Cat. 1
Q1. The entire name of RNA
What is Ribosenucleic Acid?
Q2. Describe a gene.
What is a section of DNA that expresses a trait?
Q6. Describe the shape of RNA
Single stranded
List one difference between RNA and DNA.
What is:
1. RNA is single stranded
2. RNA does not contain Thymine and contains Uracil
3. RNA contains ribose sugar instead of deoxyribose sugar
Q3. Chromosomes are located in this part of the cell.
What is a nucleus?
Q10. In DNA, Adenine bonds with ______ and Guanine bonds with _________ but in RNA, Adenine bonds with _______ and Guanine bonds with __________.
What is in DNA, Adenine bonds with Thymine and Guanine bonds with Cytosine but in RNA, Adenine bonds with Uracil and Guanine bonds with Cytosine?
Q8. List what the "rungs" (or middle) part of RNA is made of.
What are nitrogen bases?
Q7. List the two components that the RNA backbone (or "fence" or "side") is made of.
What is a ribose sugar and phosphate group?
List the 3 types of RNA.
rRNA (ribosomal)
mRNA (messenger)
Q11. List the function of mRNA.
What is to carry the message of DNA from the nucleus to the cytoplasm (ribosomes) and act as the skeleton in order to build proteins?
Q14. Proteins are made in this organelle.
What are ribosomes?
Q16. Explain the function of tRNA.
Bonus: Describe what tRNA is shaped like.
What is transfer RNA transfers amino acids (parts that make up proteins) and attach them together on the mRNA strand?
Bonus: tRNA is a three dimensional L shape.
Q4. DNA can be found in these two organelles.
What is nucleus and mitochondria?
Q13. Explain why RNA is necessary to act as the messenger. Why can't the code be taken directly from DNA?
What is DNA can't leave the nucleus (it is too large & tightly packed)?
Q15. Explain why some cells become skin cells and others become brain cells when ALL cell DNA is actually the same.
What is cell differentiation?
Some genes are turned "on" or "off". The body lets the cell know which cell types it needs and the cell will make those cell types.
