How do scientists use recombinant DNA technology to produce the drug insulin.
Dvinal [7]
Since diabetics are not able to make enough insulin, scientists use gene engineering to make it for them. they insert the gene that codes for the production of insulin in the plasmid (circular DNA of bacteria ) to create recombinent DNA, and the bacteria will asexually reproduce, making more and more of the insulin in a short amount of time! hope this helped it took me a long time to understand the whole process in this unit!

In humans, six fingers (f) is the dominant trait; five fingers (f) is the recessive trait. if the father is heterozygous for six
rodikova [14]

The probability of the offspring of a heterozygous father and homzygous mother having five fingers is 50%.

<h3>How to calculate genotype of a cross?</h3>

According to this question, a gene coding for the number of fingers in humans is involved. The allele for six fingers (F) is the dominant trait while the allele for five fingers (f) is the recessive trait.

If a cross between a heterozygous father that posseses a genotype of Ff and a homzygous mother that posseses a genotype of ff, the following offsprings will be produced:

  • Ff
  • Ff
  • ff
  • ff

This shows that the probability of the offspring of a heterozygous father and homzygous mother having five fingers is ½ (50%).
