Write the complementary sequence for the following DNA sequence, in order from 3' to 5': 5′−CGATATTGAGCTAAGCTT−3′ Use all capita
sveta [45]

Answer:

3'-GCTATAACTCGATTCGAA-5'

Explanation:

The DNA is a macromolecule formed by two strands of polynucleotides forming a double helix.

These chains are composed of monomers called nucleotides, there are 4 different types in DNA, called nitrogenous bases: two purines, guanine (G) and adenine (A) and two pyrimidines, thymine (T) and cytosine (C). They are joined by covalent bonds in each chain.

These bases are complementary: G with C, and A with T between the two strands by hydrogen bonds making the double-stranded DNA molecule.

A sequence 5'-CGAT-3' is equivalent to a sequence written 3'-ATCG-5' , because the 5' and 3' notation defines the direction of reading. If one strand is noted 5' to 3', then the complementary strand will be from 3' to 5' in the same sense.

So, all we need to do is write the complementary bases from the 3' end to 5':

5'-CGATATTGAGCTAAGCTT-3'  

3'-GCTATAACTCGATTCGAA-5'  (answer)

Describe: Imagine a rock on a beach and a rock on the side of a mountain. How
Vesna [10]

Answer:

  • mountainside: temperature extremes have more influence
  • beach: wind and waves have more influence

Explanation:

It depends on what you mean by "factors that control weathering" and where the beach and mountain are located.

If we assume that the rock on the mountain is at a place that has seasonal snow, and the beach is in a temperate climate, then we can make these observations.

The rock on the mountainside will be "weathered" by freezing and thawing, and by plant growth (roots). These will tend to enlarge any cracks in the rock, breaking it apart. While the mountainside may be windy, that wind may not carry particles that would tend to erode the rock surface.

__

The rock on a beach will be most affected by wave and water action, tending to smooth any exposed surface. Freezing and thawing action is less common, due to the moderating influence of the water on the local weather. In some cases, plant growth may also be a factor. Wind may pick up beach sand, further tending to smooth any exposed surfaces.

Rabbit ears can be either shorter floppy where short ears or dominant over floppy ears there are 653 individuals in a population
Dvinal [7]

Answer:

frequency of dominant and recessive alleles - 0.6, 0.4

frequency of individuals with dominant,  heterozygous and recessive genotypes - 0.36, 0.48, 0.16

Explanation:

Given -

Short ears (S) is dominant over floppy ears.

Total population of rabbits = 653

Population of rabbits with floppy ears = 104

Population of rabbits with short ears = 549

Frequency of rabbits with floppy ears is equal to

\frac{104}{653} \\= 0.159

Thus as per Hardy weinberg's equation, frequency of recessive phenotype is represented by q^2\\

Thus,

q^2 = 0.159 =0.16\\q = \sqrt{0.16} \\q = 0.4

Thus,

p = 1-q\\p = 1-0.4\\p= 0.6

Frequency of rabbits with short ears only

= p^ 2 \\= 0.6^2\\= 0.36\\

Frequency of heterozygous rabbit (Ss)

p^2 + q^2 + 2pq = 1\\0.16 + 0.36 + 2pq = 1\\2pq = 1 - 0.36-0.16\\2pq = 0.48
