C) Sperm and eggs are haploid. All others are diploid.

The answer for this question is letter C. It is true that sperm and eggs have half the chromosomes as other cells. <span> The sperm and/or the egg cell each only has 23 chromosomes, half of the original number, so that when they join to form a zygote when fertilization occurs, the zygote will have a total of 46 chromosomes, like every cell in a human does.</span>
The others cannot be the right answer for the following reasons:
A - <span>The complexity of an organism dos not depend on the number of chromosomes.
B - Nucleus is the only place where you can find chromosomes.
D - DNA and other proteins makes up the chromosomes.</span>

Describe the genetic mutations that you think occurred in the cancer cells that were responsible for the phenotypic differences
ruslelena [56]

ANSWER:

Most types of cancer are believed to begin with a random genetic mutation. This is followed by mutations, which endow the cancer cells with properties allowing them to grow without normal controls to become a tumor.

Mutation is any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment.

Genetic Mutations that lead to cancer cell formation can occur in two forms:

1. GROWTH-PROMOTING GENES are commonly mutated in cancer cells, becoming SUPER-ACTIVE and producing cells that are too strongly stimulated by growth receptors.

2. Mutations can INACTIVATE the genes that suppress cell proliferation or those that signal the need for apoptosis. These genes are known as TUMOR SUPPRESSOR GENES.

What has to happen before mitosis begins?
Leokris [45]

Mitosis is simply a stage in a cells life cycle, which could be broken down further into stages of mitosis. The rest (so not mitosis) is know as Interphase and is where the cell does its normal function, so if it's the cell is in a region of muscle it would contract/relax as normal etc.

Immediately before mitosis (or M phase) is what's know as G2 phase, where the G stands for growth and is where particular gene pathways are expressed to promote growth of the volume of DNA (chromosomes are duplicated, so from 46 to 92). At the end of this stage is a checking process where the DNA is scrutinised for any errors, if all is okay then the cell can proceed to mitosis, if not then the process is stopped so that errors in copying the DNA can be fixed. This is know as a restriction point and the cell must meet the requirements to pass. This is often seen as a way cells can prevent damage being replicated and therefore interfering with normal cell processes. When cells are cancerous they are able to override this and therefore divide and spread the damaged DNA.
