An ionic bond is a complete transfer of electrons from one atom to another. This generally happens between atoms that have opposite electronegativity. This means one has very few atoms in their outer shell, while the other has many. A common example of an ionic bond is that of salt, with Na and Cl. Sodium has one electron in its outer shell, in which it transfers to chloride to make an ionic bond.

Ionic bonds are usually found in dry forms such as salts and are found in compounds throughout the human body. Ionic compounds are generally water soluble.
DNA - As you recall, DNA is formed in the shape of a double helix. The double strands of DNA are held together by hydrogen bonds. Each single strand has a backbone made of sugar and phosphate, as well as either a purine (adenine or guanine) or pyrimidine (cytosine or thymine). Each purine is connected to a pyrimidine through a hydrogen bond, giving the double DNA strand strength, and flexibility. This bond holds the two sides of DNA together, each bond contributing to the overall strength of DNA. When DNA is replicated, special enzymes known as DNA helicase "unzip" DNA and these bonds are broken so the two strands can be individually replicated.

11. Fill in the blanks to describe the similarities between transcription and DNA

Licemer1 [7]

Answer:

See the answer below

Explanation:

Both transcription and DNA replication produce nucleic acids which are polymers of (C, G, A, and T or U). Both processes depend on an enzyme which adds one nucleotide at a time.

To determine which nucleotide is added next, both transcription and DNA replication use the nucleotide sequence in a template DNA strand and the base pairing rules.

Transcription is a process through which RNA is synthesized using a DNA template. An enzyme known as RNA polymerase adds nucleotide bases to grow the RNA strand.

Replication is a process during which DNA makes a copy of itself. The double helix unwinds and each strand is used as a template to make a new strand. An enzyme known as DNA polymerase adds nucleotide bases to grow the new strands.

In both transcription and replication process, the nucleotide sequence of the template DNA strand determines the which nucleotide will be added to the new RNA and DNA strands being synthesized according to the base pairing rule. Purine bases always pair with pyrimidine bases and more specifically, cytosine always pair with guanine while adenine always pair with thymine (uracil in RNA).

A trait, such as height, has high heritability because much of the variation between individuals is the result of genetic variat

Len [333]

This is because the traits like height, are influenced by environmental conditions around the individual. For example, there are two children born to same mother. But one is given best facilities, nutrition and care, whereas other one is brought up by a poor family, which hardly get good food to eat. His condition is much worse than the first case. In such a situation, the former child will grow up healthy and fit, and will have more height than the later one. Although, both got genes from same parent, but the environmental conditions influenced the expression of those genes differently.
