Show answer
Correct Option: B

Human genome project was started in

  1. $1989$

  2. $1990$

  3. $1992$

  4. $1995$

Show answer
Correct Option: B
Explanation:
The Human Genome Project was started in 1990 with the goal of sequencing and identifying all 3 billion chemical units in the human genetic instruction set, finding the genetic roots of disease and then developing treatments.

So, the correct answer is '1990'.

As per latest information human genome has

  1. $3,00,000$ genes

  2. $20,000$ genes

  3. $3,000$ genes

  4. $300$ genes

Show answer
Correct Option: B
Explanation:
There are an estimated 19,000-20,000 human protein-coding genes. The estimate of the number of human genes has been repeatedly revised down from initial predictions of 100,000 or more as genome sequence quality and gene finding methods have improved and could continue to drop further.
So, the correct answer is '20,000 genes'.

Main aim of human genome project is to

  1. Introduce new genes into human beings.

  2. Identify and sequence all the genes present in human DNA.

  3. Develop better techniques to compare two human DNAs.

  4. Remove disease causing genes from human DNA.

Show answer
Correct Option: B
Explanation:

Human genome project was a 13- year long project involving a global, long-term research effort to identify the estimated 30,000 genes in human DNA (deoxyribonucleic acid) and to figure out the sequences of almost 3 billion nucleotides that make up human DNA. It was completed in 2003.

So, the correct option is 'Identify and sequence all the genes present in human DNA.'
