Genetics
Summary:
Genes are the small part of DNA, the genes are like puzzles pieces of the long nucleotides strand. They come in different types, being called Alleles, the genes are inherited by one another and that is determined by the common things that are passed by generation to generation, gene by gene. An important detail about “ Alleles” is that they are represented by a capital letter and a lowercase letter. The upper case letter will present the dominant trait of alleles and the lower case letters represent the recessive trait of alleles. The next important thing of genes are segregation, the segregation of alleles are during formation of gametes which is when each cell is separated from the DNA chain. Within genes, as said before they have traits, most of the traits are polygenic, they are determined by a certain number of different genes located on different chromosomes. Genes are for different things, they want to present a physical and mental appearance from interhanince, another trait of genes is the phenotype which is in support of physical appearance. This gene can determine whether someone or something will be tall or short, light or dark, etc. An organism is able to inherit two of the same alleles, it makes a combination of either the same gene or two different genes, creating the trait genotype.

Essential questions:
What are genes? How and why are genes hereditary and how does it work to be hereditary? |
Key Terms:
Codon - three cbp’s (complementary-base pairings) that form a unit of genetic code in a DNA or RNA molecule
Complementary-base pairing -sets of hydrogen-linked nucleobases that make up nucleic acids DNA and RNA
Adenine and Thymine, Guanine and Cytosine, Adenine and Uracil, Guanine and Cytosine
mRNA - (Messenger RNA) transfer the information from DNA to the cell machinery that makes proteins
Peptide bond - a chemical bond formed between two molecules
Transcription - the first step of gene expression where an RNA polymer is created from a DNA template
Translation - the process of creating proteins from an mRNA template
tRNA - molecules that act as temporary carriers of amino acids
