Differentiate between fibrous proteins and globular proteins. What is meant by the denaturation of a protein?

(c) DNA and protein

Hypocotyl Epicotyl The portion of the embryonal axis which lies below the cotyledon in a dicot embryo is known as the hypocotyl. The portion of the embryonal axis which lies above the cotyledon...

Dominance Recessive A dominant factor or allele expresses itself in the presence or absence of a recessive trait. A recessive trait is able to express itself only in the absence of a dominant...

Many proteins including certain toxins are secreted in their inactive form. They get activated, only when exposed to a specific trigger (pH. temperature etc.). It is advantageous to the bacteria...

If denaturation of double-stranded DNA does not take place, then primers will not be able to anneal to the template, no extension will take place, hence no amplification will occur.

Proteins found in a biological system with unique 3D-structure and biological activity is called native protein. When native protein is subjected to physical and chemical change, protein loses its biological activity...

(i) Peptide linkage : A link between two amino acids with loss of water /- CO - NH - peptide linkage. (ii) A process that changes the three dimensional structure of native protein is...

(i) Pollination : The transfer of pollen grains from the anther to the stigma is called pollination. The two types of pollination : (a) Self pollination : When the pollen grains from...

Fibrous Proteins Globular Proteins 1. Consist of linear thread-like molecules which tend to lie side by side to form fibre like structure. 1. Polypeptide chain  s folded, around itself forming almost spheroidal shape. 2. Insoluble...

d. They can act both as activators and as repressors
