-parital, undirectional transfer of DNA
-ribosomes - Answer -prokaryotic cell
responsible for important energy-conversion reactions in eukaryotes - Answer -
mitochondria
-the process of using DNA to make an mRNA copy of the gene
-occurs in the nucleus
-mRNA polymerase adds bases (A binds with U in this case)
-mRNA enters cytoplasm - Answer -transcription
-the process of using the mRNA copy as a set of instructions to assemble amino acids
into a protein
-mRNA molecue associates with a ribosome
-ribosome moves along the mRNA "reading it" in groups of 3 nucleotides (3 nucleotides
= 1 codon)
-a codon specifies a particular amino acid
, -tRNA carries amino acids to mRNA and ribosome by using its anticodon to find a
matching mRNA codon
-uses mRNA to produce protein
-completed amino acid chain detaches from the ribosome and folds into its 3D shape -
Answer -translation
the RNA copy of an original DNA sequence made during transcription - Answer -mRNA
a type of RNA that transports amino acids to the ribosome during translation - Answer -
tRNA
the part of tRNA molecule that binds to a complementart mRNA codon - Answer -
anticodon

-first part of reproductive tract
-muscular, elastic
-extends to cervix - Answer -vagina
opening to the uterus - Answer -cervix
-located in scrotum
-outside bc they need to be cooler
-responsible for sperm production and testosterone (around 60 days for sperm) -
Answer -testicles
holds the testes - Answer -scrotum
coiled structures that constitute the bulk of the testes and in which sperm develop -
