\
D- all of the above
15
New cards
15- results of mitosis

\
\
À-Formation of 2 cells having 46 chromosomes identical to the OG
16
New cards
16- Which clues in à microscopic observation show cancer

\
\
\
B- large variably shaped nuclei
17

17- what mutation is illustrated 

\
\
\

21-translation occurs innthe

\
\
\
Cytoplasm
22
New cards
22- the stronger allele as the __ gene and the weaker allele is known as the ___ gene

\
\
\
Dominant and recessive
23
New cards
23- sickle cell anemia need two recessive alleles. If à person is heterozygous and has à child with à homozygous recessive

\
\
\
50%
24
New cards
24- which structure is labled

\
\
\
A- Q arms
25
New cards
25- restriction enzymes are used to cut dna at specific places

\
\
\
TRUE
26
New cards
26-

Deletion →

Inversion →

Duplication →

Insertion →

Translocation →

\
\
**B C D E A**
27
New cards
27- explain why mutation doesnt make amino acids

\
insertion = 4 letters which means no letter bc à codon, 3 equal an amino acid and one letter left oer.

\
28
New cards
28- non disjunction in meiosis

\
\
non-disjunction is when this process of separation of chromatids (mitosis) and homologous chromosomes (meiosis) fails to occur.
29
New cards
29- step of chromosome 

\
Step 1 - add cell sample

2-culture

3-arrest

4-swell and drop cells

5- stain with dye and observe
