ribosomes
sporte | April 17, 2008In the class that I'm teaching, we found that several PCR products, amplified from the 16S ribosomal RNA genes from bacterial isolates, contain a mixed base in one or more positions.
We picked samples where the mixed bases were located in high quality regions of the sequence (Q >40), and determined that the mixed bases mostly likely come from different ribosomal RNA genes. Many species of bacteria have multiple copies of 16S ribosomal RNA genes and the copies can differ from each other within a single genome and between genomes.
Now, in one of our last projects we are determining where…
sporte | April 16, 2008Ribosomes are molecular machines that build new proteins. This process of synthesizing a protein is also known as translation.
Many antibiotics prevent translation by binding to ribosomal RNA. In the class that I'm teaching, we're going to be looking at ribosome structures to see if the polymorphisms that we find in the sequences of 16S ribosomal RNA are related antibiotic resistance.
This is related to our metagenomics project where we investigate the polymorphisms we find in 16S ribosomal RNAs.
This 6 minute video introduces ribosomes, discusses where they're found, what they're made of,…
