To protect the mRNA from
destruction by cytoplasmic enzymes,
it needs…

40 Transcription and RNA
Processing
Why is mRNA at the ribosome
shorter than it was in the nucleus?
40 Transcription and RNA
Processing
RNA splicing– introns are removed
and exons are pasted together.

To begin transcription, the TATA
box must be bound by…

The genetic code consists of…

Translation and

Codons (3 nucleotide sequences
on mRNA)
20
Translation and Genetic Code
What is translation?
20
Translation and Genetic
Code
Conversion of nucleic acid
language to amino acid language
to build a protein
30
Translation and Genetic
Code
What does tRNA do in translation?
30
Translation and Genetic
Code
Joins to a specific amino acid and
transfer it by matching its
anticodon to the codon on mRNA
at the ribosome
40
Translation and Genetic
Code
What happens during initiation of
translation?
40
Translation and
Genetic Code
mRNA joins with the small
ribosomal subunit, which is then
joined by a tRNA, and then joined
by the large ribosomal subunit.
50
Translation and
Genetic Code
Why is it significant that there are
64 codons for 20 amino acids?
50
Translation and Genetic
Code
Mutations can still occur with
potentially no noticeable effect
on the phenotype.

More Translation
and Mutations
In terms of
transcription and
translation, how does
genotype determine
phenotype?
More Translation
50 and Mutations
*the information from the gene
on DNA that was inherited from
parents is the genotype. It is
transcribed onto mRNA, and
eventually translated into a
protein. The protein is the
phenotype (expression of the
genotype)

Since each pair of alleles
segregate separately from
other pairs of alleles, Mendel

Assortment

homologous chromosome
random sorting during
metaphase 1 of meiosis.

Because alleles separate when
homologous chromosomes
split in anaphase 1 of meiosis,
this supports Mendel’s…

Q: if both a bear in Yosemite and one in
Alaska fall into the water
which one disolves faster?
A: The one in Alaska because it is

dihybrid cross between
parents heterozygous for

what kind of phenotypic
ratio?
