Worksheet time: 13mins
The monomers units of DNA and RNA are
amino acids
monosaccharides
nucleotides
fatty acids
The signal that marks the end of a gene and causes transcription to stop is
polymerase
ligase
a terminator
methionine
The RNA codon AUG means
add amino acid methionine
start the protein here
add the amino acid tyrosine
end the polypeptide chain here
Which of the following occurs when RNA polymerase attaches a promoter DNA?
elongation of mRNA
termination of mRNA
initiation of a protein
initiation of mRNA
A gene is
the same as a chromosome
the info for making a polypeptide
made of RNA
made of protein
When RNA is being made, the RNA base ____ always pairs with the base ___ in DNA.
U-T
T-G
U-A
A-U
tRNA plays a role in which of the following ?
picking up the amino acid specified by the anticodon
recognizing the appropriate codons in mRNA
translating codons into amino acids
all of these are correct
Which organelle is the location where protein is made?
Ribosome
Nucleus
Cytoplasm
Nucleotide
During transcription, this type of ribonucleic acid is responsible for copying the DNA and brining it out of the nucleus.
tRNA
mRNA
rRNA
dRNA
What is the purpose of this process?
To translate the genetic code into a specific sequence of amino acids
To synthesize amino acids used to unzip strands of DNA and copy the genetic code
To assemble nucleotides in an mRNA chain along a DNA template
To replicate the DNA of an organism before cell division
The anti-codon
contains a sequence the same as the mRNA codon
contains a sequence complementary to the mRNA codon
contains the base thymine
What is the structure that is labeled by an X?
Anticodon
Amino acid
Codon
Polypeptide
What is the purpose of strand "A"?
For DNA replication
To make more DNA
To serve as a template for the synthesis of mRNA
To carry the genetic information to the cytoplasm
