DNA Worksheet Trisha McCabe SCI/230 May 8th 20132 Chandreyi Basu‚ PhD Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA made up of units called nucleotides‚ nucleotides are made up of three molecules components‚ a nitrogen base‚ a sugar‚ and a phosphate (Simon‚ Reece‚ Dickey‚ 2010). The nucleotides are joined together by bonds between the sugar of one nucleotide and the phosphate of the next producing

Section 10-2 VOCABULARY REVIEW 1. mRNA carries genetic information from the DNA in the nucleus to the cytosol of a eukaryotic cell. 2. tRNA is a chain of RNA nucleotides that are folded into a hairpin shape and can bind to a specific amino acid. 3. Transcription is the process by which genetic information is copied from DNA to RNA. 4. A promoter is a region of DNA that marks the beginning of the DNA chain that is to be transcribed.

RABIES Abstract: Each year‚ approximately 55‚000 individuals worldwide die from an infection due to the rabies virus. Rabies is a life-threatening disease caused by an RNA virus that is usually transmitted to humans through bites from rabid animals. More recently‚ reports of transmission by means of organ transplantation have been reported. Since human rabies is nearly 100% fatal if prophylactic measures are not followed‚ an increased awareness of who should receive prophylaxis and

Chapter 4: Nucleic Acids and the RNA World 1. 4.1 – What is a Nucleic Acid? * Nucleic acids are made up of monomers called nucleotides * Three components of a nucleotide: 1. Phosphate group—attached to the 5’ carbon 2. Sugar – carbonyl group and several hydroxyl groups 3. Nitrogenous base * The prime (‘) symbols indicate the carbon being is part of the sugar—not attached to the nitrogenous base. * Four different nucleotides‚ each of which contains a different nitrogenous

because the sides are attracted to each other and with out the Single Strand Binding Proteins they would move back together) f. The Replication Fork is formed with the Leading and Lagging strands. g. In the leading strand‚ RNA Primase moves along nucleotides and coats with a RNA Primer that will be used as a homing beacon for the DNA Polymerase. h. DNA polymerase synthesizes the new DNA by adding complementary nucleotides to the template strand. i. DNA polymerase attaches post primase to DNA nucleotides

One Health- Exam One 1. A) Why is the One Health paradigm important? The One Health initiative is a change in basic assumptions that focuses on surveillance of the environment‚ animals‚ and humans to predict occurrence of an outbreak before it happens. This is important in improving the health of communities because preventative measures will be used and it also makes people aware of what could happen if preventative measures were not taken. Scientists and doctors worldwide collaborate to develop

Uncontrolled transposition is deleterious to the cell and thus‚ the frequency of transposition is generally kept to a minimum by various regulatory mechanisms. Describe the FOUR ways that transposition is controlled. Transposition is the movement of a particular fragment of DNA from one part of a genome to another. A transposon is a segment of DNA which is capable of moving from a specific location on a DNA molecule to another location on the same or different molecule. For this reason‚ it is

Ch. 51- FAP: sequence of behaviors that are usually carried through to completion. Habituation:loss of sensitivity to unimportant stimuli. Associative learning: associating one stimulus with another. Class. Conditioning: association of an irrelevant stimulus with a fixed physiological response. Cognition: animal’s ability to perceive‚ store‚ process‚ and use info. from its sensory receptors. Agonistic behavior: contest to determine which competitor gains access to a resource. Ch. 54- Nitrogen fixation:
