Biology

Answer:

The answer is:

d. In every species, DNA is a simple repeating polymer made up of the same four nucleotides.

Explanation:

Chargaff’s rules are based in the quantitative relationship of the nucleotides (adenine, guanine, cytosine and thymine) that form part of the double strand of DNA.

One of the rules states that the amount of adenine (A) is the same as thymine (T), and that the amount of guanine (G) is the same as cytosine (C). A=T, G=C

Being said in another way: the total amount of purine bases it’s the same as the total amount of pyrimidine bases. (A + G= C + T).

The second rule states that the composition of DNA (the amount of nucleotides) is different from one species to other, but nor within species.

White raven [17]

Answer:

1. The chi-square statistic is 0. The p-value is 1. Not significant at p < .05.

The chi-square statistic with Yates correction is 0.0642. The p-value is .800028. Not significant at p < .05.

Explanation:

2. By generating large sets of data the ratio will remain same (F1 = 3:1, F2 = 9:3:3:1) according to the Chi-Square analysis. In actual reality, it fails to justify by giving a probability value of 1 that is impossible due to the exceptions of Co-Dominance and Incomplete Dominance...

Find the remainder when p(x) = –2x5 + x4 + 5x3 + 4x + 1 is divided by (x - 2).
borishaifa [10]

The remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1.

To solve the question above, we make use of the remainder theorem.

Remainder Theorem: It states that if a function F(x) is divided by (x-a), the remainder is F(a).

From the question,

Given:

  • Dividend ⇒ p(x) = -2x⁵+x⁴+5x³+4x+1
  • Divisor ⇒ (x-2)

in view of the above and applying the Remainder theorem, The remainder will be p(2)

  • p(2) = -2(2⁵)+2⁴+5(2³)+4(2)+1
  • p(2) = -64+16+40+8+1
  • p(2) = 1

hence the remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1

What is the Difference between DNA &amp; RNA?
Travka [436]
DNA is deoxyribonucleic acid while RNA is ribonucleic acid !

DNA has base pair of adenine guanine thymine and cytosine.....while RNA has adenine guanine cytosine and uracil !

DNA is always double helix while RNA is mainly single helix !

DNA contains genetic info for 99℅ of organism while RNA is being catalytic and unstable than DNA is only present as genetic information holder in 1℅ !

DNA does not involve in protein synthesis directly but RNA has to !

for more difference, comment !
