Explanation:
Cancer cells do not contain the capacity to undergo
- a regular cell cycle where they only undergo cell division in response to external signals within their environment, i.e. regulation.
- differentiation into specialized cell types, with different physical traits; together they can't form different tissues.
Multiple mutations in several protooncogenes and tumor suppressor genes are required to form cancer.
Cancer-causing genes, or oncogenes, develop from protooncogenes which regulate normal cell division. They may undergo mutations that alter gene expression, disrupt cell regulation and lead to the transformation of normal cells into tumor cells- their resulting proteins are abnormal or not formed. Tumor suppressor genes, which can halt unregulated cell growth and division, may also become mutated.
Each individual inherits 2 copies of a gene from their parents- a single mutation in one of these does not directly lead to cancer. Multiple activated oncogenes, in turn produce damaged, non functional proteins and together contribute to forming cancers.
Further Explanation:
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.
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 affect the corresponding mRNA and thus the protein encoded.

Coccidioides immitis is not a member of domain bacteria.
Coccidioides immitis is a dimorphic fungus that causes the fungal disease; coccidioidomycosis. Coccidioides immitis is mainly found in soils and it exists in two different forms (saprophytic and parasitic). When Coccidioides immitis enter a host, their spores separates from the hyphae and develop into round structures (spherules) that divides to form endospores which causes infection within the host.
Answer:
<u>c</u>
Explanation:
Grows and develops over lifetime cannot be considered as a characteristic of life.
<u>Characteristics of Life</u>
- <em>Can move and respond to stimuli</em>
- <em>Breathes air to survive</em>
- <em>The ability to reproduce</em>
Aloe Ferox is 20 times higher in bitter sap containing Aloin and has twice the number of amino acids than Aloe Vera. Also the ability to stimulate regeneration of cells necessary for healing and repairing skin tissue. However, the bitter sap or extract, drained from the cut leaves, is used primarily for its laxative properties.
Answer:
Lysozyme is an enzyme that breaks down bacterial cell walls and is found in your tears, mucus, and saliva. A mutation occurs in the gene for lysozyme that results in a lysine (a positively charged amino acid) being substituted for an arginine (also a positively charged amino acid). Do you think that the mutant lysozyme will function similarly to the normal lysozyme?
No, because all changes in protein primary sequence result in functional differences
Explanation:
Protein sequence are known to be complimentary to each other, slight changes or sudden changes would affect the function as well as those work in antagonizing way with one another.
