dna binding proteins in prokaryotes regulate genes by contr
how are prokaryotic genes regulated
200
messenger RNA
What is MRNA
200
a sequence of genes
What is a genetic code?
200
often produce proteins with new or altered functions that can be useful to organisms in different or changing environments
how can mutations be helful
300
1. sugar in RNA is ribose instead of deoxyribose 2. RNA is single stranded, DNA is double stranded 3. RNA contain uracil instead of thymine
What are 1 of the 3 differences between RNA and DNA
300
read by three letters at a time
how is the genetic code read
300
the effects of mutations on genes vary widely. some have little or no effect, and some produce beneficial variations.
how do mutations affect genes
400
in transcription, segments of DNA serve as templates to produce complementary RNA molecules
How does the cell make RNA
400
ribosomes use a sequence of codons in MRNA to assemble amino acids into polypeptide chains
What role does the ribosome play in assembling proteins
400
some cancers are cause by mutations, and you can also have learning disabilities
What are harmful effects of mutations
500
it carries amino acids to the ribosomes and matches them to coded mrna message.
What does TRNA do
500
the central dogma of molecular biology is that information is transferred from DNA to RNA to proteins
