Animals can be classified according to different physical characteristics, such as body covering (e.g., hair, fur, feathers, scales, shells), body shape (e.g., two main features, three main features), appendages (e.g., arms, legs, wings, fins, tails), and method of movement (e.g., walking, crawling, flying, swimming).
Answer:
B. identifying the regions of human DNA that are transcribed into RNA
C. identifying the regions of human DNA that bind to proteins
D. analyzing the regions of human DNA that vary among individuals
Explanation:
The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.
I believe your right C seems like the best choice to me.
Answer:
The correct answer is "Koch's postulates".
Explanation:
The missing options of this question are:
a) spontaneous generation
b) Koch's postulates
c) epidemiology
d) vaccination
The correct answer is option b) "Koch's postulates".
Koch's postulates propose four criteria used to establish that a pathogen is responsible for a disease. In his famous experiments, Robert Koch was able to prove that <em>Bacillus anthracis</em> is the cause of anthrax by injecting to a mouse an isolated culture from the blood of an injected sheep. The scenario established in the question is very similar to anthrax, and the scientific approach to look for the pathogen of the disease is following the principles of Koch's postulates.
