A possible sequence of nucleotides in the DNA that would code for the polypeptide sequence –Phenylalanine, Leucine-Tyrosine-Cysteine- would be:

Depolarization is the process of restoring resting potential

Use the following diagram to answer the question below: Chose the appropriate letter. In the Meselson-Stahl experiment, bacteria were grown in a medium containing 15N (radioactive nitrogen) and were then transferred to an environment containing 14N.  Which of the above results would be expected after two DNA replications?

A particular eukaryotic protein is 300 amino acids long.  Which of the following could be the number of nucleotides in the DNA that codes for this protein?

Capping and tailing are done before translation

As a result of the light reactions, ___________ is(are) available to provide energy for ____________

Given the following codons and their corresponding amino acids (T & I /10)     UUU- Pheylalanine     CUA – Leucine     GCU – Alanine     AAA – Lysine a)  show the mRNA which codes for the short peptide, lys-ala-phe-leu.  Include what should come before and after this short message. (2 ) b)    Show the tRNAs that would line up at the mRNA and their anticodons (2) c)  Show the base sequence that would be found in the DNA double helix which carries the gene for this peptide.  Label the coding and template strand. d)    What if there was a frameshift at leucine.  A cytosine was inserted directly after the first cytosine (on the template strand).  How would the amino acid sequence be altered?  Would this alter translation? e)  When the DNA was replicated which enzymes were responsible for this error?

If cytosine makes up 22 % of the nucleotides in a sample of DNA from an organism, then adenine would make up what percent of the bases?

The processing of the primary transcript involves

When a ribosome first attaches to an m-RNA, two t-RNAs bind to the ribosome.  The first t-RNA that recognizes the initiation codon binds to the:
