• trinucleotide codons and amino acids

  What would be the sequence of a protein consisting of a repeat of each of these trinucleotides? If the sequence was read in a different reading frame, how would this affect the protein product?

• Different single-stranded RNA's are composed of 99 nucleotides

  There are 20 possible amino acids in the first position and 20 possible amino acids in the second position. That makes 20^2 = 400 possible dipeptides. A triptide is composed of two amino acids.

• Protein translation and the ER

  152901 Protein translation and the ER 1.

• Encoding a protein with a pair of conflicting signal sequences

  Therefore, which signal would win out in a protein that had both a mitochondrial localization sequence and an ER retrieval sequence?

• Genetics-From genes to protein, mutations.

  Its function will change because each protein have a different sequence corresponding to each function. Transcription and translation are the dogma of molecular biology. DNA is transcibed into mRNA by DNA Polymerase.

• DNA Sequence Analysis

  GOR IV and SOPMA predict secondary structure of a protein sequence based on sequence characteristics and multiple alignments with known sequences.

• From Genes to Proteins, Mutations & Inheritance of Traits or Genetic Disorders

  Question: For each of the two, you will need to first transcribe the mRNA, and then use the genetic code table to determine the amino acid sequence. Turn these in, and state whether the protein sequence changes for each.

• genes, proteins, mutations

  Translation is done by reading the RNA 5' to 3' and adding amino acids in the protein sequence from N-terminus to C-terminus.

• Protein Sequence Prediction

  This is an excellent book which talks about these methods and about protein secondary structure: Mount DM (2004). Bioinformatics: Sequence and Genome Analysis 2. Cold Spring Harbor Laboratory Press 2.
