Consider an animal. During DNA replication, all base pairs of DNA are copied. But, during transcription, only some of the DNA bases are transcribed. What parts of the DNA or/and protein(s) det
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
Consider an animal. During
Introduction:
DNA (Deoxyribonucleic acid) is a long, double-stranded molecule that carries the genetic information for all living organisms. DNA is composed of four basic building blocks, called nucleotides, which are adenine (A), cytosine (C), guanine (G), and thymine (T). The order of these nucleotides in the DNA molecule determines the genetic code, which provides instructions for the development and function of cells. The two strands of DNA are held together by weak hydrogen bonds between the complementary nucleotides, forming the famous double-helix structure. DNA replication is the process by which cells make a copy of their DNA in preparation for cell division, and DNA transcription is the process by which the information stored in DNA is used to synthesize RNA, which carries the genetic information to ribosomes for protein synthesis.
