Human dna strand
WebDNA consists of nucleotides, think of it as a letter code (the letters are A, T, G and C). Certain sequences of these letters are used to define certain features (for example, ATG denotes the start of the gene), with 3 letters called a codon, which codes for a … Web16 Feb 2024 · The sequence of four bases along the DNA strand encodes the genetic information as genes. The size of the human genome is 3.2 billion base pairs. Humans have about 21,000 of genes. More than 98% of human DNA is composed of non-coding sequences whereas the other sequences are encoded for proteins.
