DNA Structure & Nucleotides
DNA is a polymer made from four different nucleotides, forming a unique double-helix structure.
Which base always pairs with Cytosine?
What is DNA Structure & Nucleotides?
"DNA structure refers to the double-helix arrangement of two strands of nucleotides, where bases are linked by hydrogen bonds."
How many times does the cell divide during meiosis?
Why is understanding the human genome important for modern medicine?
Which group belongs to the domain Archaea rather than true bacteria?
If both parents are heterozygous (Bb) for a recessive trait (b), what is the probability their child will express the trait?
Molecular Structure
Each nucleotide consists of a sugar, a phosphate group and one of four bases (A, C, G, T).
The code is determined by the sequence of these bases.
In a complementary strand, C always pairs with G, and T always pairs with A.
Three bases in a row code for a specific amino acid; these amino acids join to form a specific protein.
