Two humans mate who are heterozygous for earlobe shape where attached earlobes (A) are dominant to free earlobes (a), and earwax
MariettaO [177]

Answer:

3/16

Explanation:

This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).

According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

* Attached earlobe, wet earwax (A_E_) = 9/16

* Attached earlobe, dry earwax (A_ee) = 3/16

* Free earlobe, wet earwax (aaE_) = 3/16

* Free earlobe, dry earwax (aaee) = 1/16

Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.

Put the main steps of genetic engineering in the correct order. i. replicate the new organism ii. isolate the genes from the spe
Finger [1]

These are the five steps in genetic engineering.

  • locating and obtaining the DNA of an organism with a particular trait.
  • cloning the gene responsible for the phenotype.
  • creating a gene with a particular expression pattern.
  • transformation, which involves introducing the gene into a crop plant's cells.
  • Transgene into a background with affluence.

In the process of genetic engineering, DNA extraction comes first. This is achieved by taking a sample of bacteria that contains the desired gene and subjecting it to a series of procedures that isolate DNA from other components of the cell.

What does it mean when we say a gene is "turned off"? What does it mean when we say a gene is "turned off"? The gene is now acti
olga nikolaevna [1]

Answer:

The gene cannot be transcribed and translated into a protein.

Explanation:

Turning off a gene means the gene cannot be transcribed and translated into a protein.

Turning off of genes is a form of gene regulation, a process that controls which genes are expressed or not expressed in a cell.

<u>The expression of genes requires that they are first transcribed from DNA to mRNA in the nucleus and then moved to cytoplasm where they are translated into proteins by the ribosome.</u>

Hence, a gene that will not be expressed has to be stopped from being transcribed amd translated by being turned off by the gene regulation process of the cell.
