Double-stranded DNA is a right-handed helix formed by two individual DNA strands aligned in an antiparallel fashion (a right-handed helix, when viewed on end, twists clockwise going away from the viewer). Antiparallel DNA has the two strands organized in the opposite polarity, with one strand oriented in the 5′-3′ direction and the other oriented in the 3′-5′ direction.

The 3' and 5' refer to the carbons on the deoxyribose Hope this helps :)

Messenger RNA carries a(n) ___________ of the DNA’s instructions out of the nucleus to the ___________.
Nitella [24]


messenger RNA  (mRNA) carries a transcript (copy) of the DNA's instructions out of the nucleus  to the cytoplasm where it attaches to a ribosome.

transfer RNA (tRNA) begins to read (translate) the information on the attached mRNA and corresponding to this information, fetches the appropriate amino acids from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are linked into a chain or polymer forming the primary structure of the desired protein.

mamaluj [8]

Coastal erosions affect the development of the Florida peninsula.  

Explanation:

Coastal erosion along the Florida coast is due to rising sea level, natural disasters like frequent storms and hurricanes, numerous navigational inlets and other constructions, and poor developmental plans.

Since the entire stretch of Florida is covered by coastline, coastal erosion is a big threat to people living along its coasts, especially in places like Jacksonville.

Florida is a state which attracts a huge number of tourists mainly due to its coastline which contributed a lot to the state’s economy. With increasing coastal developments, the erosion also increased making it more vulnerable.

Many public and private properties have been eroded due to coastal erosions. Hence sustainable development must be undertaken to protect the coastline as well as develop the state of Florida .
