|Term Which of the following processes can be the result of human manipulation of microbial genes||Definition Bioremediation|
Which of the following is a macromolecule that assembles into bilayers?
Phospholipids have a hydrophobic tail, but a hydrophilic head. Self- assembles into micells or bilayers, an important part of cell membranes.
Which organisms has the best potential to survive in extreme environments?
Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.
How are bacteria used in genetic engineering quizlet?
How are bacteria used in genetic engineering? the bacteria is used to inject or make protein in the organism. DNA transfers through sexual reproduction requiring meiosis and asexual reproduction requiring mitosis equip organisms in different ways for survival.
What are the four major types of microbes?
The major groups of microorganisms —namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below.
What are the methods or techniques used in manipulating DNA?
Basic techniques used in genetic material manipulation include extraction, gel electrophoresis, PCR, and blotting methods.
What is the CHO ratio in proteins?
1:2:1 Lipids 1:2:very few Proteins There is no reliable C:H:O. ratio for proteins. What is the approximate Cho ratio in proteins?
|Carbohydrates||organic molecules composed of carbon, hydrogen, and oxygen in a ratio of 2-hydrogen atoms to every 1 oxygen atom.|
What are four types of macromolecules found in living things?
The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
Which atoms are in all carbohydrates?
Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements.
What organisms are found in extreme environments?
Extremophiles are organisms that live in ” extreme environments,” under high pressure and temperature. Bacteria often form on the rocks near the hydrothermal vents.
What are 5 of the most extreme conditions that bacteria can live?
Extremophiles are organisms that have been discovered on Earth that survive in environments that were once thought not to be able to sustain life. These extreme environments include intense heat, highly acidic environments, extreme pressure and extreme cold.
Is life possible in extreme conditions?
Scientists have found life in every extreme environment you can imagine, from volcanic cauldrons to highly alkaline seas. These extremophiles are not just curiosities; they could show us how life might exist on other planets with more hostile conditions than Earth.
What role does bacteria play in genetic engineering?
Genetic engineering is the transfer of DNA from one organism to another using biotechnology. Bacterial cells can be genetically modified so that they have the gene for producing human insulin. As these modified bacteria grow, they produce human insulin. This protein can be purified and supplied to diabetics.
How is a gene cloned?
In a typical cloning experiment, a target gene is inserted into a circular piece of DNA called a plasmid. The plasmid is introduced into bacteria via a process called transformation, and bacteria carrying the plasmid are selected using antibiotics.
What are two applications of transgenic organisms?
Transgenic organisms have also been developed for commercial purposes. Perhaps the most famous examples are food crops like soy and corn that have been genetically modified for pest and herbicide resistance. These crops are widely known as “GMOs” ( genetically modified organisms ).
