Cell Biology

1. How do evolutionary biologist explain why there are two different ways of handling the pyruvate produced from glycolysis? Be sure to relate your answer to the nature of the Earth 3.5 billion years ago. 2. Explain at a biochemical level how wine is made and compare it to your activity of rapidly opening and closing your ha

Genetic Biology

1. You are in a lab that is studying the process of DNA replication. You are particularly interested to know what exactly happens at the replication fork. To answer this question, you have set up a series of DNA replication reactions in test tubes using physiological buffers and conditions. However, the student that you have hir

DNA template strand

A portion of an exon of a eukaryotic protein-coding gene has the following sequence on the template strand: 5'-AGTCAAGCATCCCTTA-3' What is the sequence of the non-template strand written in the 5'-3' orientation? What is the sequence of the corresponding region of the mRNA? , what is the amino acid sequence of the corres

Using DNA in Criminal Behavior

Today, scientific advances are being made at an astounding rate, and nowhere is this more evident than in our understanding of the biology of heredity. Using DNA as a starting point, do you believe there are limits to the knowledge people should acquire? Defend your answer. Because genetics is important to so many aspects of hu

DNA

1. Explain the process that DNA replicates by. Why is it so important that it is carried out in this matter? In explaining the actual process, refer to the possible choices that the scientist considered: conservative, semi-conservative and dispersive. 2. Speciation is a concept that mean one species becoming 2 or more by a pr

Chromosone

A male who has an allele for HD (Huntingtons Disease) mates with a woman who is phenotypically normal. What proportion of thier children will carry the trait (meaning have it but not show the symptons at any time in their life) and what proportion of their children will actually have the disease along with the trait? Some fam

Chromosone

Hair color, eye color and widows peak are all Mendelain dominant recessive traits. If a couple who is heterozygous (both of them mind you) for each of the three traits what are the odds that they will have a child that has dark hair (Dom), Blue Eyes (Rec) and a widows peak (Dom). I think the answer should be a fraction with the

Chromosomes

Two normal parents have 3 children, one a normal girl, one a normal boy and the other boy with hemophilia. If the affected son marries a girl whose father also had hemophilia, what are the overall chances of having a hemophiliac child? A male from India carries an odd trait for hairy ears that is based on the Y chromosome. As

Amino acids and protein structures are considered.

There are four questions to be answered: 1. What type of amino acid side chains would you expect to find folded on the interior of a globular protein? What kind of experimental evidence supports this claim? 2. Which amino acid lacks a stereoisomer and which has more than one asymmetric carbon? 3. What property of th

Genetics

How come we age and die while the genome is immortal? What is telomerase?

Ion channel Study Guide

A Post synaptic ionotropic receptor permenant to only one ion is known to be inhibitory (Activation of the receptor generates an IPSP). Which of the following Ions might pass through such an Ion channel Calcium Sodium Potassium Chloride glucose I am confused can you please explain

General Biology Questions

Chagas disease c. trichomoniasis d. toxoplasmosis e. giardiasis Which of the following alga contains chlorophyll a and abundant phycobilins? a. green alga b. red alga c. brown alga Which organelle allows euglenoids

Molecular Biology (Nucleic Acids and the Genetic Material) Multiple Choice

1. Which scientists first gave experimental evidence that DNA is the genetic material? A Avery, MacLeod, and McCarty who repeated the transformation experiments of Griffith, and chemically characterized the transforming principle. B Garrod, who postulated that Alcaptonuria, or black urine disease, was due to a defective enz

DNA structure of viruses and cancer is illustrated.

In mice, there are viruses that are known to cause cancer. You have a pure preparation of virus DNA, a pure preparation of DNA from the chromosomes of mouse cancer cells, and pure DNA from chromosomes of normal mouse cells. Virus DNA will specifically anneal with cancer-cell DNA, but not with normal-cell DNA. I then explore t

Part of the lab final

I cant figure out what i am suppose to do for this assignement that we are to do. it says to apply each lab that we have done in the class to our career . for example the lab on osmossis and diffusion how would i make three applications for that lab?
