DNA replication is when
DNA makes RNA
DNA makes a copy of itself
RNA makes DNA
RNA makes a copy of itself
DNA must _______________ in order to replicate each strand.
close
emerge
unwind
DNA's structure is described as a
single helix
double helix
DNA must replicate in order for
cell replication to take place

A nucleotide is indicated by the letter:
A
B
C
D
This image is a
nucleotide of DNA
nucleotide of RNA
Prove why this image is a nucleotide of DNA
because of its phosphate
because of its nitrogen base
because of its deoxyribose sugar
Which image is of a nucleotide of DNA
Protein synthesis is when
proteins are produced in the mitochondria
proteins are produced in the nucleus
proteins are produced in the ribosome
What are the two processes of protein synthesis in the correct order?
transcription and translation
translation and transcription
transcription and replication
replication and transcription
What happens during transcription?
mRNA transcribes DNA to carry the message to the ribosome
tRNA transcribes DNA to carry the translation to the ribosome
rRNA transcribes DNA to carry the ribosome to the ribosomal
What happens during translation?
tRNA leaves the nucleus, travels to the ribosome, and translates amino acids on mRNA into proteins
mRNA leaves the nucleus, travels to the ribosome, and translates amino acids on tRNA into proteins
mRNA stays in the nucleus, and translates amino acids on tRNA into proteins
tRNA stays in the nucleus, and translates amino acids on mRNA into proteins
