Question

3. In 1999 , a massive research effort was started to identify all of the genes in the

human genome.
2. Why would having the human genome be helpful?
because it is known to keep away bad spirits.
are common to all people, but slight variations between genes in different
people make each person
4. By looking at the gels from an individual's DNA, scientists realized that each person in
the world (except for identical twins) had a _ _DNA "fingerprint" due to
repeated segments. This could be used to identify family relationships or identification in
criminal cases.
5. Scientists knew that DNA was made up of just four basic units, known by their initials,

Answer 1

2. Having the human genome be helpful because gene are common to all people.

4. By looking at the gels from an individual's DNA, scientists realized that each person in the world (except for identical twins) had a different DNA sequence due to repeated segments.

Step-by-step explanation:

2. The Human Genome Project is helpful because:

Sequencing of all the genes in human are done so it makes the diagnosis easy. The functions of the gene is known this way. The disease causing genes could be easily studied and alteration and mutations could be fixed by gene therapy.

The 3 billion base pairs are sequenced to know various details like dissimilarities in the base pairs of different organisms.

4. There are 3 million locations in the genome of human where single DNA base pair difference occur in human.

The repetitive sequences are studied and their quantity is known and their usefulness in the body. SNP (single nucleotide polymorphism) are the genetic variation of individuals.

It is found that genome sequences of organism is different only by 0.2% which helps in DNA fingerprinting.
