Answer:
The correct answer is - option e.)
Explanation:
The experiment that was performed by Meselson and Stahl was created to prove that DNA replication is a semiconservative process.
When Bacteria grow on 15N media they incorporate the isotype of nitrogen and after few generations, the culture moved to 14N media where it incorporates as they replicate in semi-conservative mode and one DNA strand comes from the Parent DNA.
The right option for question one is Option (e) Run as one band, at a position expected for DNA containing a 14N:15N ratio equal to 1.
Answer:
Chemical Energy
Explanation:
Chemical energy is simply energy that is stored in compounds or elements, specifically in the atomic bonds that connect atoms and molecules. In food, it's a form of potential energy because it's stored away.
I found this info if this is what you need link http://www.answers.com/Q/What_are_the_functional_groups_of_amino_acids
Two functional groups are found in all amino acids. These functional groups are the
amino group
(-NH2) and the
carboxyl group
(-COOH). The hydrogen atom of the carboxyl group can be broken off quite easily; this gives amino acids their acidic properties.
Function of amino acids?
Heat and Energy, Growth, To defend against disease, and to Repair bodily cells are the functions of amino acids/ proteins.
Amino acids contain a carboxyl group?
Yes, amino acids contain: 1) an amino group (-NH 2 ) 2) a central carbon and variable side group 3) a carboxyl group (-COOH)
What is the function of amino acids?
Amino acids are nitrogen-containing molecules that serve vitalfunctions in your body. Twenty-two amino acids occur in nature, and20 of these are incorporated into proteins and other moleculeswithin the cells and tissues of plants and animals. According toscientists at the University of Arizona, your body can synthesize10 of the amino acids you need, while the other 10 must be acquiredfrom your diet. Amino acids that cannot be produced within yourcells are called essential amino acids. http://www.livestrong.com/article/426255-what-is-the-function-of-amino-acids-in-the-human-body/
What is the amino group on an amino acid?
The amino group is present at one end of the amino acid and is represented by the chemical formula NH 3 The region on the amino acid that contains the amino group is called the amino terminal
Amino acid function?
Amino acids are basically known as the building blocks of protein.The function of an amino acid is primarily to build proteins.
In a DNA molecule, three nucleotides make up a codon. A codon is creates a specific amino acid. Therefore, in order to work this out, we must calculate the number of codons that will not be affected by the mutation. This is done by finding the highest number that is divisible by 3 but less than 85. This can be done by:
85 / 3 = 28.333
So 28 codons will not be affected.
