the phosphate group in dna provides ______ support and stability to the dna molecule.
the four types of nitrogenous bases found in dna are adenine, thymine, cytosine, and ______.
dna strands run in opposite directions, known as ______, with one strand running from the 5’ end to the 3’ end and the other running from the 3’ end to the 5’ end.
dna is primarily housed within the ______ of eukaryotic cells, where it is folded and packaged into chromosomes.
mitochondrial dna, inherited solely from the mother, encodes genetic information essential for cellular ______ production.

Explanation:

1. The iconic double helix structure of DNA consists of how many intertwined strands?

DNA's double helix has two strands that wind around each other.

DNA nucleotides have deoxyribose as their sugar component.

The phosphate group in DNA contributes to structural support (like forming the backbone with sugar).

Answer:

2 (two)

2. Nucleotides, the building blocks of DNA, contain a sugar molecule called ______.
