how do you make trna and rrna
|
from a dna strand, much like the same way you make mrna
|
|
|
making mrna is called
|
transcription
|
|
|
making a poly chain from mrna is called
|
translation
|
|
|
protein synthesis involves ...and ...
|
transcription and translation
|
|
|
a DNA segment that provides info for the synthesis of one polypeptide chain
|
gene
|
|
|
How does RNA differ from RNA
|
its single stranded, has sugar ribose, and has uracil instead of Thymine
|
|
|
DNA specifies the structure of lipids and carbohydrates too
|
False, only protein
|
|
|
amino acid specifying informational sequences
|
exons
|
|
|
what RNAs act to translate the message
|
trna and rrna
|
|
|
in the cell, where does transcription take place
|
in the nucleus
|
|
|
specifies where Mrna synthesis will start
|
promoter
|
|
|
what binds to the promoter and starts transcription
|
RNA polymerase
|
|
|
what molecule unwinds the DNA to be transcribed
|
RNA polymerase
|
|
|
the three bases that correspond from DNA to MRNA are called
|
codons
|
|
|
some amino acids have more than one codon for its code
|
True, helps protect agains transcription errors
|
|
|
Does the MRNA immediately get used as a messanger
|
no, gets edited by a splicesome, takes out the introns
|
|
|
whats the job of Trna
|
get the amino acids from the cytosol to the ribosome
|
|
|
each trna binds to a specific amino acid
|
T
|
|
|
the three base sequence that attaches to the mrna codon
|
the anticodon
|
|
|
how many binding sites does the ribosome have
|
three
|
|
|
a bunch or ribosomes all reading the same strand of Mrna
|
polyribosome
|
|
|
translation stops with a
|
stop codon
|
