Unit 1- Chapter 3- RNA, Transcription and Translation- Higher Human Biology
Post- Translational Modifications
3’ end
I am what is determined in a cell by the
sequence of DNA bases in its genes
Messenger RNA (mRNA)
I am the region on a DNA strand that stops a
growing mRNA molecule from growing
anymore
RNA Polymerase
I am the second type of RNA that meets mRNA
at the ribosome, where translation occurs
Primary Transcript of mRNA
I am the name of the region on DNA where
transcription is initiated
Transcription and Translation
I am the name given to non-coding regions on a
DNA strand
Uracil (U)
I am the repeating units that make up a singlestranded RNA
Ribosomes
I am the factors that can affect gene expression
RNA Nucleotides
I am the type of strand that is synthesised from
a DNA strand and carries information to the
Ribosome
Transcription
I am the three parts that make up an RNA
Nucleotide
Promoter Region
I am the name of the enzyme responsible for
transcription
Genotype
I am the end to which RNA polymerase can add
new nucleotides during transcription
I am the two processes involved in gene
expression
Transfer RNA (tRNA)
I am what is determined in a cell by the
proteins that are synthesised when the genes
are expressed
Environmental Factors acting inside and outside
the cell
I am the structure where assembly of amino
acids takes place in a cell
Ribose Sugar, Base and Phosphate Group
I am the name of the process by which a mRNA
strand is synthesised from a section of DNA
Introns
In RNA I am the base that replaces thymine
found in DNA
Exons
I am the name given to coding regions on a
DNA Strand
RNA Splicing
I am the name given to the process of cutting
out introns and putting together exons to form
a mature transcript
Terminator Sequence of Nucleotides
I am the name given to the triplet of bases on a
mRNA strand
Anti-codons
I am the name given to the mRNA strand that
becomes separated from its DNA template
Start Codon
I am what the mRNA codon that codes for the
amino acid Methionine also acts as
I am what mRNA codons that don’t code for an
amino acid act as
Phenotype
Alternative Segments of RNA may be treated as
Exons and Introns
I am the name given to the process by which a
single polypeptide chain may need to be cut by
enzymes to become active
5’ end
Codons
I am the name given to the complementary
triplet of bases found on a tRNA strand
Peptide Bonds
I am the type of bond that forms between
amino acids
Cleavage
I am the reason why different mRNA molecules
are produced from the same primary transcript
Stop Codons
I am the name given to the modification of a
protein by either folding, coiling, cutting or
adding phosphate or carbohydrate groups to
the protein
I am the region that a ribosome must bind to
on a mRNA template so that translation can
begin
