1). A cell is in the process of transcription. The single strand of DNA that is being copied has the sequence TAC GCA TTA CCC. Indicate the mRNA strand and then the tRNA strand that will be synthesized from this DNA strand listing the correct sequence of bases. What amino acids are translated? Describe why this step is important in the process of producing proteins. Explain how gene expression is regulated.
2). Explain how nondisjunction may be related to Down syndrome. Describe four syndromes that result from inheritance of an abnormal sex chromosome number.
3).What is biodiversity and why is this important to our survival?
4).Your friend knows that you took Human Biology and studied genetics. She asks you to explain a Punnett square to her. How do you explain how a Punnett square is read? Apply the following terms to your explanation: dominant, recessive, heterozygous & homozygous, one-trait & two-trait crosses, dihybrid cross and probability.
Explain why people addicted to methamphetamines often sleep very little, suffer extreme mood swings, and become very thin.
many health care organizations have implemented the electronic health record ehr system. assess the issues that are
The green algal ancestors of plants lived in an aquatic environment, contained chlorophyll a and b, and had cell wall composed mainly of cellulose. Land plants also have chlorophyll a and b and have cellulose cell walls.
What is a transcription factor? Give an example of a transcription factor and a possible role it may play in the aging process.
Migration of a deleterious allele into a population can result in a stable equilibrium presence of that allele in the population. Discuss how the intensities of selection and migration influence that equilibrium. What would happen to the allele if..
An analyzer is studying a gene that codes for a very small polypeptide phe his gly cys gly. He treated the cells with different mutagens with the results to the protein.
Double-stranded DNA molecules have negatively charged sugar-phosphate backbones, and a major and minor groove into which the chemical groups of the bases project.
Describe how those mutations can potentially result in cancer. Make sure you list all references used for information and images.
In humans, ABO blood groups are determined by three alleles: alleles IA and IB are codominant and both are dominant to the third allele i. MN blood groups are determined by two codominant alleles M and N.
For a given reaction, G = -4 kcal/mole and the energy of activation for the uncatalyzed reaction = 5 kcal/mole. You add an enzyme, after which the activation energy decreased to 3 kcal/mole.
after completing the life cycle cost worksheet you should have some idea of how much co2 you are releasing into the
Given the following allele frequencies estimate the genotypic frequencies and explain how you calculate the genotypic frequencies from the allele frequencies for both generations it would be.
