Answer:
The correct answer is "short RNA primers; Okazaki fragments".
Explanation:
The missing information of this question is as follows:
"Replication of the lagging strand of dna is accomplished by repeatedly making __________ followed by 1,000-2,000 nucleotide segments called __________"
The correct answer is "short RNA primers; Okazaki fragments".
DNA replication always occurs from 5' to the 3' end, in what is known as the directionality or the end-to-end chemical orientation in molecular biology. This fact makes difficult the synthesis of the lagging strand of DNA. In order to achieve this short RNA primers are bound to segments of DNA (serving as the 5' end available for the DNA polymerase to synthesize), which leads to the discontinuous synthesis of Okazaki fragments that are later linked together by the enzyme DNA ligase.
Answer:
Answer is A. Two hydrogen atoms join together to form a molecule of hydrogen gas.
Explanation:
The electromagnetic attraction existing between hydrogen and other electronegative atom, such as nitrogen or oxygen, is known as hydrogen bond. It can also be explained as the electromagnetic attraction occurring when hydrogen binds to a higher or larger atom such as nitrogen.
Note that , the bond existing between two hydrogen atoms resulting in the formation of a molecule of hydrogen gas is covalent bond. Covalent bond can simply be explained as the sharing of electrons.
Answer:
Matter in an ecosystem:
- must be continuously replenished
- is recycled and reused
- is returned to the earth by decomposers
The
most important thing to prepare for a storm is knowing
were to go in case you need to evacuate. If the later is not a
possibility then create
and practice a plan of action for you and your family and build and
emergency kit with first-aid supplies, water and nonperishable foods.
After
that
you can focus on identifying the safest place in your house,
establish an emergency communication channel with your family and
reinforce the roof, windows and doors. <span>Secure
the heavy furniture to avoid accidents and move it away from door and
