What is a ribosome?
What is cell organelle consisting of RNA and protein found in the cytoplasm
100
What is transcription?
What is the synthesis of RNA molecule on a DNA template.
100
can mutations have a positive affect?
yes they can, they can have both good and bad affects
100
an expressed gene
codes for one amino acid
100
The process by which the genetic code of DNA is copied into a strand of RNA is called.
What is transcription
200
where does the mRNA get transcribed?
in the nucleus.
200
What is Translation?
What is process by which the sequence of bases of an mRNA is converted into the sequence of amino acids of a protein.
200
what are the four main mutations?
insertions and deletions, spontaneous and induced, inversions, and point mutations.
200
what is a homeobox gene?
they code for transcription factors that activate other genes.
200
what does RNA stand for
Ribonucleicacid
300
What is a codon?
the three letter "word" or every three bases in the mRNA
300
transcribe CAGTAT
GTCATA
300
what is meant by the term cell specialization?
cell specialization just means that each cell is specialized in what it does.
300
Describe each of the three processes of RNA
MRNA- copies the recipie of DNA TRNA- translates translates the DNA code RNA- makes copies of the DNA in the nucleus
400
what is the genetic code?
a line of bases which is used to form amino acids
400
how does deletion mutations differ from substitution deletions.
deletions delete a code and substitution adds an extra one in.
400
a group of genes that are regulated together is called
What is a operon
