Single Gene Traits in Humans
For each of the traits listed below:
1. Indicate your expression of the gene by circling the appropriate phenotype.
2. Identify the two possible alleles for each gene.
3. Indicate whether you exhibit the dominant or
1. Describe the genetic mutation associated with sickle cell anemia. What gene does
it occur in? What type of mutation is it? How does the protein that results from
the mutated gene differ from that of the normal gene?
In the hemoglobin gene, instead of h
Nature of Cancer
Benign Tumors not life threatening tumors, not particularly dangerous
-not defined by their size
-can be removed easily by dermatologists
Malignant Tumor [Cancer] Invasiveness determines whether or not it is can
Interphase: Interphase, the first step of mitosis, lasts for about 90% of the time of the cell
cycle. This process can be divided into three different stages, the first being G1; the first
gap. In this phase, the cell supplies itself with more pro
-weakness and fatigue
-unexplained fevers and infections
-excessive and unexplained bruising
-bone pain, joint pain
-swelling in the lower limbs or the abdomen
-weight loss or loss of appetite
What type of cells and tissue
The first step in the process of a genes translation into a protein is transcription.
Transcription is the transfer of genetic information from DNA to RNA. First, the DNA
strands have to be separated in order for one of them to serve as the template for t
2a. At first the line is going towards the top but then it begins to go down. As it continues
to go down there are a couple of straight lines but then it goes back up in 1995.
2b. From 1960 to 1975 the deer population increased but it began to decrease fr
1) What are some factors that we discussed in class prevent cells from dividing uncontrollably?
When cells divide, they are surrounded by each other, so they can only fill up the empty spaces.
2) How do cells communicate? What role might that play in cell
Somatic Cell typical body cells that has 46 chromosomes
Chromosomes the structures that contain most of an organisms DNA
Homologous Chromosomes two chromosomes composing a pair; both carry genes
controlling the same inherited characteristics
Locus on a ch
Somatic cells survival; perform mitosis
Germ cells reproduction; only found in testes and ovaries; very small in comparison to
the rest of the cells that make up the body; perform meiosis; produce cells that are called
Gametes ex: sperm and egg pr
