The anticodon for the triplet UCA is
AGU
Chromosomes consist of ________ and ________.
DNA; proteins
The mRNA sequence that is complementary to the sequence ATC on DNA is
UAG
The complex structures of DNA and protein found in the cell nucleus are
chromatin and histones.
The triplet codes needed to specify a specific polypeptide chain are found in the
gene.
The functional units of DNA that contain the instructions for making one or more proteins are
genes
The components of ribosomes are formed within
nucleoli
Histones are found in
nucleosomes.
Most of a cell's DNA is located in its
nucleus
The control center for cellular operations is the
nucleus
mRNA is needed to synthesize ________ in the cytoplasm.
proteins
As each codon arrives at the active site of a ribosome, it attracts another molecule containing the anticodon. This molecule is called
tRNA
The smallest living unit within the human body is
the cell.
The process of forming mRNA is called
transcription.
The process of protein formation directed by mRNA is called
translation.
