Answer:
5= mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
Answer:
The correct option is A. The lipids, because they are responsible for long-term energy storage.
Explanation:
The bodies of organisms are made up of different organic molecules known as biological macromolecules, each specialized to perform unique functions. For example, nucleotides are biological macromolecules made up of nucleotides. The function of nucleotides is to store the genetic information of an organism.
Lipids are macromolecules which are made from fatty acids and glycerol. The function of lipids is to store long- term energy for an organism. Hence, the biology student listed the wrong function for lipids.
Answer:
0.0139- frequency of heterozygotes in the population
Explanation:
Let q to the power of 2 represents the frequency of the homozygous recessive (aa) = 1/20000 = 0.00005
This, q = √q^2 = √0.00005 = 0.007
Since p + q = 1
p = 1 - 0.007 = 0.993
Using the formula: p^2 + 2pq + q^2
Where 2pq represents the frequency of the heterozygotes, thing we have
2 x 0.007 x 0.993
= 0.0139
Answer:
C) DNA produces messenger RNA, also called mRNA.
Explanation:
During transcription DNA is used as a template to make RNA. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.
