|
what is the purpose of the bases in DNA
|
tells the cell which amino acids to link to make the CFTR protein |
|
|
where are proteins made
|
in the cytoplasm
|
|
|
why is DNA made here?
|
cannot pass through the membranes surrounding the nucleus. |
|
|
What is protein synthesis? |
the manufacture of proteins. 1) transcription 2) translation |
|
|
where does transcription take place? |
the nucleus |
|
|
what is required for a protein to be made? |
copy of the gene coding |
|
|
what is the copy made from |
nucleic acid - ribonucleic acid (RNA)
|
|
|
what does the RNA do after the copy
|
leave the nucleus carrying the information to the cytoplasm. where it is used in the manufacture of proteins
|
|
|
where does the original gene go?
|
stays in the cytoplasm
|
|
|
what is the difference between DNA AND RNA
|
RNA: Singled stranded polynucleotide made out of ribonucleic acid nucleotides. contain a ribose sugar and not deoxiribose. also RNA never contains thymine, instead its uracil. |
|
|
why does RNA look double stranded
|
Rna molecules fold back on itself and complimentary base pairs pair with each other.
|
|
|
What is MRNA, and whys it called this?
|
the MRNA made in the nucleus, because it carries the code form the Nucleus to the cytoplasm.
|
|
|
What is translation
|
the correct sequence of amino acids join together
|
|
|
What is the enzyme that attaches to the DNA |
DNA polymerise
|
|
|
what happens to the hydrogen bonds and d between pairs, and DNA?
|
break, and one strand DNA unwinds
|
|
|
what strand unwinds?
|
The template strand
|
|
|
what does the Template strand become when transcribed
|
mRNA molecule with the same base sequence as the DNA coding strand. |
|
|
How does this happen |
the two strands align, phospodiester bonds form to produce an MRNA molecule.
|
|
|
due to complimentary base pairing, what does the order of bases determine?
|
the order of bases on MRNA
|
