The enzyme DNA ligase can be defined as the DNA joining enzyme. The DNA ligase joins smaller strands of the DNA making them into one continuous strand. The DNA ligase is responsible for the joining of the okazaki segments, and the repairs in the backbone of the DNA strands. If the levels of the DNA ligase will decrease in a person's body because of a mutation, it will be difficult to repair the DNA and join the okazaki segments and hence, the gene expression will be altered. The packaging of the DNA will be altered too, and the DNA will be present in a person's body in fragments. Hence, the DNA replication will lead to the formation of the multiple small fragments.

DNA ligase is the enzyme that repair irregularities and breaks in the back bone of double stranded DNA. The enzyme function by sealing the repair in the DNA, it seals recombination fragments and it connects okazaki fragments during replication of DNA.
If a mutation reduce the amount of ligase, all the functions of the ligase enzyme listed above will be affected negatively.

What is the difference between a vascular and a nonvascular plant? In your answer, discuss how water moves in each type of plant

dexar [7]

Both plants have separate tubular tissues like Xylem and Phloem to transport food, minerals, and water, right? Those are called the vascular plants. So for those that don't show this kind of differentiation of the tissue, they're called the non-vascular plants.

Water and the other nutrients just move through the plants' body, cell by cell. The plants can get water this way but only if the plants' body is no more than a few cells thick.

fiber - carbohydrate that slows the absorption of sugars into the bloodstream

calcium - mineral found in every cell of the body and is involved in the formation of teeth

phosphorous - mineral involved in the process through which muscles contract and relax

cholesterol - lipid molecule produced by all cells in the body and that forms lipoproteins

cluponka [151]

A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound.
