Question

hello, two of these circled answers are incorrect.
1 6. The promoter sequences are the positions that: signal the initiation site of a gene (+1) B) bind the transcriptional factor that is associated with RNA polymerase e) attach the correct nucleotide triphosphate to the template DNA strand D) separate the two DNA strands CUA 7. A particular triplet of bases in the coding sequence of DNA is GAT. The anticodon on the tRNA that binds the mRNA codon is A CỦA B) CTA GAU D) GAT 8. Which of the following statements is true about transcription & translation in culcaryolcs? Par After transcription completion, the RNA is exported directly to cytoplasm for translation without modification process splicing Translation can begin while transcription is still in progress, only in lacten The 'cap and poly A tail are removed in the mature mRNA Added to make wawe w D) The mature mRNA eliminates introns and ligates exons for proceeding to translation process - 9. What is the termination signal of transcription in eukaryotes? The end of the mRNA molecule is reached. BYA stop codon is reached. trarciarias C) The 5' cap is reached. 52inning The poly-A tail is reached. 10. Why might a point mutation in DNA make a difference in the level of a protein's activity? At It might delay the rate of DNA translation B) It might interfere with the transcription process © It might substitute a different amino acid in the polypeptide chain causing it Dy It might result in a gene translocation. to have a different conformation 11. A frame shift mutation could result from A) a base insertion only B) a base deletion only Sy a base substitution only silent or missense D) either an insertion or a deletion of a base 12. What is incorrect description of ribosomes? ATt has 2 subunits made of RNA & proteins 305 + SOS By It has 3 sites A, P. E where the translation takes place zarge om (C) It binds to DNA to start the translation process binas to the ma D) It connects the complementary bases of tRNA and mRNA n

Answer 1

I believe the correct answer to be:

6) Option B) Bind the transcriptional factor that is associated with RNA polymerase.
As transcription factors bind to promoter sequences and help the RNA polymerase perform its function.

12) Option D) It connects the complementary bases of tRNA and mRNA.
As those tRNA carries the appropriate amino acid that is added to the growing chain once the tRNA forms complementary binding to the mRNA.
