DNA found in all living things that contains its genetic information.
RNA type of nucleic acid that contains ribose sugar

mitosis cell division process that results in genetically identical cells, same number of chromosomes.
meiosis cell division that results in new cells with half number of chromosomes.116:46:23

genome collection of genetic information
chromosome storage units of genes

homozygous dominant BB: alleles are same and dominannt
hetrozygous Bb: alleles are diffrent
hemizygous recessive bb: both alleles are the same and ressesive
recessive inheritance parents carry the trait without showing it
DNA vs RNA RNA is single stranded instead of double stranded RNA is made of ribose sugar instead of deoxyribose RNA has uracil instead of Thymine as nucleobase
translation vs transcription transcription occurs in the nucleus whereas translation occurs in ribosomes. And transcription uses DNA temp to form RNA whereas translation transcribes the mRNA molecule to create new proteins.
3 types of RNA messenger DNA (mRNA) Ribosomal DNA (rRNA) Transfer DNA (tRNA)
