Studied by 27 people
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
