question
Suppose you want to design and build a house.How would you communicate your design plans with the constuction crew that would work on the house?
answer
I would have a blueprint with instructions.
question
Cells build large,complicated molecules,such as proteins.What do you think cells use as their "design plans" for proteins?
answer
They use DNA.
question
Look at the SIMILATION pane.Is the displayed segment a part of the DNA or RNA molecule?How do you know?
answer
It is DNA.
question
Which RNA base bonded with the thymine?
answer
Adenine.
question
Look at the simulation pane.Is the displayed segment a part of the DNA or RNA molecule?How do you know?
answer
It is DNA,because it contains THymine in it.
question
Which RNA base bonds with adenine?
answer
Uracil
question
RNA polymerase is a type of enymene.Ensymes help chemical reactions occur quickly.Click the relase enzyme button,and describe what happens.
answer
The strand split apart.
question
Which RNA base bonds with cytosine?
answer
Guganine
question
Which RNA base bonds with adenine?
answer
Uracil
question
Which RNA base bonds with guanine?
answer
Cytosine
question
Which RNA base bonds with cytosine?
answer
guanine
question
In molecules of RNA ,uracil takes the place of the DNA base
answer
Thymine
question
Which RNA base bonds with guanine?
answer
cytosine
question
What is the nucleotide seuqence of the mRNA strand you built?
answer
Aug-Cug-Acc-Uag
question
IN molecules of RNA ,uracil takes place of the DNA base?
answer
thymine
question
What would be the complematry strand of mRNA?
answer
AUG-CCU-AUU-GAU-GGC-CCA-UAA-GUU
question
What is the nucleotide suquence of the mRNA you built?
answer
Aug-Cug-Acc-Uag
question
What would be the complementarty strand of mRNA?
answer
AUG-CCU-AUU-GAU-GGC-CCA-UAA-GUU
question
How would a change to the sequence of nucleotides in a DNA segmant afftct the mRNA transcribed from the DNA?
answer
It would change the suquence in the Mrna.
question
Which andicondon do you think would attach to the mRNA's start codon?
answer
AUG
question
Place the next 2 tRNA molecules on the mRNA strand- what happens-
answer
They form a strand
question
UAG-as well as UAA and UGA-is a example of a stop codon.Molecules called release factors blind to stop condons.Place the release gactor on the mRNA molecule.What happens?
answer
It makes the protein.
question
Why do you think stop and start codon siginals are neccessary for protein synthesis?
answer
It is what makes the correct protein.While the stop codon siginals,finishes off the protein.
question
Desribe the processes of transcription and translation in your own words.Based on what you have observed in Gizmo.
answer
Transcription- It is when DNA strand splits in half and makes the mRNA molecule.
question
Translation
answer
The completed strand pairs up with odons and completes the protein.
question
What amino acids do the following codons code for?
answer
AUG-Methionine CUG-Leucine ACC-Threonine UAG-Stop
question
Suppose you wanted a protein that cobsists of the amino acid sequence methionine,asparagine,valine,and histidine.Give a mRNA sequence sentance that would code for this protein.
answer
AUG AAU GUU CAU
question
How do genes determine the traits of a ornanism?explain in detail
answer
A gene is a sequence of nucleotides,on 1 strand of DNA while a group of 3 nucleotides called Codon determine the primary structure.1 or more polytides may join to form a protein.
question
How might this offset transpriction or translation errors?
answer
It offsets them from becoming errors because of how many codons there are.
question
Does the 2nd statement support the theory of evlution?Explain why or why not.. If possible,discuss your answer with your teacher and classmates.
answer
Yes it does,because in translation between mRNA and amino acids would be different to one another in living things it might mean that they are not related.
