MAking an exact copy of itself
An enzyme that forms new strands of DNA.
Something that directs the construction of something else.
A DNA strand acts a template for the formation of a new complementary strand.
Non-sex body cell
One Chromosome of a pair in the body.
The two chromosomes that make up a pair.
a.k.a. 1a from dad 2a from mom.
Cells that have two sets of chromosomes.
The portions of DNA that carry code for protein synthesis.
The sugar in RNA
The nitrogen base in RNA as opposed to thymine in DNA.
On strand of nitrogen bases
RNA is single-stranded
Forming new RNA from DNA.
RNA produces new proteins.
Nucleotides -----> Amino Acids
THe enzyme from DNA that creates a new RNA,
Carries information for protein synthesis,
in the form of a nucleotide sequence.
Interacts with the cell's ribosomes to make them functional.
rRNA is the catalyst for protein synthesis;
if there's no rRNA the the ribosomes don't work.
Carries amino acids from the cytoplasm to the ribosomes during protein synthesis.
A sequence of three amino acids.
The dictionary for protein translation:
A sequence read without repeating.
AUG GCA CGA
A special region on the tRNA that can base pair with the codons on mRNA.
The anticodon must be complementary to base pair.
THe area on the tRNA where the anticodons are.
The organelle that synthesizes protein.
mRNA binds to the ribosomes, and tRNA carries amino acids to it.
The ribosome has a A-site (Amino)
and a P-site (Peptide).
Growing peptide is attached to the ribosome at the P-site.
The next Amino acid is continually added to the A-site.
