Citrus2011 [14]

Answer: The genetic content in non-homologous chromosomes would be different.

Explanation:

Homologous chromosomes have the same length, share the same position of centromere and the same types and location of genes. If two chromosomes of a species are the same length and have similar centromere placements and yet are not homologous, the genetic content would be different.

Damm [24]

Given: The systolic arterial blood pressure observed for 20 dogs is normally distributed with a mean of 152 mm of mercury (Hg) and a standard deviation of 18 mm of Hg.  

To find: P(100 < 152)

Method: Calculation of Z-Score followed by the probability or area of the bell curve at X = 100.

Solution:

Mean u = 152, std s = 18

Z score = \frac{X-u}{s} = \frac{100-152}{18} = -2.89

The value of P(100<152) is calculated by looking at the value of Z in the Z score for the standard normal distribution given in the image.

P(Z=-2.89) = 0.0019

The P(Z = -2.89) corresponds to the area in the left tail of the bell curve.

Thus the probability of 100 mm Hg blood pressure is 0.0019.

2. Genetic code is the nucleotide sequence of a gene while the gene expression is how these sequences are used to make functioning amino acids and proteins to create DNA.

3. In each cell itself there are roughly 42 million proteins.
