What is RiboNucleic Acid?
primary role of RNA is to convert the information stored in DNA into proteins.
Differences Between DNA and RNA
DNA:
* Double Stranded
* Sugar is deoxyribose
* Located in the Nucleus
* Contains Thymine as a base
RNA:
* Single Stranded
* Sugar is ribose
* Cytoplasm
* Contains Uracil as a base
What enzyme is responsible for DNA Replication, How?
DNA Polymerase; joins individual nucleotides to produce a new DNA strand
Which organelles are involved?
- Nucleus (has genetic info)
- Ribosomes (makes proteins)
- ER (transports proteins)
- Golgi Apparatus (Modifies + Ships)
What are mRNA Vaccines
Vaccines that have spikes, teaches body to recognize and fight agiainst virus before it happens
Three types of RNA
messengerRNA: Contains recepie for building proteins
ribosomalRNA: used to build ribosomes
transportRNA: transfers amino acids to ribosomes
What is Transcription?
Process that occurs in the Nucleus
- copying RNA into DNA
- first copy of RNA contains introns & extrons
- introns aren’t being used to theyre removed
- mRNA doesn’t have introns
- Introns stay in nucleous, extrons leave in mRNA
What is Translation?
protein synthesis process (nuclotide/base -> codon -> amino acid -> protein)
Characteristics of Huntington Neurodegenerative Disease
- Neuro = Brain (neurons)
- Degenerative = slowly breaking down
- repeated sequence of DNA (too long)
- Abnormal Proteins
- Abnormal movements & cognitive problems
- onset at 40, longer chain = earlier onset
- disease has over 36 sequences (10-35 is normal)
Autosomal
affects one of the 22 chromosomes (not the one gamate chromosome)
Codons
Three letter words formed by three bases/nucleotides, corresponds to one amino acid (3 = 1)
AntiCodon
Corresponding codons, can only bond with specific base/nucleotides
Polypeptide
String of amino acids
What is the Central Dogma of molecular bio?
Information is transferred from DNA to RNA to Protein
What is gene expression
the way in which DNA, RNA and proteins are involved in putting genetic info into action in living cells
