Question
Which of the following is NOT an accurate characterization of what a gene is?
each DNA molecule in one of your cells is one gene
a gene is a sequence of nucleotides, hundreds or thousands of nucleotides long
the gene is the basic unit of biological heredity
a gene is a nucleotide sequence that encodes a protein
genes are units of instructions for building and maintaining an organism
each DNA molecule in one of your cells is one gene
a gene is a sequence of nucleotides, hundreds or thousands of nucleotides long
the gene is the basic unit of biological heredity
a gene is a nucleotide sequence that encodes a protein
genes are units of instructions for building and maintaining an organism
Explanation / Answer
DNA is a long polymer of nucleotides arranged in a particular sequence. It carries the instructions for the genetic makeup of an organism. DNA transcribes into mRNA and translates into proteins which derive the structural and fucntional basis of a living cells. but the whole DNA is not used to synthesize proteins. DNA consists of specific sequences which are meaningful and carry information of a protein. Rest DNA is just a repeatitive sequence of nucleotides.
These specific sequences in the DNA which finally translates into protein are called GENES. They are hundreds or thousands of nucleotides long. They are the basic unit of hereditary.
A cell contains one polynucleotide as DNA but DNA has many genes. so one cell cannot have one gene.
thereofre the correct answer is option A- each DNA molecule in one of your cells is one gene. This statement is false.
