BIOCHEM C785 EXAM QUESTIONS AND CORRECT
ANSWERS, WITH COMPLETE SOLUTION.
transcription
when DNA info is needed, the cell makes RNA copy of the DNA to send to the rest of
the cell
what are the workhorses of the cell?
proteins
what is the central dogma of molecular biology?
the understand that DNA is used to make RNA and RNA is used to make proteins.
what is nucleic acid made of?
made up of monomers called nucelotides
what are nucleotides made up of?
phosphate, pentose sugar, nitrogen base
Where is DNA located in the cell?
chromosomes in the nucleus
How does transcription begin? (DNA moving to RNA)
RNA polymerase binds to promoter, DNA is transcribed into mRNA, mRNA exits cell
into cytoplasm, attatches to ribosome, RNA message is translated into protein langauge
who discovered DNA?
watson and crick, introducted the double helix structure
What his the human genone project?
the mapping of all human genes
nucleic acids are
polymers of nucleotides
what is nucleotide?
Nitrogen base + sugar (ribose or deoxyribose) and phosphate group
DNA contains which bases?
A, G, C, T
RNA contains which bases?
A, G, C, U
what are the three types of RNA?
messenger RNA, transfer RNA, ribosomal RNA
what are nucleotides linked together by?
phosphodiester bonds between the phosphate of 1 nucleotide and the sugar of another
(outer side)
What kind of bond link together the base pairs?
hydrogen bonds
what does semi-conservative mean?
each copy of DNA contain both a "new" and an "old" strand
what is the process of copying DNA?
replication/ allows each cell to pass on a complete set of DNA to a person
What are the steps of DNA replication?
