AP Biology for Grade 9 FAQs

1. What is the central dogma of molecular biology?
Ans. The central dogma of molecular biology states that genetic information flows from DNA to RNA to protein. This means that DNA is transcribed into RNA, which is then translated into proteins.
2. What is the role of DNA polymerase in DNA replication?
Ans. DNA polymerase is an enzyme responsible for synthesizing new DNA strands during DNA replication. It adds nucleotides to the growing DNA strand based on the complementary base pairing rule.
3. What is the difference between transcription and translation?
Ans. Transcription is the process of synthesizing RNA from a DNA template, while translation is the process of synthesizing proteins from an RNA template.
4. What are the three types of RNA involved in protein synthesis?
Ans. The three types of RNA involved in protein synthesis are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).
5. What is a codon and how does it relate to protein synthesis?
Ans. A codon is a three-nucleotide sequence on mRNA that codes for a specific amino acid. During protein synthesis, tRNA molecules with complementary anticodons bring the corresponding amino acids to the ribosome based on the codons on mRNA.
6. How does DNA replication ensure the accuracy of genetic information transfer?
Ans. DNA replication involves proofreading mechanisms like DNA polymerase's exonuclease activity to correct errors in nucleotide base pairing, ensuring the accuracy of genetic information transfer.
7. What is the function of RNA polymerase in transcription?
Ans. RNA polymerase is an enzyme responsible for synthesizing RNA from a DNA template during transcription. It helps in unwinding the DNA double helix and adding complementary RNA nucleotides.
8. How does the genetic code determine the sequence of amino acids in a protein?
Ans. The genetic code is a set of rules that specifies the relationship between codons on mRNA and the amino acids they encode. This code determines the sequence of amino acids in a protein during translation.
9. What is the significance of the start codon AUG in protein synthesis?
Ans. The start codon AUG (encoding the amino acid methionine) signals the beginning of protein synthesis and helps establish the reading frame for translation.
10. How do mutations in DNA affect protein synthesis?
Ans. Mutations in DNA can result in changes to the sequence of mRNA codons during transcription, leading to alterations in the amino acid sequence of proteins synthesized during translation.
11. What is the role of ribosomes in protein synthesis?
Ans. Ribosomes are the cellular structures where protein synthesis occurs. They facilitate the binding of mRNA and tRNA molecules, enabling the translation of mRNA codons into amino acids.
12. How does the process of translation differ in prokaryotes and eukaryotes?
Ans. In prokaryotes, transcription and translation can occur simultaneously in the cytoplasm, while in eukaryotes, transcription occurs in the nucleus and translation occurs in the cytoplasm.
13. How do tRNA molecules ensure the accuracy of protein synthesis?
Ans. tRNA molecules have specific anticodon sequences that base pair with mRNA codons and carry the corresponding amino acids to the ribosome, ensuring the accuracy of protein synthesis.
14. What is the significance of the stop codon in protein synthesis?
Ans. The stop codon signals the termination of protein synthesis, prompting the ribosome to release the completed protein chain. It does not code for any amino acid.
15. How does gene expression regulate the production of specific proteins in a cell?
Ans. Gene expression involves the transcription of specific genes into mRNA and the subsequent translation of mRNA into proteins. Regulatory mechanisms like transcription factors and epigenetic modifications control when and how genes are expressed to produce specific proteins.
