DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine
yanalaym [24]

It is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand.

  • Deoxyribonucleic acid (DNA) is a biological molecule with two strands. Each strand is made up of a sequence of nucleotides. The DNA nucleotides are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).

  • In a DNA molecule, Adenine forms an hydrogen bond with Thymine i.e. A-T, while Guanine forms an hydrogen bond with Cytosine i.e. G-C.

  • Therefore, it is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand. For example, a strand with ATGCGTACGAT will form the following sequence: TACGCATGCTA

Which of the following is most likely to decrease biodiversity?
frez [133]

Answer:

Add native plants to a suburban garden because you are adding already flourishing wildlife

Sea Urchins are primary consumers because they eat the kelp

Sun -> Grass -> Rabbit because grass lives off of photosynthesis from the sun and rabbit eats the grass

I think there would be more biomass in grass because there is a lot more spread throughout the savannah while elephants are way bigger there is less of them.

There are two alleles, B and b, at a gene locus in a population at Hardy-Weinberg equilibrium. The relative frequency of the dom
viva [34]

Answer:

210

Explanation:

Frequency of dominant allele is represented by "p"

and frequency of recessive allele is represented by "q"

Given

p = 0.7

Thus,

q = 1-p\\q = 1 - 0.7 \\q = 0.3\\

As per Hardy Weinberg's second equation of equilibrium -

p^2 + q^ 2 + 2pq = 1\\

Substituting the given values in above equation, we get -

0.7^ 2+ 0.3^2 + 2pq = 1\\2pq = 1- 0.49-0.09\\2pq = 0.42

So the total number of heterozygous individual is equal to

0.42 * 500\\= 210
