Ksju [112]

Answer:

In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.

Explanation:

Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.

The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.

In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

G            C

For this reason:

Which of the following would NOT be a constituent of a plasma membrane? Select one: a. messenger RNA b. phospholipids c. glycopr
Katyanochek1 [597]

Answer:

The correct answer is a. messenger RNA

Explanation:

The plasma membrane mainly contains lipids, proteins, and carbohydrates. Phospholipids make the bilayer of the plasma membrane. Carbohydrates can be found attached to proteins and lipids.  

The carbohydrates that are attached to lipids are called phospholipids and those with proteins are called glycoproteins. mRNA is the molecule which is not the part of the plasma membrane. mRNA is produced in the nucleus through the transcription process and is responsible for proteins formation.

So phospholipids, glycolipids, and glycoproteins are the part of the plasma membrane but not messenger RNA.
