To determine whether the mutations in the seven strains leading to the wingless phenotype are in the same gene, your lab sets up

complementation tests. You obtain the following results ("+" indicates that complementation was observed; "-" indicates that no complementation was observed).
mutation 1 2 3 4 5 6 7
1 -
2 - -
3 + + -
4 - - + -
5 + + - + -

The question is incomplete as it lacks the question and has only information regarding the question. however, the correct question is as follows :

How many different genes are contributing to the wingless phenotypes in these mutant fly strains?

Answer:

The correct answer is - Two genes.

Explanation:

In the given question there are  two mutation groups based on the given seven results:

1st group :

Mutations 1, complement with 2,4, and 7  and also complement each other, thus, are on the same gene.

2nd group:

Mutations 3, 5, and 6 did not complement each other but complemented with mutations 1, 2, 4, and 7. Thus, these three mutations are present together on a different gene.

The purple spots on colorless background of corn kernels observed by barbara mcclintock were the result of _______.
vitfil [10]

The purple spots on the colorless background of corn kernels observed by Barbara McClintock were the result of the transposition of the Ds elements out of the color gene.

<h3>What are the genetic elements found in corn?</h3>
  • A transposable element is removed from one spot in the DNA and inserted into a different site in the DNA during the process of genetic transposition, which allows genes to shift their location on chromosomes.
  • The first recognized genetic instability was caused by genetic transposition.
  • The size of the tissue patch displaying the reversion phenotype increases as a reversion event happens earlier in the kernel development.
  • Barbara McClintock saw purple dots on maize kernels with an otherwise colorless background.
  • These spots were caused by the Ds components of the color gene being transposed.
  • The wild-type (purple) phenotype manifests itself in cells where Ds from the color gene "C" sequence has been lost.

Hence, Barbara McClintock discovered purple patches on the colorless backdrop of maize kernels due to the transposition of the Ds elements out of the color gene.

What structure is made up of microfilaments and microtubules and provide structure to the cell?
son4ous [18]
Microtubules, microfilaments & intermediate filaments. The cytoskeleton is unique to eukaryotic cells. It is a dynamic three-dimensional structure that fills the cytoplasm. This structure acts as both muscle and skeleton, for movement and stability.
