Transcription
What happens during transcription
a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell
What happens during translation
proteins are made using the information stored in the mRNA sequence.
What dose MRNA mean
Messenger rna
What dose tRNA stand for
Transfer rna
What dose rRNA stand for
Ribosome rna
What are the key points of transcript?
a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell
What are the 4 steps of translation?
tRNA charging, Initiation, Elongation, and Termination
What does the mRNA do?
instructs cells in the body to make specific proteins
Can tRNA replicate itself?
Yes, it can self assemble
What does RNA do to the body?
Makes proteins
What are the 3 main stages of transcript
initiation, elongation & termination
What 3 things are needed for translation?
mRNA, ribosomes, transfer RNA (tRNA) and various enzymatic factors
What is the purpose of the mRNA?
directs the cells to make a protein using its natural machinery.
What creates tRNA?
RNA polymerase
What are the 4 things in RNA?
adenine (A), uracil (U), cytosine (C) or guanine (G).
Why is transcription important in DNA?
it is the main point at which the cell regulates which proteins are to be produced and at what rate.
Where does translation occur ?
on ribosomes in the cell cytoplasm
What are the 3 functions of mRNA?
provides the template for protein synthesis during translation
Where does tRNA get produced?
In the nucleus
Where is RNA found?
In cells
What happens to DNA after transcript ?
the DNA double helix unwinds and RNA polymerase reads the template strand, adding nucleotides to the 3′ end of the growing chain
Is DNA directly involved in translation?
DNA is not directly involved in its process
Where does mRNA go?
the cytoplasm
Where does tRNA enter?
the ribosome
Where does RNA travel from?
the nucleus to the cytoplasm
