How may a gene be defined

2 answers:

The general definition of a gene is some heredity that is passed on from a parent to an offspring. Scientifically speaking, the transfer involves a sequence of nucleotides that forms part of the chromosome. This sequence of nucleotides is a DNA.

Thus, the answer would be

A. a segment of DNA

A. a segment of DNA

Further explanation

Genes are inheritance units of living organisms. Its physical form is that the sequence of DNA attached to a protein, polypeptide, or strand of RNA that incorporates a function for the organism that owns it. the trendy boundary of genes may be a specific location within the genome that's associated with inheritance and may be linked to functions as a regulator, target transcription, or other functional roles. the utilization of genes in everyday conversation is commonly intended for alleles: the selection of variations available by a gene. Although allele expressions will be similar, people more often use the term allele for organic phenomenon that's phenotypically different.

DNA may be a supermolecule that stores all the unique biological information of each physical object and a few viruses. Its chemical structure is within the sort of complex macromolecules consisting of three sorts of molecules, namely pentose sugar (deoxyribose), orthophosphoric acid, and nitrogen bases. the most role of DNA molecules is that the long-term storage of knowledge.

DNA segments that carry genetic information are called genes, but other DNA sequences that have structural purposes, or are involved in regulating the utilization of genetic information.

DNA can replicate ie form copies of itself. Each DNA strand contains a particular base sequence. Each base is additionally connected by sugar and phosphate molecules. If the bottom forms a rung (horizontal), then the sugar and phosphate molecules form the vertical a part of the ladder.

zlopas [31]

Answer:

SA Node

Inter-nodal Pathways

AV Node

AV Bundle

Bundle Branches

Purkinje Fibers

The SA nodes functions first for setting pace for the heart, then the inter-nodal pathway make link b/w SA and AV node. AV node is site of delay when contraction of atria occurs. AV bundle is the mean of electrical link b/w atria and ventricle. The conveying of impulse to the inter-ventricular septum occurs through bundle branches, while conveying of impulse throughout and along the walls of ventricle occurs through Purkinje fibers.

Does human intervention affect small-scale ecosystems differently than large-scale ecosystems?

sdas [7]

Answer: No

According to BBC, Human activities such as harvesting plants and hunting animals can unbalance the flows and cycles within those [SMALL SCALE ECOSYSTEMS ]ecosystems. Tree-felling may lead to soil erosion and a loss of habitat. Lack of shade and moisture in the soil can result in desertification.

According to National Geographic, Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

kherson [118]

Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Gene dosage is modified is a major contributor to this phenomenon.

In the field of genetics, we can define gene dosage as the quantitative measure or copies of a particular gene that is present in an organism. Abnormalities in the gene dosage at a particular location can cause severe damage to the resulting phenotype.

Gene dosage can lead to chromosome duplications if the copy number or gene product is more and it can cause deletions if the copy number or gene product is less. Such complications will result in abnormal phenotypes or inviable gametes. For example, in Down's syndrome, the person has a modification of the 21st chromosome as there is one extra 21st chromosome present. This leads to a variety of diseases and defects in the person.

Although a part of your question is missing, you might be referring to this question:

Chromosome duplications and deletions frequently result in abnormal phenotypes or inviable gametes. Which factor is a major contributor to this phenomenon?

a. Recessive diseases are unmasked by additional copies.

b. The genes are found in a novel arrangement.

c. Gene dosage is modified.
