explain why it is important to keep the levels of nucleotides relatively balanced in the context of dna and rna synthesis
juin [17]

Answer:

Read Below

Explanation:

Nucleotides are A & T and G&C you see in DNA and in RNA T is Replaced by U. The reason they must be balanced between G&C and T&A is because G has to bond with A in DNA and G with C so if there is more G than C that means there is mismatches between the DNA nucleotides same thing for A and T. In RNA you follow the same rule. If we have lets say 27% of our DNA as A we have to have 27% as T leaving 23% as C and 23% as G. If there was lets say 29% T while one 27% A then there was a error in DNA replication and could lead to errors in RNA synthesis if not corrected

Describe the two different notations used to specify isotopes and give an example of each.
Georgia [21]
There are two ways that can be used to name isotopes of an element. This is best illustrated by examples. We'll use the element chlorine for simplicity.

The first example is the more common one. The formula for this notation is E-m where E is the name of the element and m is the mass number. 
(1) Chlorine-35
(2) Chlorine-37
(3) Chlorine 38

Another is less commonly used. The formula for this notation is m^ a L where m is the mass number, a is the atomic number and L is the first letter of the element.
(1) 35^ 35 Cl
(2) 37^ 35 Cl
(3) 38^ 35 Cl
