biomed unit 2.2

1-WHAT STAGE OF MITOSIS involves the chromatids being actively torn apart

\
\
\

Anaphase

2- What is one mark of cells that have escaped cells cycle

\
\
\

>D is à and c only

Disorganized growth and weird nuclei

3- copying of dna into single strand molecules aka mrna in the nucleus

\
\
\
\

Transcription

\
\
4-whta proces joins amino acids together to make an polypeptide chain

\
\
\

>translation

5- what structure allowst rnas to bind to m RNAs to make à string of amino acids

\
\
\

Ribosomes

6- what autosomal dominant begnin condition that includes cafe ole spots and lychee nodes in the eye reults in à mutation

\
\

Neurofibromatosis

\
7- meiosis results in a

\
\
\

4 haploid daughter cells

8- determine this karyotype 

\
\
\

Turners syndrome

9- what mutation when one portion of chromosome is wrapped by another form of à chromosome.

\
\

D- translocation

10- which term describes the traits an organism has

\
\
\

Phenotype

11-principle of probqbliklity can be used to determine

\
\
\

D-Determine genetic outcomes for offsprings

12- homogenous tall GG and homogenous small Gg

\
\
\

Probability of being tall is 100%

13-

\
\
\

D- all expected to be tall

14-how can chromosomes be matched together for à karyotype

\
\
\

D- all of the above

15- results of mitosis

\
\

À-Formation of 2 cells having 46 chromosomes identical to the OG

16- Which clues in à microscopic observation show cancer

\
\
\

B- large variably shaped nuclei

17- what mutation is illustrated 

\
\
\

B- insertion

18- what does MRI stand for

\
\
\

Magnetic resonance imaging

19- somatic cells refer to organisms that have membrane boundorganelles

\
\
\

false

20- disease caused when uncontrollable cell divide and spread into other tissues

\
\
\

cancer

21-translation occurs innthe

\
\
\

Cytoplasm

22- the stronger allele as the __ gene and the weaker allele is known as the ___ gene

\
\
\

Dominant and recessive

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

\
\
\

50%

24- which structure is labled

\
\
\

A- Q arms

25- restriction enzymes are used to cut dna at specific places

\
\
\

TRUE

26-

Deletion →

Inversion →

Duplication →

Insertion →

Translocation →

\
\

**B C D E A**

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- non disjunction in meiosis

\
\

non-disjunction is when this process of separation of chromatids (mitosis) and homologous chromosomes (meiosis) fails to occur.

29- step of chromosome 

\

Step 1 - add cell sample

2-culture

3-arrest

4-swell and drop cells

5- stain with dye and observe
