Genes.
A gene is a section of a DNA molecule that contains the information to code for one specific protein. The gene contains the code that determines the structure of a protein.
These terms represent the stages that occur in alternation of generation. Alternation of generation describes the process in the life of some eurkaryotes [mostly plants and protists], it refers to the alternation in form which occur in these organisms. One form is usually diploid with 2n chromosomes, this is called the sporophyte while the other form is haploid with only one set of chromosomes and it is called the gametophyte.
The spores go through mitosis and produce gametophyte, the gametophyte produce gamete. Two gametes fuse together to become a zygote.<span />
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.
