Answer:
Details about DNA are given in the explanation section. Hope it will be helpful for you.
Explanation:
DNA, or deoxyribonucleic acid, is the hereditary element in humans and almost all other organisms. Nearly every cell in a person’s body has the same type of DNA. Most DNA is found in the cell nucleus (nuclear DNA), but a small quantity of DNA can also be found in the mitochondria (mitochondrial DNA or mtDNA).
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same type in all people.
DNA bases pair up with each other, A with T and C with G, to form units that are called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. A base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
A valuable feature of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
Because you might have just done something different with the experiment and messed up someway during the test
The answer is true. Their strike can break aquarium glass and even split open human thumbs.
Answer:
Resistance bacteria survive in greater numbers and pass the trait to their offspring
Explanation:
Antibiotics are chemicals which are used in the treatment of bacterial infections. The bacteria sometimes have some form of immunity or resistance to a particular antibiotic due to a host of underlying factors.
Once resistance appears in a bacterial population, it spreads rapidly. The trait of immunity or resistance to such antibiotic is then passed as a trait from one generation to another.
