How would a pair of sister chromosomes differ from homologous chromosomes?
If the reproductive cell only has 23 chromosomes, then how come all of our body cells (somatic cells) have 46 chromosomes?
Briefly describe the constituent molecules found within a chromosome. You may use a diagram to illustrate your answer. Refer
1. Each cell of the human body contains 46 chromosomes.
a. How many DNA molecules does this statement represent?
b. How many different types of DNA molecules does it represent?
2. DNA is extracted from cells of Neurospora, a fungus that has one set of seven chromosomes; pea, a plant that has two sets of seven chromoso
A. What is your evidence that DNA is the genetic molecule of heredity?
b. The Human Genome Project began with two goals: to know the sequence of genes on all the human chromosomes and to know the sequence of bases on all the human chromosomes. With this, individuals with genetic defects could have proper treatment.
Please explain the following questions:
1) When do strands of DNA form chromosomes?
2) What is a replicated chromosome? How does this differ from a chromosome pair?
3) Is a cell containing replicated chromosomes haploid, diploid, or neither? Why?
4) Why is anaphase unique in terms of chromosome number?
The development of DNA andgenetic analysis has opened up a whole new branch of biological investigation: molecular phylogeny. DNA analysis has been used to reclassify a great number of organisms. These ultra-sensitive techniques have been able to reveal previously imperceptible relationships between both living and extinct orga
Briefly explain of what DNA analysis is and how it can be used as evidence in criminal investigations.
Explain why extra caution must be exercised when collecting DNA analyzable evidence.
Discuss the precautions that must be followed to avoid contamination of evidence that may contain DNA evidence.
Describe the methods
Describe a single gene inherited disease, a multi-factorial (multiple genes and
environmental factors) disease, and non-inherited genetic disease. Use Down syndrome, sickle-cell anemia, asthma and breast cancer as examples
