Optimal activation of transcription of the GAL genes in yeast requires the function of two proteins: Gal4p and Gal11p. Elimination of either protein decreases activation of the GAL promoters. However, inactivation of Gal11p has the additional and dramatic effect of cell lethality. Why might elimination of Gal11p have a greater effect than elimination of Gal4p

Answers

Answer 1

Answer:

Gal4p is a transcription factor that targets specific GAL genes, while Gal11p is a core component of the Mediator complex that plays regulatory roles in the expression of many different genes (class II genes) in eukaryotic organisms

Explanation:

The Gal4 transcription factor is one of the most widely studied eukaryotic transcriptional activators capable of activating the expression of galactose-induced genes. Gal4 is well-known to target specific enzymes involved in galactose metabolism: GAL1, GAL7, and GAL10. On the other hand, Gal11p is a key subunit of the evolutionary conserved Mediator complex that binds to the RNA polymerase II (RNAP II) in order to regulate the transcription of class II genes (i.e., genes transcribed by RNAP II).

Which of the following has not sped up the erosion of wetlands in coastal Louisiana?
A. dredging of thousands of kilometers of canals throughout the wetlands
B. the increase in acidity of the rainwater in the southeastern United States
c. the loss of barrier islands the cost of Louisiana
D. the 2010 Deepwater Horizon well blowout

Answers

Answer: B. the increase in acidity of the rainwater in the southeastern United States

Explanation:

The dredging of thousands of canals throughout the wetlands for easier navigation has sped up the erosion of Louisiana wetlands so option A is false.

The loss of barrier islands on the coast of Louisiana as a result of rising sea levels has also sped up the erosion of the wetlands as they are now more exposed to open water so option C is wrong as well.

The 2010 Deepwater Horizon disaster spilled so much oil that adversely affected the wetlands leading to their erosion so option D is wrong as well.

Option B is therefore right.

During the process of DNA replication, a complementary DNA strand is formed. If the original strand of DNA is 5 ATA GTG CCC AAC GGT 3 which of the following would be the correct complementary DNA strand?
3. ATA GTG CCC AAC GGT 5
3 TAT CAA GGG TTG CCA 5
3 TAT CAC GGG TIG CCAS
3 TAT CAC GGG TTG CCT 5

Answers

Answer:

the third one

Explanation:

DNA replication produces two duplicated semi-conservative daughter strands. The complementary DNA strand of the original sequence will be, TAT CAC GGG TTG CCA. Thus, option c is correct.

What is DNA replication?

DNA replication is the process where the parent DNA strand forms two daughter strands that are semi-conservative and complementary to the DNA molecule. The complementary base pairing rule is used to produce the leading and lagging strand.

The complementary base pairing rule states the bonding between a purine and pyrimidine molecule. Accordingly, adenine base pairs with thymine, and guanine base pairs with cytosine.

Parent strand: 5' ATA GTG CCC AAC GGT 3'

Complementary strand: 3' TAT CAC GGG TTG CCA 5'

Therefore, option c. 3' TAT CAC GGG TTG CCA 5' is the complementary sequence.

A partial DNA sequence for normal hemoglobin and a partial DNA sequence for sickle-cell anemia are shown below. G-G-A-C-T-T-C-T-T Normal hemoglobin G-G-A-C-A-T-C-T-T Sickle-cell anemia Based on the DNA sequences, sickle-cell anemia is caused by A. a sex-linked trait. B. a dominant nucleotide. C. a mutation in the genetic code. D. an incomplete separation of chromosomes.

Answers

Answer:

C. a mutation in the genetic code.

Explanation:

A mutation refers to any change or alteration to the nucleotide sequence of a gene caused by mutagen or mistakes during replication. Depending on the manner of occurrence, mutation can be of different types. In this question, partial DNA sequence for normal hemoglobin is given as: G-G-A-C-T-T-C-T-T while the partial DNA sequence for sickle cell anaemia is given as: G-G-A-C-A-T-C-T-T.

From careful observation of the two two DNA sequences above, it can be realized that a SUBSTITUTION MUTATION from T to A has occurred in the sequence of sickle cell. Note that substitution mutation is the replacement of one base by another in a sequence.

What is the second most abundant element on earth and seems to be very important in biological processes such as oxygen transportation in the body and cellular respiration

Answers

Answer:

iron

Explanation:

Cellular respiration may be defined as the group of metabolic processes as well as reactions which occurs in the cells of the organisms that converts the chemical energy from the oxygen molecules or from nutrients into ATP or adenosine triphosphate and then releases the waste products.

Cell structure: This talks about how the cells look like when viewed. A call contains components such as the nucleus, cytoplasm, cell membrane etc and each has their various functions to ensure the organisms/animals are able to perform various life activities.

Cell function: This on the other hand refers to the various functions which a cell is able to perform and this is dependent on the component in question such as the nucleus which controls cell activities and cytoplasm which provides support and helps to house other organelles.
