Question
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?

DNA is replicated into two daughter cells.
tRNA delivers the DNA to the ribosome.
mRNA is translated into amino acids.

number 4 is "The protiens are expressed differently in each cell" and number 5 is "mRNA is translated into amino acids"

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 :)

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.)
