Can anyone tell me what the # of DNA fragments are?
Svetach [21]

Answer:

1. 3

2. 2

3. 3

4. 3

5. 3

6. 3

The total number of fragments is 17

Explanation:

What the image shows is 6 columns of DNA sequences. It looks like the annotations represents cut sites for restriction enzymes. Restriction enzymes cut at defined sequences. The cut site is represented by the horizontal line (see attached pic, red arrows).

That means any time there is a horizontal line, a new fragment is made. Remember that the DNA is double stranded, so the cuts made will produce what we call "overhangs" or "sticky ends" where they are uneven in length.

Column 1

There are 2 cut sites on each strand, producing 3 fragments

(TGGGC) (CTAGGGCACAT) (TCGAAC)

(ACCCGGATC) (CGTGTAAGCT) (TC)

Column 2

There is 1 cut site on each strand, producing 2 fragments

Column 3

There are 2 cut sites on each strand, producing 3 fragments

Column 4

There are 2 cut sites on each strand, producing 3 fragments

Column 5

There are 2 cut sites on each strand, producing 3 fragments

Column 6

There are 2 cut sites on each strand, producing 3 fragments

Provide explanations of genotypes and phenotypes.
Korvikt [17]
The phenotype is the physical appearance of an organism, while the Genotype is the genetic composition of an organism. Phenotype is observable and are the expression of the genes of an individual. So even the organism with the same species may differ, with a minute difference in their genotype. This is the main difference between the two.

We can notice one’s hair colour, eye colour, height, weight, skin colour, etc. but cannot look at genes responsible for these characters, so the observable physical look is the phenotype while the unnoticed genes responsible for such characters present in the DNA of cell of the individual is genotype.

To explain the above lines, here is the simple example of a pure red colour flowering plant (RR) is crossed with the white colour flowering plant (rr). The result of the Genotype of the F1 generation will be – Rr (Hybrid red colour), and the Phenotype of the F1 generation will be the – Red colour flowering plant.

Genotype and phenotype are the two very closely related and similar-sounding words, but their meaning is different. Our earth has a dynamic variety of organisms, present in soil, water and on land. But as the genome of each organism is different, and so there phenotypes also whether it’s their colour, height, weight or other morphological features.
