Answer:

A, B, E

Explanation:

The guard cells block water loss (transpiration) when the cells are turgid. To become flaccid, the cells must lose water. This is accomplished when the surrounding cells accumulate K+ making them hypertonic compared to the guard cells. The guard cells then lose water via osmosis.

A toxicity of folate can disguise a deficiency of which nutrient, resulting in nerve damage?

Ket [755]

Large dose of folate increase the symptom of vitamin B12 deficiency . the vitamin B12 deficiency can lead to permanent damage of the spinal cord nerves and brain.

It can cause severe birth defects which is called neural tube defects. this defects include spinal, pifida . folate deficiency can also increase your chance of placental abrupt ion is a condition in which placental separate from uterus.

High dose of folate typically be remedied by taking supplement of both folic acid and vitamin B12. vitamin B12 works closely with vitamin B9 also called folic and folate acid which is help to make red blood cells and iron work better in our body.

Complete question:

A gene on strand of DNA has the following nucleotide sequence: CCCAAGTGG

A) GGG UUC ACC

B) CCC AAG TGG

C) GGG TTC ACC

D) UUU CCC AGA

Explanation:

What are the mRNA triplets coded for from this gene?

A) GGG UUC ACC

RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis. Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.
