How do radiation and chemotherapy affect cancer cells?

elixir [45]

Answer:

They destroy the DNA or RNA

Explanation:

Cancer drugs work by damaging the RNA or DNA. The faster the cancer cells divide, the more likely it is that chemotherapy will kill the cells, causing the tumor to shrink. They also induce apoptosis. Radiation therapy is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors. The radiations also induce apoptosis. Cancer cells whose DNA is damaged beyond repair stops dividing and die. The damaged cells die, they are broken down and removed by the body.

ad-work [718]

Answer:

The complete set of an organism's or population's genes. B. genome

A variation at a single position in a DNA sequence among individuals of the same species. F. single nucleotide polymorphism (SNP)

A lab instrument used to precisely measure and move small amounts of liquid. E. micropipette

A procedure that makes thousands of copies from a small sample of DNA. J. polymerase chain reaction (PCR)

A word that means to copy. I. amplify

An enzyme that copies a single strand of DNA. A. DNA polymerase

A single, short piece of DNA that must be present to copy a DNA template. D. primer

Viruses that infect bacteria. C. bacteriophages

Short enzymes that cut DNA samples at a specific base sequence. H. restriction endonucleases (restriction enzymes).

A process that separates pieces of DNA by their size using an electrical current. K. gel electrophoresis

A series of chemical reactions that generate a cellular response. L. signal transduction

A molecule that binds to another molecule. G. ligand

Explanation:

Genome is also defined as a full set of genetic material in an organism.

SNP is usually referred to a substitution of a single nucleotide at a specific position in the DNA.

Micropipette is used for the precise measurement and for the exact amount of liquid delivery.

PCR is a widely used technique in molecular biology, used for the amplification (replication) of DNA fragments. It is performed thanks to heat-resistant enzyme (Taq polymerase) through the cyclic reactions. Polymerases are enzymes that add nucleotides in order to make chanis-polymers of nucleic acid (polymerization) and they require short DNA segment (primer) in order to start the polymerization. Restriction enzymes are enzymes that recognize and cut DNA at specific site (restriction site) and are widely used in DNA cloning.

Signal transduction is a set of steps from signal binding to cell response that are transmitted through the cell. It usually starts with ligand-receptor binding.

One of the main source of sediment in flowing water is soil erosion.

Explanation:

Soil erosion is the washing away of top most layer of soil due to various reasons.

Agents of soil erosion are: wind, water, animals, ice or gravity.

Water is one of the biggest agent or cause of soil erosion. Water carry lots of energy in its motion. When water moves from any area it carries away topmost layer of soil with it. The soil that is being carried away by water is sediment.

When this water reach river, lake or any other water source, sediments carried by them enters that source of water. Sediment results in water pollution.

A mutation that disrupts the ability of an animal cell to add polysaccharide modifications to proteins would most likely cause d

sashaice [31]

Answer:

Golgi apparatus and extracellular matrix

Explanation:

The Golgi complex lies at the heart of the secretory pathway and is responsible for modifying proteins and lipids, as well as sorting newly synthesized molecules to their correct destination. As a consequence of these important roles, any changes in its proteome can negatively affect its function and in turn lead to disease.

Disruption of specific transport steps between the endoplasmic reticulum (ER), Golgi complex, endosomal-lysosomal system and the plasma membrane all can have dramatic consequences on the cell, and increasingly defects in the molecular machinery regulating membrane traffic are being linked to hereditary diseases.

Any changes to the proteome of the Golgi complex would affect its homeostasis and consequently the flux of proteins trafficking through it.

One possible consequence of mutations in Golgi complex proteins is that they cause gross changes in the morphology of the entire organelle and protein mislocalization, which together result in functional problems such as impairment of glycosylation.

Genetic studies of humans and mice continue to highlight the nonredundant mechanical role of components in complexes that anchor cells to extracellular matrices. At the same time, recent data provide exciting insights into, critical roles of transcription factors in regulating differentiation and function of matrix-producing cells.
