In the outbreak of malaria, the frequency of the recessive allele for the HbS gene will increase. The correct option is A.

<h3>What is the HbS gene?</h3>

HbS is a beta-globin gene known as sickle hemoglobin.

It causes sickle cell disease in humans.

The disease is expressed by two HbS variants or one HbS variant or one another beta-globin gene.

Malaria is caused by the plasmodium parasite, which is present in the saliva of the mosquito.

Thus, the correct option is A, the frequency will increase.

Svetllana [295]

Answer:

The correct answer will be option-DNA polymerase can only add nucleotides to the free 3' end

Explanation:

DNA replication process produces the exact copy of DNA which requires various enzymes. The function of adding a nucleotide to the daughter strand is performed by the enzyme called DNA polymerase.

The DNA polymerase enzyme catalyses the process of DNA replication which requires energy provided by the dNTP. The enzyme adds new nucleotides at 3'-OH end of the DNA which favour the reaction energetically.  

Thus, the new DNA strand appears to be elongated in the 5' to 3' direction.

Which of these characteristics apply to viruses? Select all that apply.
Olegator [25]

The characteristics that apply to viruses are;

  • Viruses are made of RNA or DNA.
  • Viruses have a protein coat

<h3>What are viruses?</h3>

Viruses are microscopic non-cellular structure consisting of a core of DNA or RNA (nucleic acid) surrounded by a protein coat (capsid).

A virus is considered as by non-living because it requires a living host cell to replicate, and often causes disease in the host organism.

Therefore, the characteristics that apply to viruses are;

  • Viruses are made of RNA or DNA.
  • Viruses have a protein coat

A mutation within a gene that will insert a premature stop codon in mrna would _______
AveGali [126]

A mutation within a gene that will insert a untimely cease codon in mRNA would result in a shortened polypeptide chain.

<h3>What occurs if there is a untimely end codon?</h3>

Thus, nonsense mutations occur when a premature nonsense or end codon is added in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins

<h3>What mutation motives untimely cease codon?</h3>

In genetics, a nonsense mutation is a factor mutation in a sequence of DNA that effects in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and normally nonfunctional protein product.

Describe the type of plants that serve as pioneer species, intermediate species, and climax community species in secondary succe
MissTica
In secondary succession, the pioneer species are plants that are adapted to exploit disturbances rather than bare rock. They typically include plants such as grasses, birch trees, and fireweed. Organic matter from the pioneer species improves the soil so other trees and plants can move into the area.
