the answer is four (4) billion pairs
3 billion
the human genome
A DNA molecule consists of two strands that are connected by hydrogen bonds between complementary bases. Each strand has a backbone made up of alternating sugar and phosphate groups, with bases extending inward. The number of rungs in a DNA molecule depends on the length of the molecule, with each base pair forming one "rung."
Human DNA contains 3 billion pairs of nitrogen bases, which means that it contains a total of 6 billion nitrogen bases, and 6 billion DNA nucleotides, which are the monomers of DNA. Each nucleotide contains one nitrogen base.
which human activity is correctly paired with its likely future consequence
They are paired. Males have XY as a pair and females have XX as pairs.
The number of nucleotides in a DNA sequence can vary, but in general, a human DNA molecule contains about 3 billion nucleotides.
their are 4
One human cell typically contains a double-stranded DNA molecule with around 6 billion base pairs. This DNA is organized into 23 pairs of chromosomes located in the cell nucleus. Each base pair consists of two nucleotides that form the building blocks of DNA, namely adenine, thymine, cytosine, and guanine.
The Human Genome Project was created to count or analyze the sequence of human DNA. The study counted the base pairs that make up the human genome and studied the sequence and position of the nucleotide bases that make up the DNA molecule.
There are approximately 3.2 billion base pairs in the human genome. Base pairs incorporate two DNA molecules, leading to about 6.4 billion bases (1:1 ratio between nucleobases and DNA, since nucleobases are part of DNA). Since most cells contain the whole genome (T-Cells do not, but...), we can estimate 6.4 billion bases * about 10^14 (rough amount of cells in a human), giving 6.4e24 (6.4 * 10^24) DNA molecules. This is a very rough estimate.
Humans have paired salivary glands.
