Description : How can a DNA microsatellite be co-dominant if microsatellites are Short Tandem Repeats which in turn are typically non-coding?
Last Answer : answer:Any DNA that does not code directly for the sequence of amino acids in a protein is non-coding or junk DNA. However it is important to realise that just becaue the DNA does not code for a ... thought to have a role in gene expression. ie when and how a gene is used to make a protien.

Description : The smallest unit of DNA capable of coding for the synthesis of a polypeptide is (A) Operon (B) Repressor gene (C) Cistron (D) Replicon
Description : The process of producing a protein from its DNA- and mRNA-coding sequences.
Last Answer : Ans. Gene expression
Description : The coding segment of DNA is called in (1) Codon (2) Muton (3) Intron (4) Exon
Last Answer : (1) Codon Explanation: The genetic code by which DNA stores the genetic information consists of "codons" of three nucleotides. The functional segments of DNA which code for the transfer of ... information are called genes. A colon is defined by the initial nucleotide from which translation starts.
