Imagine you are following a particular tRNA, called tRNAQ, through the process of translation in a eukaryote. Consider the steps of tRNAQ translation. 1. The polypeptide is transferred to tRNAQ. 2. tRNAQ binds the A site of the ribosome. 3. tRNAQ binds the P site of the ribosome. 4. The ribosome shifts, with tRNAQ still bound. 5. tRNAQ binds the E site of the ribosome. In what order does tRNAQ go through the steps listed

Answer 1
Answer:

Answer:

2; 1; 4; 3; 4; 5

Explanation:

A transfer RNA is a small RNA sequence (approximately 75-90 nucleotides in size) that serves as an adaptor molecule in order to link a specific triplet of nucleotides or 'codon' in the messenger RNA (mRNA) with a particular amino acid in the ribosomes during protein synthesis (i.e., during translation). The tRNAs have 1-a trinucleotide region known as the anticodon, which is a sequence complementary to a codon in mRNA, and 2-a region for attaching a particular amino acid. Moreover, a ribosome has three slots for binding tRNAs: A site, P site, and E site. The ribosomal A-site is the first location the t-RNA binds during translation; the P-site is the second binding site for tRNAs; and, finally, the E-site is the third site where deacylated tRNAs bind before their dissociation from the ribosome.

Decomposers

Producers

Heterotrophs

Answers

Decomposers  get nutrients and energy by breaking down dead organisms and animal wastes. Through this process, decomposers releasenutrients, such as carbon and nitrogen, back into the environment. These nutrientsare recycled back into the ecosystem so that the producers can use them.

Translate this sequence from mRNA to protein: AUG CAC UCG

Answers

Answer:

The result of the translation of the mRNA sequence AUG CAC UCG into protein is methionine, histidine and serine.

Explanation:

Messenger RNA (mRNA) is responsible for carrying the sequence of nitrogenous bases of its molecule to the ribosome to be translated into amino acids and synthesize proteins.

Three nucleotides of mRNA form triplets or codons that can encode:

  • The initiation of protein synthesis, with the AUG codon also coding for methionine.
  • Amino acids to be added to the peptide chain.
  • Stopping protein synthesis.

For the mRNA base sequence AUG CAC UCG, the amino acid sequence that corresponds to the synthesized peptide or protein is Met-His-Ser, i.e. methionine, histidine and serine.

The spiral ganglion cells of the inner ear are unipolar.
a. True
b. False

Answers

Answer:

b. False

Explanation:

The spiral ganglion, formed from the primitive otocyst, is located on the cochlea's modulus (axis) and is made up of approximately 35,000 neurons in man. These bipolar neurons are of two types: type I and type II. Its peripheral extensions (dendrites) end in the spiral organ, in contact with the hair cells of which they receive information. Its central extension (axon) ends at the cochlear nuclei of the brainstem.

In Type I diabetes the body cannot make ______ and in Type 2 diabetes the hormone ________ doesn't work properly. (Choose the best option.)
1. Estrogen and insulin
2. Epinephrine and insulin
3. Insulin and glucagon
4. Insulin and insulin

Answers

Answer: 4. Insulin and insulin

Explanation:

Diabetes indicates that the level of glucose, or sugar, is very high in the blood.It occurs when the pancreas doesn't produce enough insulin or when the body doesn't use insulin properly (called insulin resistance). Insuline is a hormone that helps glucose get into the cells to give them energy, and glucose comes from the food and drinks being the main source of energy.Sometimes a person has both problems. In both cases, the result is that glucose does not enter the cells and builds up in the blood.

In type 1 diabetes, the pancreas does not produce insulin, Without insulin, too much glucose stays in the blood and over time, high blood glucose levels can cause serious problems in the heart, eyes, kidneys, nerves, gums, and teeth.

With type 2 diabetes, the most common type, the body does not make or use insulin well. There is a higher risk of type 2 diabetes if the person is older, obese, have a family history of diabetes, or don't exercise. Also, having pre-diabetes also increases that risk because people who have pre-diabetes have higher than normal blood sugar but not enough to be considered diabetic.

So, in type 1 diabetes there is an absolute lack of insulin due to the destruction of the pancreatic islets. While type 2 diabetes is a metabolic disorder characterized by hyperglycemia (high blood sugar) in the context of insulin resistance.

What are two reactants needed to for cellular respiration

Answers

Answer:

oxygen and gluclose

Explanation:

Final answer:

The two essential reactants for cellular respiration are glucose, sourced from food, and oxygen, derived from the air. They combine in the process of cellular respiration to produce ATP (energy), carbon dioxide, and water.

Explanation:

The cellular respiration process in living organisms, primarily in eukaryotic cells such as plant and animal cells, requires two primary reactants: glucose and oxygen. Glucose (C6H12O6) is a simple carbohydrate that organisms derive from food, and oxygen (O2) is obtained from the air. During cellular respiration, these two reactants combine to produce energy in the form of ATP, alongside carbon dioxide and water as byproducts.
