Questions and Answers Already Passed
What is the role of DNA polymerase in DNA replication?
✔✔DNA polymerase adds nucleotides to the growing DNA strand and proofreads for errors
during replication.
How does the structure of DNA contribute to its function?
✔✔The double helix structure of DNA allows for easy replication and storage of genetic
information in a stable form.
What is a mutation, and how can it affect an organism?
✔✔A mutation is a change in the DNA sequence that can lead to altered proteins, potentially
causing changes in an organism's traits or health.
Why is RNA necessary for protein synthesis?
✔✔RNA carries the instructions from DNA to the ribosomes, where proteins are made, acting as
a messenger between the genetic code and protein production.

, How does the process of transcription differ from replication?
✔✔Transcription copies a segment of DNA into RNA, while replication duplicates the entire
DNA molecule to pass genetic information to daughter cells.
What is the function of a promoter in gene expression?
✔✔A promoter is a DNA sequence that signals RNA polymerase where to begin transcription of
a gene.
How do ribosomes contribute to protein synthesis?
✔✔Ribosomes translate mRNA into proteins by reading the genetic code and facilitating the
assembly of amino acids into a polypeptide chain.
What is the role of tRNA in translation?
✔✔tRNA carries specific amino acids to the ribosome and matches them with the corresponding
codons on the mRNA during protein synthesis.
How do genes determine an organism's traits?
✔✔Genes encode proteins that perform various functions in the cell, and these proteins
ultimately influence an organism’s physical and biochemical traits.
