Explain how an SNP may produce a restriction fragment length polymorphism (RFLP).

Biology
1 answer:
iVinArrow [24]3 years ago

Answer:Single nucleotide polymorphisms or SNPs (pronounced "snips") are DNA

sequence variations that occur when a single nucleotide (A,T,C, or G) in the

genome sequence is altered (point mutation).

SNPs do not cause disease, but they can help determine the likelihood that someone will develop a particular disease.

Because single base mutations can either create additional restriction sites or destroy pre-existing sites, DNA preparations from different individuals frequently exhibit different patterns of size distribution of restriction fragments that hybridize with a particular probe. These differences are called

restriction fragment length polymorphisms (RFLPs).

What proteins are crucial for creating and maintaining DNA replication forks? Choose the best explanation.
timurjin [86]

Answer:

Explanation:

The correct answer is (B) Helicase creates the replication fork; single-strand binding proteins keep the single strands from reuniting. The replication fork is established by the enzyme DNA helicase, which separates the two complementary strands of a DNA molecule

3. Could a man with type AB blood be the father of a child with type O blood? Explain your answer utilizing Punnett squares (see
svlad2 [7]

Answer:

No

Explanation:

Both A alleles and B alleles are dominant over the O alleles. This means that both parents must have an O allele present to even have a chance of having a child with type O blood. Lets say the mother has type O blood with the father having type AB blood. The possible combination would be: AO, BO, AO, BO. The punnett square should look like this:

        A          B

O     AO        BO

O     AO        BO

The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angle
Nadya [2.5K]

Answer:

2(8x^2-13x+10)

Explanation:

There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.

Let's let A represent the measurement of one of the those angles in our pentagon.

The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.

But we are also given that this equals 40x^2-65x+50.

So that means 5A=40x^2-65x+50.

If we divide both sides by 5 we can find what one of our angles is in terms of x.  So let's do that A=8x^2-13x+10.

So we want to know the sum of two our angles, we want to know what is A+A or 2A.  2A=2(8x^2-13x+10).  To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.

Viefleur [7K]

Answer: The correct answer is- B) Ecosystem.

Ecosystem can be described as a group of living organisms present in a particular area that are interacting with each other as well as the non living components of that environment.

In other words, it is the interaction between biotic ( living such as plants and animals) and abiotic ( non living such as temperature, air, water) components of an environment.

Example- Pond ecosystem, lake ecosystem.
