An answer might be - Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

List the 3 stages of cellular respiration.

Contact [7]

The three main stages of cellular respiration (aerobic) would include Glycolysis, the Kreb's Cycle and the Electron Transport Chain. The Krebs Cycle takes Citric Acid which is a derivative of Pyruvic Acid and converts this through 4 cycles into Hydrogen, carbon dioxide and water in the Mitochondrial Matrix.

The crispr system involves the cas9 enzyme, which identifies specific nucleotides to be cut using a(n) ________ molecule as a gu

bonufazy [111]

Answer:

RNA

Explanation:

CRISPR system was discovered by a Japanese scientist. Naturally bacteria and many other prokaryotes have CRISPR system in their genome which they use as a self defense against a pathogen which is invading them. It consists of inter spaced, short palindromic nucleotide repeats which encode a guide RNA (gRNA). This guide RNA (gRNA) recognizes the target sequence on the pathogen. The gRNA is followed by Cas9 enzyme which along with the gRNA plays a very important role in breaking genome of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by non homologous end joining.

But nowadays, scientists are using this system for genome editing and incorporating desired gene between the two ends which are cut down by CRISPR Cas9 system.

What does a restriction enzyme create that allows a gene to bond to a plasmid?

antoniya [11.8K]

Answer:

D. Ligase

Explanation:

Ligase is an enzyme that can catalyze the fusion of two large molecules through the formation of a new chemical bond, which is usually accompanied by the hydrolysis of a small end chemical group.

Ligases play an important role in linking DNA breaks during excision repair, DNA damage, or spontaneous lesions such as basal sites or oxidized bases.

Which energy transformation occurs first in a coal-burning power plant?.

lutik1710 [3]

When coal is burned, chemical potential energy is transformed into thermal energy, light energy, and sound energy. Therefore only the thermal energy is used for their electricity production.

Hope this helps :))

Throwing a ball is an example of an energy

tino4ka555 [31]

Answer:

potential energy

Explanation:

Work changes potential and kinetic energy. When you throw a ball, you transfer energy to it and it moves. By doing work on the ball, you can give it which is the energy of motion. Any moving object has some kinetic energy.
