HSC Biology Syllabus - Genetics: The Code Broken? (Option) - All Dot Points Answered

9.7 ? Genetics: The Code Broken? (Option)1. The structure of a component provides the code for a polypeptide:?Describe the processes involved in the graft of information from DNA through ribonucleic acid to the production of a sequence of amino group acids in a polypeptide:?The structures involved in polypeptide synthesis are:DNA: A gene contains a sequence of bases to code for a protein. Every set of 3 bases is called a codon.

RNA: RNA is similar to DNA unpack that instead of deoxyribose as the sugar, it has ribose. It is one stranded, and instead of thymine, there is uracil. in that location are 3 forms involved in polypeptide synthesis:messenger RNA: Messenger RNA carries the genetic code outside the nucleus, into the cytoplasm, where it slew be read by ribosomes tRNA: Transfer RNA carries the amino acids to the ribosomes to link and form a polypeptide chain. tRNA are do like clover leaves; there is a different face for every amino acid. At the bottom of every tRNA grain is an anti-codon that binds to the codon on the mRNA strand. That is how the amino acid is conjugate to the codon.

Ribosomal RNA: Ribosomes are made up of protein and RNARibosomes: The ribosome is the active office for protein synthesis. It is made up of protein and RNA molecules. It can accommodate 2 tRNA at a time.

Enzymes: The enzyme that controls the formation of mRNA is RNA polymerase. There are, of course, many other enzymes that control the process.

?STAGE hotshot - Transcription:A double stranded DNA molecule in the nucleus unwinds a section of itself that consists of a single gene.

One of the strands coding for the gene exposes itself to the nucleoplasmThe enzyme, RNA polymerase moves along the strand, attaching bountiful RNA nucleotides to the DNA, with A-U and C-G, until the whole...
