Forensic scientists are trying to find an exact dna match to a sample left at the scene of a crime. the sample from the crime sc
aleksley [76]

The answer is ‘suspect iii has 900 bp and 260 bp sized DNA fragments’

Forensic science utilizes particular sequences of DNA that are unique to people and are cut differently by restriction enzymes. These  techniques are referred to as Restriction Fragment Length Polymorphism (RFLP) and the Short Tandem Repeat (STR) Analysis. In this case, there is an exact match on the crime sample and that of the suspect.

using the gas pedal analogy explain the impact on the cell cycle of a proto-oncogene versus an oncogene
rusak2 [61]

Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and deregulate apoptosis, while tumor suppressor would be the brakes since they constrain the progress of the cell cycle and induce cell apoptosis. An oncogene is, therefore, when the accelerator is stuck in down position and the brakes are not working.

In a certain population of fruit flies, 640 out of 1000 have red eyes, while the remainder have sepia eyes. The sepia eye trait
irga5000 [103]

Answer:

The correct answer is 160.

Explanation:

Based on the given question, the total number of fruit flies is 1000, of which red eye flies are 640. Thus, the number of sepia eye flies will be 1000-640 = 360.  

On the basis of the Hardy-Weinberg equation, p+q = 1, in which p is the rate of recurrence of one allele, that is, dominant and q is the rate of recurrence of the other allele, that is, recessive.  

q^2 for the population is 360/1000 = 0.36, q = 0.6.  

Therefore, p = 1-q = 1-0.6 = 0.4.  

The frequency of homozygous dominant allele is denoted by p^2 = 0.16.  

Hence, the number of homozygous dominant for red eye color would be 16% of 1000 which will be equal to 160.
