DNA fingerprinting
footprinting
Telomeres are made of repetitive DNA sequences and associated proteins. The DNA part typically consists of a repeating sequence like TTAGGG in vertebrates. These structures cap the ends of chromosomes, protecting them from degradation and maintaining chromosomal stability.
genes
Amino acids
All of the different proteins in a cell are made from the same 20 amino acids. These amino acids are encoded by the genetic information in DNA and are linked together in specific sequences to form different proteins with unique structures and functions. The diversity of proteins in a cell arises from the different sequences and arrangements of these 20 amino acids.
Repeated DNA sequences that do not code for proteins can be used for a variety of purposes, such as regulating gene expression, building centromeres and telomeres, and playing a role in genetic recombination and chromosomal structure. They can also be used as genetic markers for mapping and identifying specific regions of the genome.

Sequences of nitrogenous bases in the cell's DNA.
Sequences of nitrogenous bases in RNA that do not code for proteins are called non-coding RNAs. These non-coding sequences play various regulatory roles in the cell, such as gene expression regulation and cellular processes modulation.

The diversity of proteins in a cell arises from the different sequences and arrangements of these 20 amino acids.
The variation in amino acid sequences can impact the functionality and characteristics of different organisms by affecting the structure and function of proteins. Changes in amino acid sequences can alter the shape and activity of proteins, leading to differences in biological processes and traits among organisms.
The genetic code is the set of rules by which information encoded in genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells.
