Do you want to learn about the molecular properties of DNA and the rules that govern the recombination of those properties? Have you taken a biochemistry course or any other material on biology, but you aren’t sure how to apply it? Want to know how to interpret the DNA The Molecule Of Heredity Worksheet? The following should help.
DNA (deoxyribonucleic acid) is a structural protein containing two strands of nucleotides, a four-stranded helix. Each strand has a terminal telomere on one end. As the DNA is repeated through time, each pair of strands grows longer, the telomeres on each end shorten, and the DNA can no longer contain all the genetic information required for life. Life ends there. Or it begins, depending on the species of life.
DNA has two fundamental biochemical rules governing its replication: DNA replication delays by half the time that it takes to add a gene from one chromosome to another, and DNA polymerase allow each strand to separate easily from the other strands, with DNA transfer usually occurring at the junction between two chromosomes. The separation of the DNA strands is often called recombination, although it is sometimes known as recombination inversion. Recombination occurs when one strand of the DNA breaks away from the other strand and becomes attached to a new region of the chromosome.
The DNA structure can be viewed from the inside. A repetitive unit of DNA, repeated over, is made up of a sequence of bases. There are twelve such bases in a DNA molecule. These bases, which occur in the same order throughout the DNA molecule, form the bases of your DNA. Each base is made up of a nitrogen atom and a phosphate group.
Each base, or nucleotide sequence, is also made up of an alphabetic sequence of bases, called a codon. Each base is repeated four times in each strand of DNA, creating a four-base string, which is then joined together by the base sequence of the next strand. The DNA is repeated eight times before it is recombined and repaired, and each strand is joined with the adjacent strand.
Once the recombination occurs, the DNA becomes more or less spherical, with one or more lumps at the ends of the DNA strand. These lumps contain nucleotides, which repeat the base sequence of the previous strand, as it is joined to the new strand. When the DNA recombines, the lumps become untangled and separated from the remaining strand, allowing the DNA strands to move freely and react independently of each other.
In DNA, the precise lengths of the bases have different meaning for the different types of organisms, because the characteristics of each are in turn determined by the proportion of each kind of base to the remainder of the DNA molecule. If you study the DNA The Molecule Of Heredity Worksheet and come up with a pattern that fits within the rules, you can be more confident that you are on the right track.
