Question

Part D Now can you predict nucleotide quantities in a hypothetical scenario with more than four different types of nucleotides? An alien species was discovered that has DNA comprised of 6 diferent bases: binds to C: A binds to and X binds to Y Approximately 10% of this allen genome is comprised of nucleotides containing Cand 22% is comprised of nucleotides containing Y. Given this information, calculate the percentage of the alien genome that is comprised of nucleotides containing GTA and X) of the alien genome is comprised of (b) of the ten genome is comprised of c) of the wen genome is comprised of A of the sen genome is comprised of Enter your answer as four numbers, soported by commas (example:12, 24, 32, 10).

Answer 1

Ans. Part -D Acc. to question A binds to T a binds to c x binds to y. Acc- to Ch Chargaff's nule, double stranded a DNA has CA=%T, %42%C and here C. A=T % G=CC % X=64 7 Given that 16% =C and 22 % = 4 This, "A +% T t f G t%C+%.x+%4 = loq % ATOT 16 + C +% X + 22 =lco ble know that G=c thus 16 9.6=16%.c X=4 so 22% Y = 22%.X -A=I

9. A+9T + 16+ 16 + 22 +22=lco % A+YT 76 YA+9T 24 A=I thus 9A +%A % A & A =% 1 =12 12 So, a ) 16 b) 12 I. of the alien genome is comprised of G. % of the alien genome is comprised of T. % of the alien genome is comprised of % of the alien genome comprised of x. c) d) 12 22 is % of C, T, A and X N 16, 12, 12, 22 Part - B bind togethe Deoxyribonucleotides ther to from polynucleotides: This bond accurs between the phosphate group of nucleotide and the 3 of of another nucleotide type of bond formed this interaction called a Lphosphodiester bond position The type is nucleotide project the 2.) The nitrogenous bases of each I into double helix. They form complementary base pairs through the formation % hydrogen bonds with bases the opposite DNA strand on

3.) Adenine complementarily binds with thy mine and forms (how many ?) type ? hydrogen bonds 2 (what [ 4.) Guanine complementarily complementasily binds with binds with cytasina and forms ( how many ?) (what type ?) bonds hydrogen 27 s-strain R-strain Visulent Non-voulent = Smooth under microscope Rough cappearance Live -strain t mice Mice die Because s-stain ü virulent Heat killed sastrain Mice line Head killing the s-strain makes it non-vroulent. 3 Living R-strain Mice live The R strain mice is not visulent

5 Heat killed s-strain. + Injected into mice Living R strain Mice die A tocans forming factor from the heat killed S-strain made the R strain visulent Correct chemical structure of a dinucleotide composed of A and G and the G and the complementary dinucleotide composed of I and c in antiparallel (ox upside down) fashion ! - H 31 T A A and I have two hydrogen bonds T G and c have three hydrogen bonds === o 31 OH second option is correct.
