Central Dogma: Transcription & Translation - Case Studies
Q. What is a key difference between DNA and RNA?
-
A.
DNA is single-stranded, RNA is double-stranded
-
B.
RNA contains uracil instead of thymine
-
C.
DNA is found in the cytoplasm, RNA is found in the nucleus
-
D.
RNA is more stable than DNA
Solution
RNA contains uracil (U) in place of thymine (T), which is found in DNA, making this a key difference between the two nucleic acids.
Correct Answer: B — RNA contains uracil instead of thymine
Q. Which process directly follows transcription in the central dogma?
-
A.
Replication
-
B.
Translation
-
C.
Splicing
-
D.
Translocation
Solution
Translation directly follows transcription, where the mRNA is translated into a polypeptide chain at the ribosome.
