DNA structure
What pairs with G?
In DNA G always Pairs with C
Transcript STARTS with what molecule?
DNA
what is an anticodon
a sequence of 3 nitrogen bases on the tRna to match mRNA
What is the start Codon of a Protein ?
the start of codon of a protein is AUG
Where are codons found?
Codons are found in mRNA
What is a Double Helix?
The double helix is a description of the molecular shape of a double-stranded DNA molecule
Transcript ENDS with what molecule?
mRNA
what is the Ribosome
the structure that holds the mRNA during translation
What does protein require?
Protein require DNA,mRNA and tRNA
What is an Anticodon
an anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence.
What is nucleotide?
Nucleotides are organic molecules consisting of a nucleoside and a phosphate.
What does it mean to Transcribe?
To re-write or copy.
What is Codon?
a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule
What are proteins?
Answer::Proteins are made up of a chain of amino acids,monomers and then formed at the ribosomes
Why is the Anticodon important?
Anticodons are found on molecules of tRNA. Their function is to base pair with the codon on a strand of mRNA during translation
What are the 3 Components of Nucleotide?
Sugar , Phosphate, Nitrogen Base
What are A-U and C-G
The 4 bases that are used in RNA
What is tRNA?
is a small RNA molecule that participates in protein synthesis
What are the two parts of protein synthesis called?
transcription and translation
Why do we use genetic code?
The genetic code is the set of rules used by living cells to translate information encoded within genetic material (DNA or mRNA sequences of nucleotide triplets
what ae the 4 bases of Dna
Adenine
Thymine
Guanine
Cytosine
What is mRNA
The type of RNA that is formed during transcription
What is mRNA ?
messenger RNA, which is the molecule that essentially puts DNA instructions into action
What are amino acids?
They are building blocks of proteins
What mrna codons can cause a stop?
A stop codon is a trinucleotide sequence within a messenger RNA (mRNA) molecule that signals a halt to protein synthesi
