What are some challenges in extracting dna from samples related to an active investigation?

Answers

Answer 1

Answer:

Explanation:

"The problem with DNA is that it is perceived as providing a unique and infallible ID," . "But very often there are disagreements among experts about whether results are a match." Reasonable doubt? In the glitzy labs of crime dramas, no one argues about whether the DNA is a match.

Answer 2

There are various challenges in extracting DNA from samples related to an active investigation. Some of the challenges are the following:

1. Many DNA's touch evidence samples are poor-quality, low-template, and complex mixtures

2. Various laboratories are not capable to cope with the DNA complex mixtures

3.  The suspect's DNA may have been at the crime scene before the scene occurs.

4.  Just because DNA proves a suspect to be at the crime scene doesn't mean the suspect is the culprit.

5. Additional loci are being added due to a large number of samples in DNA databases.

At what point in the pregnancy is the fetus’ brain fully developed?.

Answers

Answer:

At just six weeks, the embryo's brain and nervous system begin to develop, although the complex parts of the brain continue to grow and develop through the end of pregnancy, with development ending around the age of 25.

Explanation:

The brain begins with the neural tube, formed in the first month of the embryo’s growth. The neural tube closes around week 6 or 7, at which point the brain separates into three parts: front brain, midbrain, and hindbrain. These three parts will eventually develop into the specialized parts of the brain, and the cerebrum will fold into the left and right halves of the brain.

From the time the neural tube closes, around week 7, the brain will grow at a rate of 250,000 neurons per minute for the next 21 weeks. Ultrasounds can reveal the embryo moving as early as 6 weeks after conception (or 8 pregnancy weeks), detecting the electrical impulses that govern movement and indicating that the brain is beginning to function.
