Question

A9. The proteinaceous a. telomere structure shown at the center of the picture above is called the b. scaffold c. nucleosome d. centromere e. chromosome band A10. Eukaryotic RNA polymerases are different from prokaryotic ones in that only eukaryotic a. need the help of a lot of general "TF's" to recognize promoters b. add nucleotides sequentially in a 5' to 3' direction on the new RNA c. require a template d. contain multiple protein subunits e. use ribonucleotide triphosphates to synthesize RNA All. The two strands of the DNA are considered "antiparaltel" because a. The two strands differ in sequence b The phosphates cause the two strands to repel each other c. The sugar-phosphate backbone runs in opposite directions on the two strands d. the bases on the two strands complement each other by hydrogen bonding on the A12. During translation, protein synthesis moves from growing protein. on the mRNA and from a. 5'to 3'; N-terminus to C-terminus b. 5' to 3'; C terminus to N terminus c. 3'to 5': N-terminus to C terminus d. 3'to 5: C terminus to N terminus e. In both directions on both molecules The "first" part of the mRNA is the a. 5'UTR b. first intron c.3 UTR A13. d. start codon e. terminator

Explanation / Answer

A9. (OPTION B) is scaffold because it has many protein and other macromolecules binding sites and helps in signalling pathways.

A 10 (OPTION A) Eukaryotic polymerase requires to recognise tata box.which acts as the promoter with the help pf many transvription factors or TFs. Which help in recognizing TATA box and initiating transcription.

A 11.(OPTION D)
The bases of DNA are complementary to each other
Adenine always hydrogen bonds with thymine.
Guanine hydrogen bonds with cytosine.

A 12.(OPTION A) Amino acids always get translated from 5' to 3' direction starting from amino terminal to carboxy terminal.

A 13 . (OPTION A). 5' utr is the first part of an mRNA followed by coding region which starts with a start codon
