1. Which of the following demonstrates the central dogma of molecular biologists?(1 point)
Gene expression relies on environmental factors that determine which traits are dominant.
DNA and RNA mutate into either harmful or helpful effects on the human body.
DNA and RNA hold the code to create proteins that are the key to gene expression.**
Proteins replicate DNA which gives the expression of traits to an organism.
2. After the amino acid chain leaves the ribosome, what organelle then folds, modifies, and transports the protein? (1 point)
Ribosome
Cytoplasm
Lysosome
Endoplasmic Reticulum**
3. Look at the DNA sequence.
C G T T A C T G C A A T

4. Which of the following best describes how a blood cell and skin cell have the exact same DNA sequence and yet look different and perform different functions?(1 point)
The cells mutate during transcription.
The tRNA uses a different sequence in each cell during transcription.**
The proteins are expressed differently in each cell.
The cells discard the DNA that is not in use.
5.Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She explained the process in the following steps.
1.DNA is transcribed into mRNA.
2.Amino acids form a chain.
3.The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
DNA is replicated into two daughter cells.
tRNA delivers the DNA to the ribosome.
mRNA is translated into amino acids.
Polypeptide chains express gene traits.**
The answers for the quick check you are working on in 2021 are:
1. C:DNA and RNA hold the code to create proteins that are the key to gene expression
2.C:Endoplasmic Reticulum
3.A: CGTGACTGCAAT I GCACTGACGTTA
4.D: The proteins are expressed differently in each cell.
5. D: mRNA is translated into amino acids.
Hope this helped :)
number 4 is "The protiens are expressed differently in each cell" and number 5 is "mRNA is translated into amino acids"
Thank you helper it was 100% correct
4 and 5 are incorrect.
YourHelper is correct exept they changed one.
2. Not all parts of a gene code for a protein. A non-coding section is called an intron. You know that base sequences are transcribed into mRNA and then translated into protein. How might a cell prevent an intron from being expressed as a protein? (D. remove the intron before translation occurs.)
YourHelper IS RIGHT I GOT A 1OO%
1) A:DNA and RNA hold the code to create proteins that are the key to gene expression
2) C:Endoplasmic Reticulum
3) B: CGTGACTGCAAT / GCACTGACGTTA
4) D: The proteins are expressed differently in each cell.
5. D: mRNA is translated into amino acids.
Chris and the other guy was correct i made a 100
1. DNA and RNA hold the code to create proteins that are the key to gene expression.
2. Remove the intron before translation occurs.
3. C G T G A C T G C A A T
G C A C T G A C G T T A
4. The proteins are expressed differently in each cell.
5. mRNA is translated into amino acids.
100% !!!!!!!!
yourHelper is right
girl was correct
10/20/21 your helper is right i got 5/5
whyme you mustve gotten something mixed but sorry cuz i got 5/5 100%
Your helper and girl are 100% correct
Thank you, girl
I got 100%
5/5! thx your helper!
Your helperβs answers are still correct as of 11/12/21, but the letters are different. So make sure you look for the answer and not the letter d or c
Your helper is correct 100%
Thank you, your helper too :)
@.-. we're taking this the same day bro
Your helper and girl are correct! Thanks!
The answers to this are correct, I reviewed it after I tested it.
1. DNA and RNA hold the code to create proteins that are the key to gene expression.
2. Endoplasmic Reticulum.
3. C G T G A C T G C A A T | G C A C T G A C G T T A
4. The proteins are expressed differently in each cell.
5. mRNA is translated into amino acids.
yourhelper was 100% correct for me. Thanks :)
10/22/2021
yeah they are 100% correct
1. A
2. D
3. C
4. A
5. C
These are the correct answers for this quick check, you're welcome
lmaoo everyone taking this right at the same time huh
your helper is right
Combo of girl and YourHelper is 100% correct
βUserβ is correct
10/21/22
helper is still right
100% thx your helper π
Hope this helps is right π
The answers are DBDDB as of today
Yourhelper is 100% correct!!
