When the dna ladder twists the way it normally does the shape of the molecule is called a double helix. The DNA  is made of nucleotides consisting of a de-oxyribo sugar, a phosphate group and one of the four nitrogen base.

Adenine pairs with Thymine with 2 hydrogen bond and Guanine pairs with Cytosine with 3 hydrogen bond .This provided the clue the DNA molecule is a double helix , shaped like a twisted ladder.

The sidwa of the DNA ladder are made up of alternating sugars and phosphate groups. A is always paired with T and G is always paired with C. Paired bases are held together by weak bonds called hydrogen bonds, and when the DNA ladder twists the way it normally does, the shape of the molecule is called a double helix.

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.

Based on the results of the experiment as well as what you learned about the mechanism of gene transfer between bacterial cells,
cestrela7 [59]

Since, the experiment is not given but on the basis of the mechanism of genetic transfer this question can be answered.  

Answer:

The mechanism of gene transfer is important and beneficial for bacteria in the adverse environment conditions. The different mechanism of gene transfer are conjugation, transformation and transduction.

The ampicillin resistance gene is present on the plasmid DNA and not on the chromosomal DNA. Only conjugation is the mechanism in which the plasmid DNA is transferred from one bacteria to another bacteria. The ampicillin resistance gene is transferred from Strain II to strain I means from the bacteria that has the ampicillin resistance gene to the bacteria that has no ampicillin resistance gene in it.
