Answer:

Peptidoglycan.

Explanation:

Archae are eubacteria are both shows the characteristic of the prokaryotic organisms. They both lacks the well defined nucleus and membrane bound cell organelles.

Although they show various similar characteristics, but they have remarkable difference in their cell wall structure. The cell wall of bacteria contains peptidoglycan with lipid bilayer of fats. The cell wall of archae lacks peptidoglycan and contains monolayer or bilayer made of phytanyl.

Thus, the correct answer is option (1).

denis23 [38]

Answer:

In some mice, fur color is inherited through incomplete dominance. The colors that are possible are black fur, white fur and grey fur. Grey is the trait that is inherited through incomplete dominance. Scenario: a grey fur male mouse and a grey fur female mouse have 8 babies. The offspring that result are: 2 black fur, 5 grey fur and 1 white fur. But this is not what is statistically expected from that cross. Explain why this is still a probable outcome. This is as a result of mutation

Explanation:

Mutation is the sudden change of a gene, from the above explanation mating of an incomplete grey fur dominance with an incomplete grey fur dominance should not have had offspring with 2 black fur, 5 grey fur and white fur. Normal mating should have produced also an incomplete grey fur dominant offspring

Question 4 (1 point)<br> Why are nonsense mutations rare?
Lostsunrise [7]

When a DNA sequence alteration results in a stop codon rather than a codon that specifies an amino acid, it is known as a nonsense mutation. This is rarely seen in 10% of patients with genetic disease.

<h3>What is nonsense mutation?</h3>

A nonsense mutation in a DNA sequence causes a premature stop codon, also known as a nonsense codon, in the transcribed mRNA as well as a shortened, ineffective, and typically nonfunctional protein product.

Because stop codons, also known as nonsense codons, signal the completion of protein synthesis rather than encoding for an amino acid, they are the source of the term "nonsense mutation."

Examples of illnesses for which nonsense mutations have been implicated as contributing factors include: Cystic fibrosis (produced by the G542X mutation in the cystic fibrosis transmembrane conductance regulator); (CFTR) Beta-globin (thalassemia) Hurler disease.

If bicoid mRNA is injected at the anterior end of an egg from a bicoid mutant mother, what would the phenotype of the resulting
JulijaS [17]

If the larva had one head at the posterior pole, it would be normal. The larva would have two heads, one at the front of its body and the other in the center.

What is bicoid mRNA?

When translated, bicoid protein forms a morphogen gradient that shapes the embryo's head and thorax if bicoid mRNA localizes to the anterior of the Drosophila egg.

How does the egg's bicoid RNA influence development?

According to recent research, Bicoid specifies the anterior of the Drosophila embryo in two different ways. It initially suppresses posterior development. It accomplishes this by attaching to and preventing caudal RNA, which is distributed throughout the egg and early embryo, from being translated.
