|
Three consecutive bases on the DNA strand is called a ?/?
|
triplet/codon
|
|
|
When the triplet code is transcribed and translated, it dictates the type and order of amino acids in a ? chain
|
polypeptide
|
|
|
A proteins ? structure determines its characteristic shape and function.
|
primary
|
|
|
Proteins ultimately determine ?
|
phenotype
|
|
|
DNA is mainly a blueprint that ells the cell which kinds of ? and ? to make and how to make them.
|
proteins
RNA |
|
|
The major participants in transcription and translation are ?,?
|
mRNA
tRNA |
|
|
? are considered the "Tools" in the cell's assembly line.
|
RNA's
|
|
|
RNA differs from DNA in that it is a ? stranded molecule it contains ? instead of thymine and the sugar ?
|
single
uracil ribose |
|
|
Only ? is translated into a protein molecule
|
mRNA
|
|
|
? contains codes for sequence of amino acids in protein
|
mRNA
|
|
|
The function of mRNA in the cell is to carry the DNA master code to the ?
|
ribosome
|
|
|
The function of tRNA is to carry ? to ribosomes during translation.
|
amino acids
|
|
|
rRNA contains codes for several large rRNA ?
|
molecules
|
|
|
The function of rRNA in a cell is to form the ? part of the ribosome and participate in ? synthesis.
|
larger/major
protein |
|
|
RNA ? contain codes for a RNA sequence that can begin DNA replication.
|
primers
|
|
|
The function of RNA polymerase in a cell is to place a primer strand for ?
|
DNA polymerase III
|
|
|
mRNA is a ? of a structural gene or genes in the DNA.
|
transcript/copy
|
|
|
The message of the transcribed mRNA is later read as a series of triplets known as ?
|
codons
|
|
|
tRNA is a copy of a specific region of ?
|
DNA
|
|
|
tRNA contains sequences of ? that form H bonds with complementary sections of the same tRNA strand and this gives the tRNA molecule the ? structure it is known for
|
bases
cloverleaf |
|
|
The bottom loop of the cloverleaf tRNA exposes a triplet known as the ? that designates the specificity of the tRNA and complements mRNA's codons.
|
anti-codon
|
|
|
For each of the 20 amino acids there is alt least one specialized type of ? to carry it to the ribosome.
|
tRNA
|
|
|
Ribosomes are mobile molecular factories for ?
|
translation
|
|
|
The prokaryotic ribosome is ? in size and is composed of tightly packed ? and protein
|
rRNA
|
|
|
The rRNA component is a long ? molecule
|
ss-polynucleotide
|
|
|
The interactions of proteins and rRNA create the two ? of the ribosome that engage in the final translation of the genetic code.
|
subunits
|
|
|
The second stage of gene expression is ?
|
translation
|
|
|
The first stage of gene expression is ?
|
transcription
|
|
|
All of the elements needed to synthesize a protein are brought together on the ? for protein synthesis.
