Study Notes
Translation
- Translates RNA nucleic acid sequences into chains of specific amino acids.
- Essential in the process of protein synthesis.
Replication
- DNA self-copies prior to cell division.
- Ensures genetic material is passed on during cell reproduction.
Transcription
- Copies DNA sequences in genes to make mRNA.
- Key step in transferring genetic information for protein production.
Uracil
- RNA nucleotide that replaces thymine found in DNA.
- Pairs with adenine during RNA processes.
mRNA (Messenger RNA)
- Carries genetic information from DNA in the nucleus to ribosomes.
- Acts as a template for protein synthesis.
tRNA (Transfer RNA)
- Delivers amino acids to ribosomes during protein synthesis.
- Helps translate the mRNA codons into amino acid sequences.
rRNA (Ribosomal RNA)
- Component of ribosomes that binds to mRNA.
- Facilitates assembly of amino acids in the correct sequence.
Ribosomes
- Sites of protein synthesis in the cell.
- Composed of rRNA and proteins.
Codon
- Triplet sequence of nucleotides on mRNA.
- Each codon codes for a specific amino acid.
Amino Acid
- Fundamental building blocks of proteins.
- Twenty different types combine to form various proteins.
Protein Synthesis
- Assembly of amino acids into proteins.
- Requires mRNA, tRNA, and ribosomes for completion.
Nitrogen Bases
- Components of the DNA ladder rungs: adenine (A), thymine (T), cytosine (C), guanine (G).
- A pairs with T and C pairs with G in DNA structure.
Nucleotide
- Subunit of nucleic acids composed of a sugar, phosphate group, and nitrogenous base.
- Key building block of RNA and DNA.
Ribose Sugar
- Sugar component of RNA, forming the backbone of the molecule.
- Contains one more oxygen atom than deoxyribose.
Deoxyribose Sugar
- Sugar component of DNA, forming its backbone.
- Lacks an oxygen atom compared to ribose sugar.
Guanine
- Purine nitrogen base found in both DNA and RNA.
- Pairs with cytosine during base pairing.
Cytosine
- Pyrimidine nitrogen base present in DNA and RNA.
- Pairs with guanine in base pairing.
Thymine
- Pyrimidine base present only in DNA.
- Pairs with adenine to stabilize the DNA structure.
Adenine
- Purine base in both DNA and RNA.
- Pairs with thymine in DNA and with uracil in RNA.
AUG
- Start codon that signals the beginning of protein synthesis.
- Initiates translation at the ribosome.
UAA
- Stop codon in mRNA that signals the end of protein synthesis.
- Also includes UGA and UAG as termination signals.
