Capping is addition of _____ towards 5' end of hn RNA

• Methyl cytosine

• Methyl guanosine

• Methyl adenosine

• Methyl uridine

RNA must be edited before it can be used to make Proteins, what happens during this editing process?

• A spliceosome cuts out exons, reconnects the introns

• A spliceosome cuts out the introns, reconnects the exons

• A splicesome pairs nucleotides with the DNA base pairs

• The RNA is checked for typos

• Polymerator

The______ region lies towards the 3'end of the coding sequence of DNA since the transcript is made ___.

• Promoter, 5'-3'

• Terminator, 5'-3'

• Promotor, 3'-5'

• Structural genes, 3'-5'

Select the true statement.

• The whole DNA antisense strand is transcribed

• Both sides of the DNA strands are encoded into mRNA.

• The gene section of a DNA antisense strand is transcribed.

• The gene section of the double helix is transcribed.

Which statement is true?

• A gene is expressed all the time.

• All genes in our chromosomes are expressed at the same time frame of life.

• A gene is expressed when needed, otherwise it is 'silent'.

• All genes are expressed all the time.

Select which nitrogenous bases can NOT be found in RNA.

• Adenine

• Thymine

• Uracil

• Cytosine

The difference between DNA code and the epigenome is that the DNA code is

• flexible, while the epigenome is fixed for life
• fixed for life, while the epigenome is flexible
• determined by the environment, while the epigenome is not
• determined by one's stress level, while the epigenome is not
