Information is encoded in DNA, then copied onto RNA during transcription. Then, ribosomes convert the information carried in RNA into a protein, in the process of translation. Also, A and D could be ruled out because DNA and RNA are solely involved with proteins, but polysacchariades are chains of sugars.

Does exocytosis require energy?

spin [16.1K]

Answer:

There are two types of vesicle transport, endocytosis and exocytosis (illustrated in the Figure below). Both processes are active transport processes, requiring energy. Illustration of the two types of vesicle transport, exocytosis and endocytosis.

Explanation:

So in a simple explanation yes they require energy:)

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for suppor

omeli [17]

Answer:

A. red blood cells containing malaria

Explanation:

Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.

When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.

Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.

A section of the RNA sequence made from a particular gene is shown below.

MA_775_DIABLO [31]

Since UAG is a stop codon, it would introduce an early termination on the translation of the sequence.

Use the double-stranded DNA molecule below to answer the following questions. The first pair of nucleotides (bolded) contains th

krok68 [10]

Answer:

The correct answer is 2. 5'-AUGUCAGGUACGCCACAU-3'

Explanation:

The template strand for transcription is 3'-TACAGTCCATGCGGTGTA-5 and RNA polymerase will add complementary mRNA sequence against this strand in the opposite direction i.e., 5' to 3' direction.

In RNA, A(adenine) makes complementary base pairing with U(uracil), not with T(thymine) and the rest of the base-pairing is same as in DNA. Therefore the correct mRNA produced from the transcription of this DNA molecule by the help of RNA polymerase is 5'-AUGUCAGGUACGCCACAU-3'.

Then this mRNA sequence will be used by ribosomes to synthesize proteins during the translation process.
