The message of the DNA code is information for building what?
What are the building blocks of proteins?
A three part code on mRNA is called a
What are the three basic differences between DNA and RNA?
a) RNA is single stranded while DNA is double stranded
b)RNA sugar=ribose DNA sugar= deozyribose
c) RNA has Uracil while DNA has thymine
What are the three types of RNA?
mRNA, tRNA, rRNA
What are the two stages of Protein Synthesis?
transcription and translation
The type of RNA that carries the instructions for how to make a protein from the nucleus to the ribosomes is which one?
In mRNA, each codon is the code for specific what?
Genes are made of what?
How many amino acids are there?
How many nitrogen bases are there in a codon?
In what part of the cell are proteins made?
ribosomes in the cytoplasm
How many different nucleotides are there?
What is the purpose of transcription?
copy one gene from the DNA molecule
Proteins are made by joining together long chains of what?
the order in which the amino acids are joined determine what?
determine the type of protein that is made
the three codons represent three different what?
What happens during translation?
the cell must translate the base sequence of an mRNA molecule into the amino acid sequence of a protein
During translation, the cell uses information from mRNA to produce what?
Steps of protein synthesis:
a) in the nucleus, DNA transcribes RNA
b) the RNA is sent to the cytoplasm in the form of mRNA
c) the mRNA attaches to a ribosome
d) each codon of the mRNA molecule moves through the ribosome, the proper amino acid is brought into the ribosome by the tRNA.
e) the amino acids are lined up in the right order
f)the ribosome hitches the amino acids together with peptide bonds and proteins are made
each type of tRNA molecule links a particular what with a particular what?
a particular mRNA codon with a particular amino acid
As a tRNA arrives at a ribosome, it carries a specific amino acid at one end called a what?
A switched amino acid may have what kind of affect?
it could or could not change the protein
