sugar, phosphate group, and base
three parts of a nucleotide
double ringed, AG
single ringed, TCU
relationship between genome, DNA, genes, chromosomes, and alleles
Non coded regions in genes
coded regions in genes
DNA-double helix, AT GC, holds info, stays in the nucleus, deoxyribose RNA-Single helix, AU GC, transfers and moves proteins, leaves nucleus, ribose
Compare and contrast DNA to RNA
the process in which the replicated DNA is transcribed into a single strand of RNA. Occurs in the nucleus
dna-instruction book(stores information) mRNA-middle man molecule. DNA is copied to. Carries info out of the nucleus and into cytoplams
Role of DNA and mRNA in transcription
recognize and initiate protien-aug is recognized by tRNA and 2 ribosomal subunits. tRNA binds to mRNA as ribosomal subunits assemble around them. ELONGATE, TERMINATE
an alteration of sequences in bases of DNA. changes structure and function of protein produced
mutation where 1 base pair is replaced/deleted/inserted.
mutation that involves deletions of entire sections of DNA. more harmful
organisms, cells, and molecules are modified to achieve practical benefits.
manipulation of an organism's genetic material
bind to a particular base sequence and cuts the DNA, preventing a virus from reproducing w/in bacterial cell.
makes copies of target genes. DNA is amplified using this. Laboratory technique that repeatedly duplicates tiny pieces of DNA. Used in forensics.
golden rice prevents blindness, saves cost of farming and time, seedless watermelons, meaty turkey
Examples of genetically modified crops and why they are good.
DNA sequences is poured in gel and charge is applied
creation of a new individual with same genome as the doner. Surrogate egg-remove nucleus-add nucleus of real mother-fuse both-implant embryo in surrogate
