Answer:
Wild type
Explanation:
It refers to the phenotype that is found in nature. Naturally the form that is commonly seen in nature and is used for experiment is this type only.
This concept is useful in many experiment as it can be used as a model organism. Example: Drosophila melanogaster.
Manipulation of genes produces different type of phenotype other than wild type which is not generally seen in the nature.
Answer:
the claim, evidence, and rationale
Explanation:
Two nucleotides on the same strand form a <u>Phosphodiester bond </u>while two complimentary bases on opposite strands form <u>Hydrogen bonds</u>. An a-t base pairing forms <u>2</u> such bonds.
The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.
Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.
