NRSG 357: Cancer Care – Questions & Answers (100%)What is interphase? Right Ans - Period where the cell spends most of its
time, primarily have cell growth occur, but no cell division, this is where most
cells live, expect cancer
What is G1 phase? Right Ans - the first part of interphase, longest phase of
the cell cycle, where we produce extra organelles such as ribosomes and
proteins
What is G0 phase? Right Ans - no more cell division-cells go here
sometimes instead of S
What is S phase? Right Ans - synthesis phase, DNA synthesis-this is where
the DNA replicates
What is G2 phase? Right Ans - another growth phase where we are more
directly preparing for mitosis
What is mitosis? Right Ans - active cell division
What are cyclin-dependent kinases (CDK)? Right Ans - -Protein kinases
that regulate the cell cycle (mitosis; kinases add a phosphate group);
-works together with cyclins;
-always present in a cell, but their default function is to be inactive
How are CDK activated? Right Ans - -Cyclin proteins
-specific cyclins made at specific times

What is tumor suppressor gene? Right Ans - regulate cell growth
What is neoplasm? Right Ans - A new growth of abnormal tissue that is
uncontrolled and progressive
What is a neoplastic? Right Ans - cancer
What is cancer? Right Ans - -A group of diseases characterized by
uncontrolled and unregulated cell growth
-is an umbrella term
-ALL are genetic (a mutation on the cells DNA); is genetic but not always
hereditary
Who does cancer affect? Right Ans - affects all ages, ethnic groups, both
genders
Is cancer hereditary? Right Ans - -Hereditary NOT ALWAYS (less common;
5-10%);
-if it is inherited will develop cancer at an earlier age
