how is dna similar to rna
they both help create proteins
they both help create genes
they both make ribosomes
they both are make our of ribose
how is RNA and DNA different
RNA is made of ribose when DNA is made of deoxyribose
DNA has a double helix when RNA is a single helix
one of RNA bases is uracil and one of DNA bases is thymine
they both have thymine base
what is the complementary strand of RNA to
AGCCUUAGGCA
UCGGAAUCCGA
ABCDEFGHI
TCGGAATCCGA
CCGTAATGAC
What is the complementary strand of DNA to
ATTCGGATCGATCA
TAAGCCTAGCTAGT
ABCDEFGHIJK
UAAGCCUAGCUAG
TGCATTGCCCATGA
How many amino acids do you get from the following strand
AGCGCCUUAUCG
4 AMINO ACIDS
MANY AMINO ACIDS ARE CODED FROM MORE THAN ONE CODON
1 AMINO ACID
12 AMINO ACIDS
What is an anticodon
recognize a specific codon
read a specific codon
get ride of codons
is the opposite of a codon
where is a anti codon found
on DNA
on RNA
on the cell membrane
in the vacuole
what is there purpose of tRNA
to translate a codon into a amino acid
to attach to an amino acid
to move amino acids
to change the code of an amino acid
what is a translation and where does it take place
takes place in the nucleus
takes place in the ribosome
converts mRNA messages into proteins
converts proteins into amino acids
what enzymes are involved in transcription
RNA polymers
helicase
primase
ligase
transferases
steps of transcription
1. RNA polymers identifies gene to be copied
2. DNA unzips
3. RNA nucleotides move to one side
4. complemetry strand of RNA is made
5. mrna detaches dna connects
dna unzips
then rna is reconnected
rna unzips and dna is reconected
what is transcription? where does it take place? what is the purpose?
transcription is the process that converts the DNA message into an immediate molecule RNA
it takes place in the nucleus
the purpose is to make new strands of DNA
it takes place in the ribosome
the purpose is to make new RNA
What does mRNA DO
acts as a messenger between DNA and ribosomes
transfers the code of proteins
makes parts of ribose
what does tRNA do
makes parts of ribose
transfers the code of proteins
acts as messenger between DNA and ribosomes.
what does rRNA do
acts as messenger between DNA and ribosomes.
transfers the code of proteins
makes parts of ribose
