<span>The genetic code is redundant, that means same genetic code is present in multiple times, in each cell. it acts as "nature's safety net" because if we happen to lose a part of our body or genetic material, it can be regenerated using the remaining part which contains the same genetic code.</span>

N-linked glycans are attached to proteins through N-acetylglucosamine or N-acetyl galactosamine to the amide side chain of _____
taurus [48]

Answer:

Asparagine

Explanation:

Glycans are structures made up of chains of simple sugar molecules joined together by chemical bonds. N-linked glycosylation, is the attachment of an oligosaccharide, sometimes referred to as glycan, to the amide nitrogen the amino acid asparagine (Asn) residue of a protein, in a process called N-glycosylation. This linkage is most of the time important for the structure and function of the the protein they are linked to.

What do the variables in the Hardy-Weinberg equation represent? p p2 q q2 2pq frequency of the homozygous recessive genotype arr
kompoz [17]

Explanation:

In Hardy-Weinberg equilibrium...

p^{2} + 2pq +q^{2} = 1

p represents the dominant allele frequency

q represents the frequency of the recessive allele

q^2 = the genotypic frequency of the homozygous recessive

p^2= the genotypic frequency of the homozygous dominant

2pq= the frequency of the heterozygous genotype

Further Explanation:

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences form new alleles, and affect the corresponding mRNA and thus the protein encoded. Along with genetic drift, selective mating and natural selection, evolution may occur within populations.

Some alleles become fixed within a population over time. In Hardy-Weinberg equilibrium for a specific gene that is not undergoing evolution- allelic frequencies are stable over several generations. During this period, mutations do not occur within the population.

Habitat destruction, and thus habitat fragmentation, is the major cause of declining biodiversity; the second major cause is ___
alekssr [168]

Habitat destruction, and thus habitat fragmentation, is the major cause of declining biodiversity; the second major cause is <u>Invasive Species</u>.

The process by which a natural ecosystem can no longer support its native species is known as habitat destruction. Reduced biodiversity and species abundance result from the displacement or death of the creatures that once occupied the area. The loss of biodiversity is mostly caused by habitat degradation.

An imported organism that overpopulates and damages its new habitat is referred to as an invasive species. Even though the majority of imported species are neutral or helpful to other species, invasive species have a negative impact on habitats and bioregions, harming their ecology, the environment, and/or their economy.

The most frequent methods for invasive plants, animals, microorganisms, and other species to spread to new ecosystems are thought to be human activities like those involved in international trade and the pet trade.
