Large amounts of sewage cause a lot of algae to grow, which lowers the concentration of carbon dioxide in the water. *

Once a product can serve the present moment and remain useful for an indefinite period without polluting the environment, or getting reduced in value, it can be said to be SUSTAINABLE.

How does a mutation in the DNA affect the way proteins are made?

Vikentia [17]

Explanation:

B.) A mutation in the DNA results in a change in the mRNA and, ultimately, to a different protein structure.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells.

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

somatic: these only occur within certain cells, and arise from environmental factors such as UV light
hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They exist solely to encode and carry out protein synthesis.

The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand in transcription. These are then translated into proteins in ribosomes. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

They are maintained within cells, as they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring a protective advantage.

<em>e.g. sickle cell anemia, a disease caused by a mutation, confers protection against the disease malaria.</em>

You isolate cells from a tumor and study them. You observe that the cells continue dividing, even when DNA is damaged, when the

seraphim [82]

Answer:

Cells are cancerous

Explanation:

Cancer is a disease which is caused by the continuous division of the cells without differentiation. The differentiation is the important process which determines the fate of the cell in the body that is it provides the function to the cell it has to perform.

In the given question, when the cells are dividing continuously and form a tumour even in the low condition therefore it can be concluded that the cells are cancerous or will be the cause of cancer.

Thus, Cells are cancerous is correct.
