Which of the following provides fund for the human genome project?

  1. NIH

  2. DOE

  3. Both A and B

  4. NIH, DOE and ELSI
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Human Genome Project was started by US department of energy and National Institute of Health and this was done for the sequencing of human genome.

It was approximately quoted to be around 9 billion US dollars.
So, the correct option is 'Both A and B'

Human genome project was

discovered by

  1. Francis Collins and Roderick

  2. Watson and Crick

  3. Beadle and Tatum

  4. Paul Berg and Wollman

A Correct answer
Explanation

The Human Genome Project was led by Francis Collins (director of the National Human Genome Research Institute) and Craig Venter (founder of Celera Genomics), not Watson and Crick who discovered DNA structure decades earlier. The question likely refers to this leadership.

Human genome project was launched in

  1. 1980

  2. 1987

  3. 1990

  4. 1993
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Human Genome Project was launched in 1990 by coordination of US Department of Energy and National Institute of Health. The 13-year mega project was aimed to sequence complete 3 billion DNA base pairs that make up human genome. So, the correct answer is ' 1990'.

Human genome contains base pairs

  1. 2.5 million

  2. 25 million

  3. 27.2 million

  4. 3.2 billion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

There are four bases adenine (A), thymine (T), guanine (G) and cytosine (C) present in humans. Bases on opposite strands pair specifically as an A always pairs with a T, and a C always with a G. The human genome contains approximately 3.2 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells.

So, the correct option is '3.2 billion'.

Number of genes present in human genome is about

  1. 15,000

  2. 21,000

  3. 27,000

  4. 30,000
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
A gene is a distinct sequence of nucleotides forming part of a chromosome.
Most of the genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project estimated that humans have around 21,000 genes.
So, the correct option is '21,000'.

A ribotide is made of

  1. Adenine + Deoxyribose + Phosphate

  2. Uracil + Ribose + Phosphate

  3. Thymine + Ribose + Phosphate

  4. Uracil + Deoxyribose + Phosphate
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A ribotide (ribonucleotide) consists of a nitrogenous base (like Uracil in RNA), a ribose sugar, and a phosphate group. Deoxyribose is found in DNA, not RNA.

Which ones are degenerate codons ?

  1. UAA, UAG and UGA

  2. GUA, GUG, GCA, GCG and GAA

  3. UUC, UUG, CCU, CAA and CUA

  4. UUA, UUG, CUU, CUC, CUA and CUG

  5. AAC, AAG, GAC and CGG
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Degeneracy means that multiple codons can code for the same amino acid. The set UUA, UUG, CUU, CUC, CUA, and CUG all code for the amino acid Leucine.
