Leviafan [203]1 year ago

An insertion or deletion of a nucleotide base that alters the reading frame is known as a frameshift mutation.

A point mutation only affects one amino acid and does not alter the frame.

The reading frame may or may not move as a result of the insertion or deletion of a nucleotide or combination of nucleotides. The mutation is referred to as a non-frameshift mutation if it does not result in a shift in the reading frame.

The addition or deletion of certain nucleotide base-pairs from the DNA molecule is referred to as an insertion or deletion.

The reading frame may or may not move as a result of the insertion or deletion of a nucleotide or combination of nucleotides. The mutation is referred to as a non-frameshift mutation if it does not result in a shift in the reading frame.

On the other hand, a mutation is known as a frameshift mutation if the reading frame does shift. Where it occurs will determine how it changes.

ipn [44]

Since the Pitx1 gene codes for a protein crucial im lower limns development, a mutation occurring near Pitx1 gene will affect refikjs around the lower limbs but not those far away from it.

<h3>What are mutations?</h3>

Mutations refers to alterations or error that occur which change the original sequence of nucleotides in a DNA molecule.

The Pitx1 gene is a gene that codes for a protein that involved in development of the lower limbs.

A mutation near but outside of the coding region of Pitx1 may cause a loss of pelvic fins without pleiotropic effects on the pituitary gland and jaw because the pelvic fins form part of the lower limbs whole the jaws and the pituitary gland are not found in the lower limbs.

Therefore, the mutation occurring near Pitx1 gene will affect regions around the lower limbs but not those far away from it.

Humans can take up available space, disrupt systems, or change water supplies in an ecosystem. What conclusion can you make abou
alexandr402 [8]

Answer:

Human activities affect the flow of energy and matter in an ecosystem and alter the energy balance in ecosystems through the unsustainable nature of what they do.  The energy flow is affected in several ways as a result of pollution, overpopulation, deforestation, burning fossil fuels, etc. Such changes have stimulated soil erosion, climate change, causing water unfit to consume, poor quality of air and so on. When humans cause a change in the energy balance, they impact the ability of the ecosystem to respond and adapt to changes in the environment. It is like getting a cut, but it never heals and grows bigger instead.

What clean water regulation do you think has had the greatest impact on water quality in the United States? In a 3-5 sentences,
Kay [80]

Answer:

The Clean Water Act (CWA) can be considered as one of the effective program which impacted the water quality in the United States. Under this Act, quality standards for surface water were generated.

This Act has set wastewater standards for the industries and it ensures that industries do not pollute the clean water. The Clean Water Act (ACT) made it unlawful to discharge any pollutant in waters and set a fixed amount for it. Beyond that amount, polluting water is considered to be illegal.
