3 billion
There are three nucleotide Bases for each codon, so the Answer is 72 bases.
There are four nitrogen bases in DNA nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). Each nucleotide contains one of these nitrogen bases.
You have A (adenine),C (cytosine) ,G(guanine) and either T(thymine) or U(uracil)
4. adenine,thymine, guanine ,cytosine
I'm not fully sure of your question, but if you are asking how many nucleotide bases are needed, then the answer is 3. Three nucleotide bases of DNA will translate to mRNA and these will code for tRNA anticodons, which carry one amino acid with them.
There are about 6 feet of DNA in each human cell, which is tightly packed into the cell's nucleus. The DNA molecule is incredibly long and thin, but can fit into a single cell by being tightly coiled and wrapped around proteins called histones.
4. adenine,thymine, guanine ,cytosine
3.4 billion
6.4 x 10^9
The human genome consists of about 3.2 billion nucleotide base pairs, which are the building blocks of DNA. This means that there are approximately 6.4 billion individual nucleotides in a human diploid cell, as each cell has two sets of chromosomes.
3 nitrogenous bases form one "word" of a mRNA's message.
There are four DNA nucleotides, each with one of the four nitrogen bases (adenine, thymine, cytosine, and guanine). The first letter of each of these four bases is often used to symbolize the respective nucleotide (A for adenine nucleotide, for example). In RNA the bases are the same except that when pairing of bases occurs in RNA, uracil (instead of thymine) pairs with adenine.
