Answer:
The number of STR repeats is unique and therefore it is considered as an allele of that <em>locus</em>
Explanation:
Short Tandem Repeats (STRs), also known as microsatellites or simple sequence repeats (SSRs), are short DNA sequences with a size of 1-6 nucleotide bases which may be many times repeated in tandem. STRs localize in specific regions of the genome (<em>loci</em>) and therefore they are molecular markers. Gel electrophoresis a technique used to separate DNA fragments based on their size. In consequence, the pattern of STR repeats or 'alleles' obtained by electrophoresis can be used to identify individuals. In a gel electrophoresis, STR markers produce different bands that run more slowly or faster on the gel in different lanes according to their size (e.g., more slowly >> higher size of the STR sequence), and thereby STR alleles are unique and serve to identify individuals.
In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. ... Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.
Answer:
El efecto del material sobre el medio ambiente es el aspecto a considerar.
Explicación:
Se debe verificar la estructura química del material o de qué elementos se forma un material para conocer el efecto de estos materiales en la salud y el medio ambiente de las personas. Si los materiales no afectan el medio ambiente y la salud humana, el ser humano puede utilizarlos para satisfacer sus necesidades. Si el material se forma a partir de elementos tóxicos o elementos que no se descomponen por microbios, entonces este tipo de materiales son peligrosos tanto para la salud humana como para el medio ambiente porque estos materiales contaminan el medio ambiente y debido a esta contaminación la salud humana se ve gravemente afectada.
Mendel observed that a heterozygote offspring can show the same phenotype as the parent homozygote, so he concluded that there were some traits that dominated over other inherited traits. However, the relationship of genotype to phenotype is rarely as simple as the dominant and recessive patterns described by Mendel.
