Synthesis of TTP from UTP is to be determined. Concept introduction: Pyrimidine is a heterocyclic nitrogenous base, which is found in the DNA and RNA. DNA has cytosine and thymine as pyrimidines, and RNA has uracil and cytosine has pyrimidines. It is a six-membered ring that contains two nitrogen atoms at 1 and 3 positions.

True or False. Explain. A) At no time during protein synthesis does an amino acid make direct contact with the mRNA being translated. B) Because the two strands of DNA are complementary, the mRNA of a gene can be synthesized using either strand as a template.

I am more confused. how about we start from begining, you post answers on here, and then we go from there? 1. Identify the open reading frame in the following DNA sequence, the protein that this gene encodes for, its function, and the source. 2. "Look carefully at the DNA sequence and identify the start site for transcription" 3. Click on the DNA sequence from the start site of transcription, select all of the sequence, and copy the sequence. Go to the National Center for Biotechnology Information (NCBI) website http://www.ncbi.nlm.nih.gov/. Click on BLAST on the right-hand side under “Popular Resources.” BLAST is a program that will allow you to find the protein sequence for the DNA sequence (gene) you submit. Next click on blastx (translated nucleotide protein). Paste the DNA sequence into the box under “Entry Query Sequence.” Scroll down and click BLAST. The search may take a few seconds; the page will keep updating until the search is completed. You do not need to enter any…

BONUS QUESTION! In neurons, the proteolytic enzyme y-secretase produces the Aß amyloid peptides shown below. The AB40 peptide is thought to play a protective role in the neuron. However, the AB42 peptide appears to be toxic since it is found in the amyloid plaques that cause Alzheimer's Disease (AD). AB40 and AB42 are identical, except that AB42 contains two extra amino acid residues (shown in red) at the C-terminal end. Based on your knowledge of amino acids and proteins, which of the following factors is most likely to explain the greater plaque-forming activity of AB42 compared to AB40? Sequence of Aß40: DAEFRHDSGYEVHHQKLVFFAEDVGSNKGAIIGLMVGGVV Sequence of AB42: DAEFRHDSGYEVHHQKLVFFAEDVGSNKGAIIGLMVGGVVIA O The greater length of AB42 makes it more likely to aggregate and form plaques. O AB42 has a lower pl than AB40, which makes it more likely to aggregate at physiological pH. O AB42 is more hydrophobic than AB40, which makes it harder to clear from the cell and thus more likely to…
