dna
important scientist
Watson and crick
Discovered the structure of the x2 Helix
Gregor Mendal
discovered the fundamental laws of inheritance
pea pod experiment
co-dominance
the alleles of a gene pair in a heterozygote are fully expressed, the offspring will have traits that are emit her dominant nor recessive of one another.
incomplete dominance
one allele for a specific trait is not completely dominant over another allele
Dihybrid cross
mating between 2 different first generation individuals that differ in 2 traits of particular interest
SsYy x SsYy
Monohybrid Cross
mating between 2 different alleles at one genetic locus of interest
Aa x Aa
Rosalind Franklin
responsible for much of the work/research that led to the discovery of the double helix
covalent bond
a chemical bond that involves the sharing of electron pairs between atoms
Deoxyribose sugar
a sugar that is a constituent of nucleic acids
peptide bond
a bond that forms between the carboxyl group of one amino acid and the amino acid group of the adjacent amino acid
amino acids
are used to make protein
chromatin
the combination or complex of DNA and proteins that make up the contents of the nucleus of a cell
chromosome
It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences
mitosis
the process in which the chromosomes in the cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus
meiosis
a special type of cell division necessary for sexual reproduction in eukaryotes, such as animals, plants and fungi
mRNA, tRNA, rRNA
use the amino acids to make protein
RNA Polymerase
an enzyme that produces primary transcript RNA and it is necessary for constructing RNA chains using DNA genes as templates which is called transcription
DNA transcription
a particular segment of DNA is copied into RNA by the enzyme RNA polymerase
splicing
a modification of the nascent pre-messenger RNA transcript in which introns are removed and exons are joined
somatic cells
any biological cell forming the body of an organism
replication
the process of producing two identical replicas from one original DNA molecule
helicase
unpackage an organism's genes
Nucleotides
monomers or subunits of nucleic acids like DNA & RNA
purine
Adenine
Guanine
pyrimidine
Thymine
Cytosine
hydrogen bonds
connects A to T and C to G
mutation
a change of the nucleotide sequence of the genome of an organism, virus, or extra chromosomal genetic element. it is random and can be for the better or the worst
DNA Polymerase
enzymes that create DNA molecules by assembling nucleotides and they are the building blocks of DNA
codon
the set of rules by which information encoded within genetic material is translated into proteins by living cells
genetic code
central dogma
an explanation of the flow of genetic information within a biological system
anti-codon
tRNA
an adaptor molecule composed of RNA
introns
any nucleotide sequence within a gene that is removed by RNA splicing while the final mature RNA product of a gene is being generated
exon
any nucleotide sequence encoded by a gene that remains present within the final mature RNA product of that gene after introns have been removed RNA splicing
Nucleus
holds the dna which holds the data for amino acids
ribosomes
cell organelles that consist of RNA and proteins and they are responsible for assembling the proteins of the cell
translation
the process where celluar ribosomes make proteins
nitrogenous base
bond nucleic acids together
genotype
the genetic makeup of a cell, an organism, or an individual usually with reference to a specific characteristic under consideration
phenotype
the composite of an organism's observable characteristics or traits, such as its morphology,biochemical or physiological properties, phenology, behavior, and products of behavior
germ cells
any biological cell that gives rise to the gametes of an organism that reproduces sexually
phosphate group
the group or radical obtained by removal of one or more hydrogen atoms from phosphoric acid
