in protein synthesis?

• They replicate DNA.

• They unwind DNA strands.

• They synthesize RNA molecules.

• They assemble amino acids into proteins.

Which molecules bring amino acids to the ribosome?

• DNA polymerase

• mRNA

• tRNA

• rRNA

What is the process called where RNA is translated into a protein?

• Transcription
