The answer to the question is D
Answer:
D) Yes, it is important that the single-stranded DNA have 3′ ends, so resection must occur in the 5′ to 3′ direction.
Explanation:
During homologous recombination, the exonucleases remove nucleotides from the free 5' ends of the DNA at the double-stranded breaks to create a double-strand gap.
Removal of more nucleotides from the free 5' ends creates 3' single-strand extension which in turn invades the intact homolog and pairs with its complementary sequence of the DNA. The invaded free 3' end is then extended by DNA polymerase to give rise to Holiday junctions.
If the resection occurs in the opposite direction and creates overhangs with free 5' ends, the free 3' ends would not be available to serve as a primer to facilitate the replication.
Magnetic is the answer, hope this helps!
Answer:
Teres major muscle
Explanation: It is among scapulohumeral muscles. It is attached to the humerus and the scapula. It is positioned above the latissimus dorsi muscle. Teres major muscle is located underside the upper arm, between the elbow and the shoulder. It is flat in shape. It is adductor of the humerus, extend the humerus from flex position, stabilise the humeral head in glenoid cavity.
