DNA
Where is the DNA mainly located inside a cell?
Inside the nucleus.
The process by which the message from DNA is rewritten into RNA.
Transcription
What is the anticodon corresponding to the codon GUA?
CAU
Decode CGT CCA TTC from DNA to mRNA (messenger RNA)
GCA GGU AAG
What is DNA and what is its function?
The blueprint of life; contains the instructions for making protein within the cell.
The language of mRNA instructions read by ribosomes in 3 letter sequences
Codons
What is the maximum number of amino acids that could be coded for by delectation mutation?
3
What does transcription and DNA replication both have in common?
They both involve making copies of the DNA in a cell. Transcription copies the DNA into RNA, while replication makes another copy of DNA
What is the structure of DNA called, and how came up to it?
Double-helix structure by Watson & Crick.
The form of the RNA that carries each amino acid to the ribosome to form the polypeptide chain(protein)
tRNA
Where the DNA translation occurs?
In the cytoplasm
Which enzyme makes a new strand of DNA?
DNA polymerase
What is the DNA helix made out of?
The back bone of the molecule is alternating phosphates and deoxyribose sugar; the "teeth" are nitrogenous bases.
The main enzyme that is responsible for copying a DNA sequence into an RNA sequence
RNA polymerase
What are the 3 stages of the DNA translation?
Initiation, elongation, termination
How many stages occur in a ribosome, and what are they
entry of tRNA, taking the AA and adding it to the protein, ejection of the tRNA
What are the names of the two nitrogenous bases, their corresponding nucleotide bases, and which pairs form?
The two nitrogenous bases are Pyrimidine and Purine; Cytosine and Thymine are Pyrimidines, and Adenine ande Guanine are Purines; The pairs are A-T and C-G.
The process that takes place before the mRNA is sent to the ribosome. Some RNA bases are removed in order to create a final draft of the mRNA
RNA editing
What is the name of the chain that is formed after decoding an mRNA molecule?
Polypeptide chain
What is a tRNA
A piece of RNA with a codon corresponding to the AA it carries
