A three banded isoenzyme pattern with a 1:2:1 intensity ratio indicates a ________________ protein.
djverab [1.8K]

A three banded isoenzyme pattern with a 1:2:1 intensity ratio indicates a <u>dimeric</u> protein.

  • Isozyme is a multimeric forms of enzyme having similar specificity of the substrate but differences in kinetics and molecular weights of the enzymes.
  • The banding patterns of isozyme observed from electrophoresis is related to the genetic conditions in which different combination of polypeptide chains exhibited under the mendelian principles.
  • Hence with the intensity of 1:2:1 ratio, three banded phenotypes are formed having two homomeric and one heteromeric form from the dimeric protein in both multiple alleles at single loci and multiple /single allele at multiple loci.

lawyer [7]

The correct options are, frying an egg and burning candle.

Physical change : It is a change in which no new compounds are formed only changes occurs in size or state of substance. In this, there is no changes in the substance or compound.

Chemical change : It is a change in which a new compounds are formed by the chemical reaction. Changes occurs in their chemical composition and properties.

Frying an egg : It is a chemical change because a new substance is form by heating.

Burning a candle : It is chemical change because new substances are formed (carbon dioxide, water and heat) by burning.

Boiling alcohol : It is physical change because only changes in the state.

Melting and ice : It is a physical change because only changes in the state.

Making coffee : It is a physical change because no new substance is formed.

Therefore, frying an egg and burning candle are the example of chemical change.

What is the relationship between seive cells and companion cells in phloem tissue?
STALIN [3.7K]
 Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasnodesmata (channels between the cells). Each companion cell is derived from the same mother cell as its associated sieve tube member. Sieve tube members have no cell nucleus, ribosomes, or vacues. Thus, they depend on companion cells to provide proteins, ATP, and signalling molecules
