Which statement about the human genome is false?
Human genome encompasses all set of nucleic acid sequences of humans that are encoded as DNA. Statement D is false since not all nucleotide sequences code for protein as some long stretches of DNA can have no known function.
What is the correct order of the genome?
From the above explanation it is clear that the series of organisation of genetic material from largest to smallest is Genome, Chromosome, Gene, Nucleotide which is given in the option D. Thus, the correct answer is option D i.e., Genome, Chromosome, Gene, Nucleotide.
Which is the correct definition of a genome?
A genome is the complete set of genetic information in an organism. It provides all of the information the organism requires to function. In living organisms, the genome is stored in long molecules of DNA called chromosomes.
What does the human genome contain?
The diploid human genome is thus composed of 46 DNA molecules of 24 distinct types. Because human chromosomes exist in pairs that are almost identical, only 3 billion nucleotide pairs (the haploid genome) need to be sequenced to gain complete information concerning a representative human genome.
How much of the human genome is understood?
The human genome contains around 20,000 genes, that is, the stretches of DNA that encode proteins. But these genes account for only about 1.2 percent of the total genome. The other 98.8 percent is known as noncoding DNA.
Which of the following is incorrect regarding genes?
Answer: incorrect option is option (ii). Explanation: chromosome carry genes from one generation to other generation.
When was the human genome decoded?
1999. In December 1999, an international team of researchers achieves the scientific milestone of unraveling the genetic code of an entire human chromosome for the first time. Researchers decipher the sequence of the 33.5 million letters that make up the DNA of chromosome 22.
What did human genome project do?
The Human Genome Project (HGP) was an international 13-year effort, 1990 to 2003. Primary goals were to discover the complete set of human genes and make them accessible for further biological study, and determine the complete sequence of DNA bases in the human genome.
What statement best describes a human chromosome?
Which statement best describes a human chromosome? It contains genes that may code for the production of enzymes. The diagram below represents a structure found in most cells.
Which of the following is the correct sequence of units of genetics?
Gene →Recon → Cistron →Muton.
