Homeobox genes are a large family of similar genes that direct the formation of many body structures during early embryonic development. In humans, the homeobox gene family contains an estimated 235 functional genes and 65 pseudogenes (structurally similar genes that do not provide instructions for making proteins).
Palindromes. A palindrome is a sequence of letters and/or words, that reads the same forwards and backwards.  able was I ere I saw elba  is a palindrome. Palindromes also occur in DNA.There are two types.. Palindromes that occur on opposite strands of the same section of DNA helix. 5' GGCC 3' 3' CCGG 5'. This type of palindrome serves as the target for most restriction enzymes. The graphic shows the palindromic sequences seen by five restriction enzymes (named in blue) commonly used in recombinant DNA work.
A DNA profile is a string of numbers based on parts of a personâs DNA. Short strings of the chemical letters that make up a personâs DNA occur repeatedly in parts of the genome. These are known as short tandem repeats (STRs).The number of repeats differs between individuals and can be counted. DNA profile is a string of numbers based on parts of a personâs DNA.
