5´ UTR
Is present in DNA
Is present in RNA
Initiates the RNA synthesis
Initiates the protein synthesis
Is a part of exon 1
DNA acid contains
Ribose
Deoxyribose
Adenine, cytosine, guanine, thymine
Adenine, cytosine, guanine, uracil
Phosphate group
Which elements are necessary for denaturation
DNA polymerase
RNA polymerase
Helicase enzyme
Urea
High temperature (94 C)
Frameshift can be caused by
Insertion of 1 base pare (bp)
Insertion of 3 bp
Deletion of 2 bp
Substitution of 1 bp
Deletion of 5 bp
Mark fragments of the gene which can be found within DNA and after transcription also within RNA transcript
Promoter
Exons
Introns
5´ UTR
3´ UTR
Polymorphisms
Are DNA alterations that cause a disease
Are changes in DNA sequence
It is difficult to distinguish between polymorphism and missense mutations
May result in protein disfunction
Are large genomic deletions
DNA hybridization
Single-stranded DNA probe becomes attached with another singe-stranded DNA sequence
Is one of the steps of protein synthesis
Is the process of transferring of the genetic information from DNA to mRNA
Is the process of transferring of the genetic information from mRNA to protein
It is true that
RNA processing consists of three processes, splicing, cap binding and a poly tail adding
During RNA processing, splicing is the first step of DNA replication
Cap binding, occurs on 3 UTR of the RNA-molecule
During splicing the exons are delated but not introns
During splicing the introns are deleted but not exons
Is it true that
There are only 20 different tRNA particles in humans
Each amino acid is coded by one codon only
Poly-a tail adding occurs in cytoplasm
Somatic mutations can be inherited by next generation
Gremline mutations can be inherited by next generation
Is it true that
RNA is always double-stranded
DNA is more stable than RNA
DNA can be isolated from brain cells
RNA contains sugar ribose
RNA can be isolated from white blood cells
RNA interference
Increase the protein synthesis
Takes place in the nucleus
Inhibits transcription
Can be caused by the enzyme DICER
Inhibits translation
A nonsense mutation generally results in
Translation of incorrect amino acids
Shorter polypeptide
No change in expressed protein
A frameshift
Which one of the following is a function of the plasma membrane
Play a role in protein modification
Plays a role in signal transduction
Forms a selective barrier around the cell
Is the control centre around the cell
What process occur in Golgi apparatus
Transcription
Protein modification
Protein packing
DNA replication
