Step 5: The amino acid carried on the first tRNA forms a peptide bond with the amino acid on the second tRNA and detaches from the first tRNA. Step 6: The first tRNA is kicked out as the rib ...

... 46. Many of the eukaryotic genes contain two or more protein-coding exons and intervening non-coding introns. 47. In prokaryotic cells, translation of an mRNA into protein can begin from the 5’ end of the mRNA even while the 3’ end is still being copied from DNA. 48. In eukaryotic cells, the primary ...

Ribozymes have been shown to process pre-RNA for ribosomal RNA (rRNA) in some organisms. In these cases, the intron itself is the ribozyme, and the introns ...

So what is a telomere anyway? • A telomere is a repeating DNA sequence (for example, TTAGGG) at the end of the body's chromosomes. • The telomere can reach a length of 15,000 base pairs. • Telomeres function by preventing chromosomes from losing base pair sequences at their ends. They also stop chr ...
