Since there are 64 triplet codons and only 20 amino acids, genetic code is non-ambiguous. Non-ambiguous code means that there is no ambiguity about a particular code. One codon specifies only one amino acid and not any other except GUG which normally codes for valine but in certain conditions it also codes for N-formyl methionine as initiation codon.

Repeated or repetitive sequences make up large portion of human genome. Repetitive sequences are nucleotide sequences that are repeated many times, sometimes hundred to thousand times. They have no direct coding function but provide information as to chromosome structure, dynamics and evolution. Approximately 1 million copies of short 5-8 base pair repeated sequences are clustered around centromeres and near the ends of chromosomes. They represent junk DNA. 

All living organisms—present, past and future are linked to one another by the sharing of the common genetic material, but to varying degrees.

The human genome consists of 50,000 to 100,000 genes located on 23 pairs of chromosomes. One chromosome in each pair is inherited from the mother, the other from the father. Each chromosome contains a long molecule of DNA, the chemical of which genes are made. 

The human genome consists of 50,000 to 100,000 genes located on 23 pairs of chromosomes. One chromosome in each pair is inherited from the mother, the other from the father. Each chromosome contains a long molecule of DNA, the chemical of which genes are made. Genes are of differing length, ranging in size from roughly 2,000 to as many as 2,000,000 base pairs. 

Human genome has around 21,000 genes in its 3.3 billion base pairs haploid genome. The haploid DNA content of a cell is called as C-value. The C-value paradox is concerned with presence of excessive amounts of DNA in eukaryotic cells and the difference of C-value between eukaryotic species having similar complexity. Presence of large amount of base pairs is explained on the basis of large amount of structural DNA and junk DNA in chromosomes. Thus, correct answer is '3.3 billion'.

Human Genome Project was a 13-year-old project started by US department of energy and National Institute of Health for sequencing the Human Genome.

The main aim of the Human Genome Project was to determine the sequence of 3.2 billion base pairs of Human Genome and to identify their functions.

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.

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'.

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.

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.

A process in which amniotic fluid is sampled using a hollow needle inserted into the uterus, to screen for abnormalities in the developing fetus.

The sequencing of the entire genome of an organism was completed in 1996 and the organism was yeast.

The Human Genome Project (HGP) is an international scientific research project with the goal of determining the sequence of chemical base pairs which make up human DNA and of identifying and mapping all of the genes of the human genome from both a physical and functional standpoint. It remains the world's largest collaborative biological project. The project was proposed and funded by the US government; planning started in 1984, the project got underway in 1990 and was declared complete in 2003. The project has been organized and supported primarily by the DOE, European Commission and the NIH, which established working groups to address genome mapping, computational analysis to handle databases, and the social, legal, and ethical implications of the human genome research. Congress funds the project through the National Centre for Human Genome Research at the NIH, which in turn awards grants and contracts to U.S. investigators. Additional funding from Congress goes to the DOE, which conducts research on human genetics at three national laboratories and also funds independent or private investigators.
