This increases by burning stuff, and also decreasing the amount of trees to change it.

Travka [436]

By haphazardly introducing a transgene harboring a disease-causing mutant variant of the HTT gene into the genome of a mouse or primate, it is possible to produce an animal model with the majority of the symptoms of this condition. Here option B is the correct answer.

Huntington's disease is an uncommon, genetic condition that results in the gradual degeneration of brain nerve cells. Huntington's illness, which frequently results in mobility, cognitive, and psychological problems, has a substantial impact on a person's functional capacities.

A DNA region known as a CAG trinucleotide repeat is involved in the HTT mutation that causes Huntington's disease. Three DNA-building building pieces that are repeated several times in a row make up this region.

Complete question:

Huntington's disease is a dominant disease caused by the expansion of the trinucleotide repeat region of the Htt gene that results in the production of a Huntingtin protein with an expanded number of glutamines. An animal model with most features of this syndrome could be created by

A - knocking in a wild-type copy of the Htt gene to a mouse or primate genome.

B - randomly inserting a transgene containing a wild-type allele of the Htt gene to a mouse or primate genome.

C - randomly inserting a transgene containing a disease-causing mutant allele of the Htt gene into a mouse or primate genome

D - knocking out one copy of the wild-type Htt gene from a mouse or primate genome.

E - knocking out both copies of the wild-type Htt gene from a mouse or primate genome.

The letter X in the diagram below represents what enzyme used in the process shown?

Anvisha [2.4K]

<u>Answer</u>: Option D. RNA polymerase.

<u>Explanation</u>:

Transcription is the process which is used to produce RNA from a DNA template.
The enzyme involved in the process of transcription is <em>RNA</em> <em>polymerase</em> which is responsible for separating the DNA strands and making an RNA which is complementary to the DNA.
RNA polymerase joins the nucleotides in the newly formed RNA strands by utilizing the energy released from the cleavage of the additional phosphate bonds that are removed by it.
The RNA polymerase dissociates from the DNA only after the process of transcription is complete.
