Intermolecular attractions between polar molecules are a. Hydrophobic interactions
b. Hydrogen bonds
c. James bonds
d. lonic bonds

Answers

Answer 1

Answer:

Answer:

Hydrogen bonds

Explanation:

Polar molecules are slightly charged (positive or negative). Water is an example of a polar molecule. It has a slightly positive charge toward its hydrogen end, and a slightly negative charge toward its oxygen end. In the water molecule, the hydrogen on one molecule (+) is attracted to the oxygen of a neighboring molecule (-) and thus the two water molecules are kept together. This kind of bond between two molecules is called a hydrogen bond.

How does the ribosome know which protein to make?

Answers

Messenger RNA (mRNA) molecules are long strands of RNA nucleotides that directribosomes to make proteins. They travel from the nucleus to the ribosome. Ribosomal RNA (rRNA) molecules make up part of the ribosomes of the cell in the cytoplasm. Transfer RNA (tRNA) molecules transport amino acids to the ribosomes.

"Transcribe the complementary RNA strand."

Answers

Answer:

The correct order would be:

b. "Unwind the DNA molecule near the promoter."

d. "Transcribe the complementary RNA strand."

c. "Exit the nucleus to the cytoplasm."

a. "Combine the mRNA strand with a ribosome and a tRNA carrying a methionine."

The given order is according to the central dogma of a cell. According to central dogma DNA is first transcribed into mRNA which is then moved out of nucleus (in eukaryotic cells).

For transcription, the DNA is unwind near the promoter region where transcription factors and RNA polymerase binds the template strand. It then make mRNA which is moved out of the nucleus.

The mRNA then is translated with the help of ribosome and tRNA. The start codon in mRNA usually codes for methionine due to which tRNA carrying methionine recognises the start codon and initiate the process of translation.
