A benign tumor is not a malignant tumor, which is cancer. It does not invade nearby tissue or spread to other parts of the body the way cancer can. In most cases, the outlook with benign tumors is very good. But benign tumors can be serious if they press on vital structures such as blood vessels or nerves. A malignant primary tumor is more dangerous because it can grow quickly. It may grow into or spread to other parts of the brain or to the spinal cord. Malignant tumors are also sometimes called brain cancer.

You have isolated a bacterium from a contaminated river but you are unable to culture it in the laboratory. Which method could you use to identify the organism
Answer:
DNA sequencing
Explanation:
DNA sequencing is the method which can be used in order to identify the bacterium that was isolated from the contaminated river. DNA sequencing is the process in which the sequence of nucleotides is determined that is present within a DNA molecule. For identifying the bacterium, the sample of bacteria is collected. After sample collection is completed, genomic DNA is extracted from the bacteria and DNA sequencing will be done of that bacteria.

Given the following sequence of DNA, write the correct sequence of complementary DNA bases.
TACCGATAA
Given the following sequence of DNA, write the correct sequence of complementary mRNA.
ACCGTACTG
Given the following sequence of DNA write the correct sequence of amino acids.
ATAGGCGTA
Answer:
1. ATGGCTATT
2. UGGCAUGAC
3. mRNA: UAU-CCG-CAU, amino acids: tyrosine(tyr)-proline(pro)-histidine(his)
Explanation:
For DNA, the complementary bases are T=A and C=G. This means every time you see one of these letters, the corresponding letter goes with it. For mRNA, the bases are T=A, A=U, C=G. It is the same except now, there should be no "T" in the mRNA sequence. With amino acids, you would first code for the mRNA sequence, every three letters being the amino acid sequence. To find the amino acid, you would look at a codon chart unless your teacher wants you to memorize them. The first three letters of the amino acid are the abbreviation.

What you know about DNA and protein CER.
- has to explain the structure and function of DNA and proteins.
Explanation:
DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes.
In order for a protein to be an integral membrane protein it would have to be which of the following?
a. hydrophilic
b. hydrophobic
c. amphipathic
d. completely covered with phospholipids
e. exposed on only one surface of the membrane
Answer:
amphipathic, with at lest one hydrophobic region
Explanation:
For a protein to be an integral membrane protein it would have (C) : amphipathic
Amphipathic is a chemical property of a protein molecule whereby it has both hydrophilic and hydrophobics portions in the its molecule. ( i.e. It contains water soluble and non-water soluble portions ) and for a protein to be an integral membrane it has to posses both water soluble and non-water soluble portions in its molecule.
Hence we can conclude that for a protein to be considered an integral membrane protein it will posses an Amphipathic property.

Explain why:
A lever used to lift a heavy box has an input arm of 4 meters and an output arm of 0.8 meters. What is the MA of the lever?
Answer:
Mechanical advantage = 5
Explanation:
Given the following data;
Length of input arm = 4 meters.
Length of output arm = 0.8 meters.
To find the mechanical advantage;
[tex] Mechanical \; advantage = \frac {Length \; of \; 1nput \; arm}{Length \; of \; 0utput \; arm} [/tex]
Substituting into the formula, we have;
[tex] Mechanical \; advantage = \frac {4}{0.8} [/tex]
Mechanical advantage = 5
