Mastering Biology Questions

Put the following steps of DNA replication in chronological order.
1. Single-stranded binding proteins attach to DNA strands.
2. Hydrogen bonds between base pairs of antiparallel strands are broken.
3. Primase binds to the site of origin.
4. DNA polymerase binds to the template strand.
5. An RNA primer is created.

2, 1, 3, 5, 4

A null allele is _____.

a mutated form of a gene that does not make a functioning product

Which statement is correct concerning DNA synthesis catalyzed by DNA polymerase?

The new DNA strand is synthesized in the 5'→3' direction; the template strand is read in the 3'→5' direction.

In the process of transcription, _____.

RNA is synthesized

What is the start codon?

AUG - methionine

What are the stop codons?


The mRNA is translated in a 5' → 3' direction.


Base pairing in mRNA synthesis follows slightly different rules than in DNA synthesis:

uracil (U) replaces thymine (T) in pairing with adenine (A).
The codons specified by the mRNA are then translated into a string of amino acids.

What amino acid sequence does the following DNA nucleotide sequence specify?

3' - AUG-UCA-UGC-CAU - 5'
3' - Met - Ser - Cys - His - 5'

Codons, the three base sequences that code for specific amino acids, are part of _____.


Using the predictions from the Meselson-Stahl experiment, what would be the composition of the DNA after three generations for the semi-conservative model?

6/8 14N strands and 2/8 hybrid strands
