babunello [35]

<u>Answer:</u>

CCGAGU

<u>Explanation:</u>

DNA transcription:

DNA transcription is the process through which DNA double helical strand is converted into single stranded RNA molecule.

During transcription two strands of DNA are named differently i.e Template strand and coding strand.

Template strand:

Strand from which RNA is producing is known as template strand while

Coding strand:

The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.

Correct Answer:

Template strand from 5' to 3' reads GGCTCA. and

In this question CCGAGT is coding strand.

RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes

Which of the above molecules would be least soluble in water?<br><br>(See attached image)​
weqwewe [10]

C

Explanation:

Molecule C would be least soluble in water because it is not a polar compound/molecule. It also lacks any unit that can combine with water to form a good hydrogen bond.

  • The general rule of solubility is that like dissolves likes.
  • Polar molecules will only dissolve in polar solvent.
  • Water is a polar solvent with hydrogen bonds in them.
  • Hydrocarbons typically have weak london dispersion forces between them and they are not polar.
  • Other compounds have functional groups that can form hydrogen bond with water.
