Monosaccharide b. disaccharide c. trisaccharide d. polysaccharide A26. In eukaryotic mRNAs, the unusual nucleotide, containing 7 methyl guanosine, is found a. Attached to the first transcribed nucleotide, at the 5' end b. Attached to the last transcribed nucleotide, before the po c. At the G in the AUG start codon d. At intron-exon junctions lyA tail A27. In nucleic acids, the term "polarity" refers to the a. Negative charge of the phosphate groups b. Direction of the sugar-phosphate backbone c. Hydrophobicity of the bases d. Tendency to migrate in an electric field e. Helical shape of the molecule A28. In DNA, the base pairs are a. A with T; G withC b. A with C; G withT c. A with G; C withT d. A with U; G with C e. A with A; G with T or C A29. Within eukaryotic genes, the proximal promoter elements are located a. More than a thousand base pairs away from the transcript start b. Within the transcribed region of the gene c. Within the 5'UTR d. Upstream of the TATA, within a few hundred base pairs e. Between the TATA and the transcript start site A30. DNA replication begins at a. Promoters b. start codons originsExplanation / Answer
A 23. The -10 and -35 sequences are present within the promoter. The promoter is a DNA sequence that transcription apparatus recognises and bind. They are recognised by RNA polymerase sigma factor. Hence, the correct option is b. RNA polymerase binding site.
