Answer:
Chromosomal Mutation
Explanation:
The development and function of an organism is in large part controlled by genes. Mutations can lead to changes in the structure of an encoded protein or to a decrease or complete loss in its expression. Because a change in the DNA sequence affects all copies of the encoded protein, mutations can be particularly damaging to a cell or organism. In contrast, any alterations in the sequences of RNA or protein molecules that occur during their synthesis are less serious because many copies of each RNA and protein are synthesized.
Geneticists often distinguish between the genotype and phenotype of an organism. Strictly speaking, the entire set of genes carried by an individual is its genotype, whereas the function and physical appearance of an individual is referred to as its phenotype. However, the two terms commonly are used in a more restricted sense: genotype usually denotes whether an individual carries mutations in a single gene (or a small number of genes), and phenotype denotes the physical and functional consequences of that genotype.
Answer:
a."Alkylating agents are toxic to tissues that have rapidly dividing cells."
Explanation:
In the given example the patient is about to begin chemotherapy with a bifunctional alkylating agent.
when the two dna strands are cross linked they will not separate for dna replication which will halt the cell division process so rapidly dividing cells will stop dividing and die
Moreover,Chemotherapeutic agents, also known as antineoplastic agents, are used to prevent the growth of fast-growing cells, usually in the sense of malignancy, directly or indirectly.
Therefore, Chemotherapeutic agents are Alkylating agents that are toxic to tissues that have rapidly dividing cells
So, this statement by student indicates an understanding of his chemotherapeutic agent.
Meiosis is a special type of cell division in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells.
Answer:
T cells are born from hematopoietic stem cells, found in the bone marrow. Developing T cells then migrate to the thymus gland to develop (or mature). T cells derive their name from the thymus.
