These nucleotides are made of three parts, the phosphate group, the sugar, and the nitrogen base that will can be adenine, guanine, thymine, or cytosine.These molecules are connected via phosphate bonds. The nitrogen base connects to another nitrogen base on the opposite side in an double helix running anti parallel, meaning they run in opposite directions.]]> 2017-02-02 16:08:13 UTC https://padlet.com/lisle202/q9m5sjm9llgy/wish/151190204 ts20104 https://padlet.com/lisle202/q9m5sjm9llgy/wish/151194267 I couldn't get my part of the video done.

Another type of RNA, the Transfer RNA (tRNA) enters the ribosome. If the tRNA doesn't have the right amino acid it quickly leaves the site. This is repeated until the correct amino acid carrying tRNA is found. This is done about 100,000 times, so it isn't a concern for time. tRNA continue from the A site to the P site where their amino acid is connected to the other amino acids of the chain. Then the empty tRNA  exits the ribosome via the E site.]]> 2017-02-03 16:14:00 UTC https://padlet.com/lisle202/q9m5sjm9llgy/wish/151482599 ts20104 https://padlet.com/lisle202/q9m5sjm9llgy/wish/151484349 After the mRNA is modified, then the mRNA is now ready for translation once it leaves the nucleus.]]> 2017-02-03 16:19:00 UTC https://padlet.com/lisle202/q9m5sjm9llgy/wish/151484349 ts20104 https://padlet.com/lisle202/q9m5sjm9llgy/wish/151487538 As the tRNA (Transfer RNA) enters the ribosome and it matches, it leaves behind the peptide and it creates a long chain of peptides, often hundreds of length, then it cuts of and it is ready to be used.]]> 2017-02-03 16:28:08 UTC https://padlet.com/lisle202/q9m5sjm9llgy/wish/151487538 ts20104 https://padlet.com/lisle202/q9m5sjm9llgy/wish/152247206 After the mRNA is finished, it is modified to remove any sections that we don't need (exons) and we are left with the things that we only need (introns).]]> 2017-02-07 18:25:20 UTC https://padlet.com/lisle202/q9m5sjm9llgy/wish/152247206 ts20104 https://padlet.com/lisle202/q9m5sjm9llgy/wish/152250988 This is the finished protein.
