Summary Introduction

To determine:

The reason that organisms have evolved introns.

Introduction:

Introns are a sequence of nucleotides that are present with the exons in the gene and are removed during the process of RNA splicing. Gene density is the ratio of the number of genes per number of base pair. Lower organism has higher genome density as they do not have non coding (introns) sequences in their genome as compared to higher organism.

Summary Introduction

To determine:

The reason that some organisms lose introns.

Introduction:

Gene density is the ratio of the number of genes per number of base pair. Eukaryotic organisms have introns in their genome and contain higher number of genes. Thus, they have lower gene density as compared to prokaryotes.

Most people, even those who exercise regularly at low to average intensity (1 hour at the gym or a 2- to 3-mile walk several times per week), do not need an increased protein intake. What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb.   Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place. Because protein requirement is a range, please enter two numbers: lower and upper range values, respectively.   Separate the lower and upper range values, in that order, by a comma.   ___, ___ g ?
