Explanation

 The special enzyme used to cut DNA at specific sequences is called a restriction enzyme or restriction endonuclease.

These enzymes are crucial for various molecular biology techniques like genetic engineering and DNA fingerprinting.

They recognize specific sequences within the DNA and cleave the molecule at those sites. 

Explanation

 The process of producing a protein from mRNA is called translation.

First, mRNA, carrying the genetic code from DNA, is created through transcription.

Then, this mRNA molecule travels to ribosomes,

Where it is translated into a specific sequence of amino acids, forming a polypeptide chain.

This polypeptide then folds into a functional protein.

Explanation

Leukemia is a cancer of the body's blood-forming tissues.

Including the bone marrow and the lymphatic system.

Some forms of leukemia are more common in children.

Explanation

The type of transpiration occurring through special openings in plant stems is called lenticular transpiration.

These openings, known as lenticels, are small pores in the bark of woody stems and allow for gas exchange and water vapor loss. 

Explanation

The yellowing of leaves due to lack of chlorophyll is called chlorosis.

This condition occurs when the green pigment, chlorophyll, is reduced or absent in the leaves, causing them to turn yellow. 

Explanation

Explanation

Chlorophyll, the pigment responsible for photosynthesis in plants, features a porphyrin ring structure at its core.

This ring is composed of four smaller pyrrole rings linked by methine bridges.

A magnesium ion is centrally located within this porphyrin ring, held in place by bonds with nitrogen atoms from the pyrrole rings.

Explanation

Chemiosmosis is the process where ATP is generated by using the energy stored in a proton gradient across a membrane.

In the context of photosynthesis, this proton gradient is established across the thylakoid membrane in the chloroplast. 

Explanation

In echinoderms, water enters the water vascular system through a sieve-like structure called the madreporite.

This structure, often a small, light-colored plate, acts as an opening to the internal water-filled canals.

Water then flows through a series of canals, including the stone canal and radial canals, eventually reaching the tube feet.

Explanation

In bryophytes, the gametophyte generation is dominant.

This means the leafy, green, haploid structure that is typically seen is the gametophyte, which is the most visible and longest-lived part of the bryophyte life cycle.

The diploid sporophyte is generally smaller and dependent on the gametophyte for survival.
