WebDNA is made of four types of nucleotides, which are linked covalently into a polynucleotide chain (a DNA strand) with a sugar-phosphate backbone from which the bases (A, C, G, and T) extend. The sugar-phosphate form the backbone of DNA helix and is the outside, interconnected by the complementary base pairs like rungs of a ladder.

WebRole of primers in PCR: The DNA fragments which are to be amplified are determined by selecting primers. Two primers are used, which determine the beginning and end regions that are to be amplified. Primers are artificial, short DNA strands having 18-25 base pairs, having not more than 50 nucleotides that are complementary to the end and ... WebIts function is to encode at least one gene. Suppose if gene encodes protein than mRNA is produced by transcription. A protein encoded by the DNA transcription unit may comprise a coding sequence. Compared to …
WebThe nucleolus is the distinct structure present in the nucleus of eukaryotic cells. Primarily, it participates in assembling the ribosomes, alteration of transfer RNA and sensing cellular stress. The nucleolus is composed of RNA and proteins, which form around specific chromosomal regions. It is one of the main components of the nucleus. WebCodon: A codon is the triplet of a set of bases (or nucleotides) in DNA that codes for an amino acid. The triple base complement for a codon is called an anticodon; By convention, triplets in mRNA are called codons, and triplets in tRNA are called anticodons. These codons are translated into protein sequences.
WebThe important ribosome function includes: It assembles amino acids to form proteins that are essential to carry out cellular functions. The DNA produces mRNA by the process of DNA transcription. The mRNA is … WebDNA is an organic, complex, molecular structure found in both prokaryotic and eukaryotic cells and also in many viruses. It is a hereditary material which is found in the nucleus of the cell and is mainly involved in carrying genetic information. The DNA structure has the following characteristics:
WebChromosome. Chromosomes are the genetic material present in all cells. They are present in the nucleus of a eukaryotic cell. They are a thread-like structure.
