Answer:
1. CGAGGTT → CGTT (Deletion)
2. ATTCGG → ATTCGGATTCGG (Duplication)
3. CTTAAT → TAATTC (Inversion)
4. CTTAAT → CTTAACGCT (Insertion)
5. CGAT → CTAT (Substitution)
6. CCGGTT + TTAGGC = CCGTTA + GTTGGC (Translocation)
Explanation:
1. CGAGGTT → CGTT (Deletion) ---- This is called deletion because it involves the removal of 3 base pairs (AGG) from the DNA sequence.
2. ATTCGG → ATTCGGATTCGG (Duplication) ---- In this case, the particular sequence (ATTCGG) is copied again or duplicated.
3. CTTAAT → TAATTC (Inversion)----- This is called inversion mutation because the DNA sequence breaks off and is reattached but this time in a reverse order i.e. CTT becomes TTC, placing the last base first and the first base last.
4. CTTAAT → CTTAACGCT (Insertion) ------ This is called insertion mutation because it involves the addition of extra base pairs (CGC) into the sequence. The Insertion occurs between the last A and T nucleotide.
5. CGAT → CTAT (Substitution) ----- This is called substitution because Guanine base is replaced by Thymine in the DNA sequence. It is specifically called a transversion substitution because a purine (Guanine) is replaced by a pyrimidine (Thymine). It is called a point mutation because it involves a single base.
6. CCGGTT + TTAGGC = CCGTTA + GTTGGC (Translocation) ----- in this case, CCGGTT and TTAGGC are sequences on different chromosomes. Portions of sequence on the first chromosome (GTT) and second chromosome (TTA) breaks off and gets reattached/exchanged in each other i.e. the first chromosome gets TTA while the second gets GTT. This kind of mutation is called translocation.
Answer:
The cutaneous membrane is made of a simple columnar epithelium
Explanation:
Cutaneous membrane is the membrane of the skin. This membrane protects the skin from the physical and chemical damage.
Cutaneous membrane is present on skin and exposed to the external environment. This membrane is made of stratified squamous epithelium and keratinized and consist of the underlying layer of dermis. Hence, the membrane is not made upof simple columnar epithelium tissue.
Thus, the correct answer is option (3).
The answer is bladder
The bladder stores urine and when the brain signals to release (when we have to go pee) it releases the urine through the urethra. The answer is not kidney because it doesn’t STORE the urine it filters waste and toxins in the body into the urine to be released from the body, the actual bladder itself is the organ that stores the urine in the body.
i have the chart for all of the phases.
answer:
interphase and prophase have the most phases
interphase: 20
prophase; 10
metaphase; 3
anaphase; 2
telaphase; 1
divide each on by 36.
