If a DNA strand has a nucleotide base sequence
Nuetrik [128]

Answer:

T-A-A-G-C-G-T-A would be the sequence of it's complementary strand.

Explanation:

This is because there are 4 nucleotide bases which math with only a certain other nucleotide, which are

  • A as in Adenine matches with T as in Thymine.
  • T as in Thymine matches with A as in Adenine.
  • C as in Cytosine matches with G as in Guanine.
  • G as in Guanine matches with C and in Cytosine.

A good way to remember this is, the letters that are only made of nothing but straight lines (A, T), match with each other, and the letters that have curves in them (C, G), watch with each other.

Hope this helps!

As discussed previously, the ABO locus in humans has three alleles, where IAand IBare co-dominant and i is recessive to each. Su
Ivahew [28]

Answer:

Explanation:

using the formula p² + 2pq + 2pr + q²+ 2qr + r² = 1 where p is IA allele is 0.35 and q is IB allele is 0.15.

Thus, the expected frequency of people with type AB blood in this population will be (2pq) = 2 x 0.35 x 0.15 = 0.105

b. The expected frequency of people with type A blood will be p² + 2pr = where r is found using the formular p + q + r = 1 = 1 - (p+q) = 1 - (0.35+0.15) = 0.5

Thus, we have the expected frequency of people with type A blood to be     (0.35² + 2x0.35x0.5) = 0.4725.

c.    <u> p² + 2pr</u> + <u>2pq </u>+ <u>q² + 2qr</u> +<u> r²</u>

       AA AO      AB      BB BO     OO

         1850       180        635      2335

frequency of IA- p = (1850 + 180/2) / 5000 = 0.388

frequency of IB- q = (635 + 180/2) / 5000 = 0.145

frequency of i- r = 2335/ 5000 = 0.467.

since r² = 2335, r = √2335 = 48.32

using the formula p + q + r = 1
