DNA, RNA and Protein synthesis (Part 3) Flashcards
1
Q
Gene
A
Sequence of bases in a DNA molecule that carries the instructions for making a simple protein
2
Q
Where are proteins made
A
In the cytoplasm by ribosomes
3
Q
Transcription
A
Producing an RNA copy of DNA (in nucleus)
4
Q
Translation
A
Converting a sequence of bases from RNA into a sequence of amino acids to form a protein
5
Q
RNA
A
RiboNucleic Acid
6
Q
DNA and RNA differneces
A
DNA sugar in nucleotides - deoxyribose Double stranded Four bases - A, C G and T Remains in the nucleus
RNA Sugar in nucleotides - Ribose Single stranded Four bases - A, C, G and U Made in the nucleus, found in cytoplasm
7
Q
Functions of RNA
A
mRNA
tRNA
rRNA
8
Q
mRNA (messenger)
A
Has a sequence of bases used by ribosomes to produce a sequence of amino acids (forming a protein)
9
Q
tRNA (transfer)
A
Links sets of three bases on mRNA strands (called codons and triplets) with the specific amino acid they code for
10
Q
rRNA (ribosomal)
A
What ribosomes are composed of (along with protein)
