Chapter 8 Genetics -- Part 2
The process of DNA replication is very accurate.
The incorrect base is excised and replaced with the correct one.
Unwound parental DNA is the leading strand.
The double helix is undone by theidases.
The ligase joins spontaneously.
The daughter's chromosomes can be virtually identical to the parent's.
The functions of DNA gyrase, DNA ligase, and DNA polymerase can be described.
We can now see the processes that occur in a cell.
We will see that trans ferRNA is involved in synthesis.
A strand of mRNA is created using a specific portion of the cell's DNA.
The G is dictated by the Termination DNA template.
The adenine is dictated by the adenine in the DNA template.
An adenine in the DNA template causes the uracil to be in the mRNA.
If the base sequence of the template portion of DNA is 3'-ATGCAT, the newly synthesized strand will have the same base sequence.
The transcript reaches some bases.
The helix re-forms after the strand is released.
The overall flow of genetic information within a cell is shown in the orienting diagram.
We've seen how the genetic information in DNA transfers serves as a template for the synthesis of a gene.
Like to be transcribed.
We will see how the 5' S 3' direction is used for synthesis.
The source of information for the synthesis of proteins can be found in the form of RNA syn.
Messenger RNA is an intermediate three nucleotides.
The sequence between the permanent storage form, DNA, and the process that of codons on an mRNA molecule determines the sequence of uses the information, translation.
Each overview has a process codon.
There are four codons in C and alanine.
61 are sense codons and 3 are nonsense codons.
AUG is the codon that starts the synthesis of the pro Gln tein molecule.
The start AUG code for formylmethionine is different to the methionine found in other parts of the protein.
A growing chain of G acid.
There are bases that are compatible with a codon.
A molecule can base-pair with another molecule.
The three nucleotides in the codon are recognized by the tRNA.
The functions of the ribosome codon are listed as the first, second, and third positions.
Each set of three assembles the amino acids brought there into a chain, which is then represented by a three-letter word.
The codonAUg is the beginning of the process of synthesis.
After the ribosome joins the first two amino acids.
The first tRNA molecule leaves the ribosome in prokaryotic cells.
The start codons of an mRNA peptide bonds are formed between them, and a polypeptide being transcribed are available to ribosomes before the entire chain results.
The translation molecule is made.
The nucleus is where transcription takes place.
The ribosome, the mRNA, and the tRNAs need to be completely synthesised and moved through to be used again.
Before it tion, the RNA undergoes processing.
The ribosome will allow leaves in the nucleus as it moves along.
The regions of genes that start to be exposed are in eukaryotic cells.
Noncoding DNA can interrupt the code for additional ribosomes.
The first translation comes together on the assembled ribosome.
The P site is where this first tRNA is located.
The second amino acid is carried by the tRNA.
The first tRNA is released from the E site as the ribosome continues to move along.
The goal of translation is to create a source of biological information.
