Which event does not take place during interphase?
Dafna1 [17]
The correct answer is "crossing over."

Cellular growth takes place under interphase, specifically under G1 phase of interphase wherein there is increase in cell proteins and structure. Duplication of chromosomes (or DNA synthesis) takes place under interphase, specifically under the S phase of interphase. In the S phase, there is also duplication of organelles. Crossing over takes place under prophase I of meiosis.

A double-stranded molecule of DNA has 80 T nucleotides and 110 G nucleotides. What is the TOTAL number of nucleotides in this mo
MAVERICK [17]

Answer:

380

Explanation:

The mentioned double-stranded DNA has 80 thymine nucleotides. This means that this DNA duplex has a total of 80 adenine bases. Since thymine pairs with adenine, the number of thymine and adenine is equal in a double-stranded DNA. Similarly, the presence of a total of 110 guanine nucleotides in the DNA indicates the fact that it has a total of 110 cytosine nucleotides. So, total number of nucleotides in this DNA double helix would be= 80 A + 80 T + 110 G + 110 C= 80 + 80 + 110 + 110 = 380.

Polymers are formed via dehydration reactions by molecules. Which of the following best describes a dehydration reaction?
netineya [11]

The correct answer is; "Assembling molecules in either hydroxyl or carboxyl functional groups"

Polymers are formed from monomers either by condensation or by addition of monomers.

A polymer is formed by the joining of one or more monomers. This can happen in either of the following ways;

  • condensation
  • addition

Condensation polymerization involves the loss of a small molecule. When the molecule that is lost is water, we can call it dehydration. Loss of molecules does not occur in addition polymerization.

The two monomer molecules that join to yield the polymer by dehydration must have H and OH moieties in suitable positions for dehydration to occur. A typical example is assembling molecules in either hydroxyl or carboxyl functional groups.

For more about condensation polymerization, see
