DNA
DNA is copied during a process called
replication
Unlike DNA, RNA contains what base?
Uracil
How many codons are needed to specify for 6 amino acids?
6
Genes contain instructions for assembling
A mutation that involves a single nucleotide is called a(n)
point mutation
In eukaryotes, DNA is found
in the nucleus
RNA contains what type of sugar
ribose
Which type of RNA functions as a blueprint or disposable copy of the genetic code?
mRNA
________ is a single strand of nucleic acids
RNA
Accoring to the principle of ______________, hydrogen bonds can only form between A and T and C and G in DNA.
base pairing
What enzyme is involved in DNA replication?
DNA polymerase
What are RNA molecules formed?
in the nucleus
What RNA molecule carries the amino acids?
tRNA
What are the base pairs for DNA? RNA?
DNA:
A=T
C=G
RNA:
A=U
C=G
How many bases are read at a time when reading a codon?
3 bases at a time
What is the result of DNA replication? specifically
2 DNA molecules each with one original strand and one new strand.
What is (are) the type(s) of RNA involved in protein synthesis?
mRNA- messenger RNA
rRNA- ribosomal RNA
tRNA- transfer RNA
What happens during the process of translation?
mRNA is used to produce proteins/ mRNA is read, each codon codes for a specific amino acid
What does the central dogma of molecular biology state?
DNA is transcribed into RNA which is then translated into proteins.
genetic information flows from DNA to RNA to Proteins
The original strand of DNA is CCA ATG what is the complimentary RNA strand?
GGUUAC
Give and example of what would be contained in a nucleotide found in DNA (all 3 parts)
Example: deoxyribose + phosphate group + adenine
If given this strand of mRNA codons- AUG CUU AGC, what would be the anitcodon used by tRNA?
UAC GAA UCG
Using your codon(s) chart what is the codon specified for Histidine
CAC or CAU
What are the major differences between DNA and RNA
RNA has ribose/ DNA has deoxyribose
RNA is single stranded/ DNA is double stranded
RNA has Uracil/ DNA has Thymine
Explain what a start and stop codon is
Start codons start the process of translation were Stop codons stop the process of translation
