if the second c in the original dna template mutates with t what is the affect on the protein ?
if the second a in the original dna template mutates with g what is the affect on the protein ?
if the first g in the original dna template mutates with A what is the affect on the protein ?
What is the affect on the protein ?
gag = glu --%26gt; acidic amino acid
aag = lys --%26gt; basic aminoacid
the protein will be affected if the mutation was in the active site
uua= leu
cua = leu
the protein will not be affected
cga = arg
uga = stop codon
the protein is truncated and will not be completed
Reply:That protein will not be completed.
Reply:protein have to increase content of the uric acid

Reply:d. The two chains of the DNA molecule seperate near the promoter
b. RNA polymerase binds to the promoter of the template chain of DNA
a. RNA polymerase attaches the first DNA (shouldn't this say RNA?*) nucleotide of the template chain
e. Complementary RNA nucleotides are added to the newly forming RNA molecule
c. RNA polymerase reaches the termination signal and releases the DNA and RNA molecules
*RNA Polymerase would only be laying down RNA nucleotides, not DNA ones...

1.translation:
a. occurs on the surface of the mitochondria
b. is the final process in the assembly of a protein
c. occurs during the synthesis of any type of RNA by use of a DNA template
d. is catalyzed by DNA polymerase
e. none of the above
2.what molecules carries protein-assembly instructions from the nucleus to the cytoplasm:
a. template DNA
b. mRNA
c. tRNA
d. rRNA
e. all of the above
3. A nucleotide is built from how many subunits:
a. one
b. two
c. three
d. four
e. five
Biology question... pls help!!?

Reply:1. E
2. B
3. sugar, base, and phosphate. that means C:3
Reply:1) E. - once the proetin has been assembled during translation it will often combine wit other ones to form tertiary and querturnary proteins
2) B. mRNA - messenger RNA - it takes the gene from nucleus to a ribosome where it can be read.
3) C. 3 subunits (1 phosphate 1 sugar 1 base)
