- know how to replicate DNA and which protein bases pair w each other (AT-GC) A Tiger Can Growl. Uracil can replace Thymine

Answer 1

In DNA, adenine pairs with thymine, while in RNA, adenine pairs with uracil. These base pairs are formed through complementary base pairing and are held together by hydrogen bonds.

Step-by-step explanation:

In DNA, the nitrogenous base pairs follow a specific pattern: adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G). This is known as complementary base pairing. Similarly, in RNA, uracil (U) replaces thymine, so adenine pairs with uracil instead.

The base pairs are held together by hydrogen bonding, with adenine and thymine sharing two hydrogen bonds and cytosine and guanine sharing three hydrogen bonds.

Answer 2

The key principles include base pairing (A-T or A-U, and G-C), codons specifying amino acids, and the role of DNA polymerase in DNA replication.

The statement "A Tiger Can Growl. Uracil can replace Thymine" is a mnemonic to remember the base pairing in DNA and RNA. It helps recall that adenine pairs with thymine (or uracil in RNA), and guanine pairs with cytosine.

The process of DNA replication involves the synthesis of a new DNA strand complementary to the existing one. During replication, the enzyme DNA polymerase facilitates the pairing of nucleotide bases according to the complementary base-pairing rules: adenine (A) pairs with thymine (T) in DNA, and uracil (U) in RNA; guanine (G) pairs with cytosine (C).

In summary, the key principles include base pairing (A-T or A-U, and G-C), codons specifying amino acids, and the role of DNA polymerase in DNA replication.
