Answer:
C. Is a repeated sequence of DNA in a non- coding sequence
D. Can be composed of a variable number of repeats in different people
Explanation:
Short Tandem Repeats (STRs) are short DNA motifs, i.e., short nucleotide repeat units (generally 2-7 base pairs in size) that may have a different number of repeats among individuals (alleles). Polymorphic STR sequences are very useful genetic markers and therefore they are used for different purposes, e.g., for constructing genome linkage maps, identification of individuals and/or populations, paternity testing, etc. For example, in the USA, the Combined DNA Index System (CODIS) is a databank that stores different DNA profiles based on 13 core STR <em>loci</em> which are used in forensic identity testing.

<span>During meiosis, homologous chromosomes can exchange DNA in a process known as : Crossing over
Crossing over is one of the final phase of genetic recombination, which happen in Meiosis during a process called Synapsis. It occurs when matching part of matching chromosomes broke and reconnect with other chromosomes
