Question

which statement about the central dogma is false?
ribosomes read the mrna 5’→3’
dna polymerase reads the template dna 5’→3’
rna polymerase reads the coding dna 5’→3’
rna polymerase does not require a primer to begin rna strand synthesis
ribosomes and dna polymerase both require atp to function

Explanation:

1. Ribosomes read mRNA in the 5' - 3' direction during translation, so the first statement is true.
2. DNA polymerase reads the template DNA strand in the 3' - 5' direction while synthesizing a new strand in the 5' - 3' direction. So the statement that DNA polymerase reads the template DNA 5' - 3' is false.
3. RNA polymerase reads the coding DNA (sense strand) in the 5' - 3' direction during transcription, synthesizing RNA in the 5' - 3' direction using the non - coding (antisense) strand as a template.
4. RNA polymerase does not require a primer to initiate RNA synthesis, unlike DNA polymerase.
5. Both ribosomes (for translation) and DNA polymerase (for DNA replication) require energy in the form of ATP for their functions.

Answer:

B. DNA polymerase reads the template DNA 5' → 3'
