Explain how conversion of a normal somatic cell into a malignant one requires multiple mutations.
MAXImum [283]

Answer:

Mutation is the alteration in the DNA base sequence in an organism.it may be due to chemical or environmental effect on the somatic cells..

Generally ,most cancers are caused by mutation in DNA components of abnormal cells.

Basically proto-oncogene is responsible for cell growth and cell division before mitosis in normal healthy cells;thus its codes for the main protein specific for cellular functions in normal cells. Therefore for mutation to occur mutations in mutiple genes is important. .

Basically 2 p53 alleles must be mutated,

2 BRCA1 allele must be mutated,

and 1 mutated allele of HER2 mus be mutated.

All these multiple mutations in these genes are needed.

Describe the pattern of inheritance that is most likely associated with a mutation in the MT-ND5 gene. Explain why individuals a
Andreas93 [3]

Answer:

this gene is a mitochondrial gene and therefore it is maternally inherited

Explanation:

The MT-ND5 gene is a gene of the mitochondrial genome that provides instructions for synthesizing a protein called NADH dehydrogenase 5, which is part of the complex I (the first enzyme of the respiratory chain). In most multicellular organisms, the mitochondrial DNA (mtDNA) is inherited from the mother (i.e., maternally inherited), whereas nuclear DNA (i.e., nuclear genome) is inherited equally from both parents. For example, mitochondria in human sperm are usually destroyed after fertilization. In consequence, mitochondrial mutations are transmitted by maternal inheritance, and individuals, therefore, cannot be heterozygous for mitochondrial genes.
