DNA and RNA & Protein synthesis
Terms in this set (47)
nitrogen base - a purine
on tRNA, 3 base pairs, complementary base pair to a codon
on mRNA, 3 base pairs, codon codes for an Amino Acid
nitrogen base - pyrimidine
monomer of DNA: nucleotide
found within nucleus
made of sugar phosphate backbone
made of A, T, C, G nitrogen bases
5 carbon sugar, phosphate group
nitrogen base, purine
An ENZYME - unzips the strands of DNA
synthesized discontinuously in short Okazaki fragments
An ENZYME - seals the okazaki fragments "the glue"
type of RNA that is made during transcription, made in nucleus and goes to cytoplasm - its translated into a protein, single stranded
make up the building blocks of DNA and RNA: adenine, guanine, cytosine, thymine and uracil
the monomer of DNA and RNA
short, newly synthesized DNA fragments that are formed on the lagging template strand during DNA replication.
adds the base pairs together
2 rings - guanine and adenine
1 rings - thymine and cytosine
in cytoplasm and responsible for translation by transferring correct base pairs, single stranded and globular
Semi Conservative Replication
1 NEW daughter and 1 OLD parent
nitrogen base - pyrimidine
occurs in the nucleus, A step in protein synthesis where genetic information is copied from DNA to mRNA
A step in protein synthesis where mRNA information is decoded to synthesize proteins
Type of RNA ..located in the cytoplasm and makes up the ribosomes during translation, AA on 3' end, anticodon, single stranded but folded like clover or T
a base pair that replaces thymine in RNA
Region of DNA that signals the beginning of a gene to be transcribed
Region of DNA that signals the end of a gene to be transcribed
Region of protein coding genetic information that is pieced together during RNA splicing
Region of non-protein coding genetic information that is removed during RNA splicing
The editing of the mRNA transcript that occurs after transcription in which introns are removed, occurs in nucleus
First step of transcription where RNA polymerase binds to the promoter region of a gene
Second step of transcription where RNA polymerase copies the gene information into mRNA by pairing A-U and C-G
Third step of transcription where RNA polymerase detaches from the gene and the mRNA strand is released
The codon on mRNA that signals the beginning of a gene to be translated into a protein, AUG = methionine
One of three codons on mRNA that signals the end of a gene to be translated into a protein, UGA, UAA, UAG
DNA's primary function
to hold all genetic material
structure of DNA
double helix (2 strands), backbone of phosphate and deoxyribose sugar, 4 nitrogen bases with hydrogen bonds
structure of RNA
one strand of phosphate and ribose sugar, with 4 nitrogen bases with hydrogen bonds *uracil
During transcription, in what direction is (1) RNA synthesized and (2) the DNA template "read"?
(1) 5'→3'; (2) 3'→5'
RNA primary function
1)Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-base code "words," each of which specifies a particular amino acid.
2) Transfer RNA (tRNA) is the key to deciphering the code words in mRNA.
3) Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes.
the chart with the combinations
multiple codons can code for the same amino acid
An ENZYME- produces primary transcript RNA
Role of proteins? Whats the purpose?
regulate body processes
help w/ immunity
Eukaryotes make this before mRNA
3 processes before mRNA in eukaryotes
1. splicing 2. adding a Poly a tail - add lots of A's to 3' 3. 5' cap - add lots of G's
