What might be an advantage of having more than one codon for the same amino acid?

1 answer:

8 0

The extra codons mean the code is more resilient- small errors can still result in the same protein being produced. The other advantage is that in some cases, a single strand of genetic material might code for more than one protein or enzyme, depending on how it is read. This means that one method of reading will produce the same output, but the second or third method of reading (starting from a different place on the strand) can produce other, entirely different materials. This concept is like a palimpsest.

How many grams are NaCl are required to prepare 200 mL of a 3.10 M solution?

rodikova [14]

The mass (in grams) of NaCl required to prepare the solution is 36.27 g

<h3>What is molarity?</h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the mole of NaCl</h3>

Volume = 200 mL = 200 / 1000 = 0.2 L
Molarity = 3.1 M
Mole of NaCl =?

The mole of NaCl in the solution can be obtained as follow:

Molarity = mole / Volume

Cross multiply

Mole = Molarity x Volume

Mole of NaCl = 3.1 × 0.2

Mole of NaCl = 0.62 mole

<h3>How to determine the mass of NaCl </h3>

We can obtain the mass of NaCl needed to prepare the solution as follow:

Molar mass of NaCl = 58.5 g/mol
Mole of NaCl = 0.62 mole
Mass of NaCl = ?

Mole = mass / molar mass

Cross multiply

Mass = mole × molar mass

Mass of NaCl = 0.62 × 58.5

Mass of NaCl = 36.27 g

On the lines provided, enter the name of the target organ(s) affected by the pituitary hormone indicated. Hypothalamic nerve cal

Dennis_Churaev [7]

Produced by the anterior pituitary. It's regarded as a tropical hormone. Target cells are impacted by tropical hormones indirectly after being stimulated.

<h3>The anterior pituitary gland affects which organs?</h3>

The following organs, glands, and bodily tissues are affected by and interact with the anterior pituitary hormones: organs, muscles, and bones the growth hormone (GH). Adrenocorticotropic hormone: Adrenal gland (ACTH). thyroid hormone, which stimulates the thyroid gland (TSH).

<h3>What are the anterior pituitary gland's seven hormones?</h3>

Frontal pituitary

hormone adrenocorticotrophic (ACTH)

hormone that stimulates the thyroid (TSH)

Luteinizing agent (LH)

hormone that stimulates ovulation (FSH)

Prolactin (PRL) (PRL)

hormonal growth (GH)

MSH, or melanocytic-stimulating hormone

Because it releases hormones that regulate the thyroid, adrenal glands, ovaries, and testes, the pituitary gland is frequently referred to as the "master gland."

What happens if there are no checkpoints in the cell cycle.

Slav-nsk [51]

Answer:

they may "loop out" of the cell cycle and into a resting state called G0, from which they may subsequently re-enter G1 under the appropriate conditions

Explanation:

At the G1 checkpoint, cells decide whether or not to proceed with division based on factors such as: Cell size

Imagine that you discover three different bacterial species on a meteorite. Each species contains genetic material that is not D

jeka94

Answer:

Species A: 2

Species B: 56

Species C: 162

Explanation:

Codons are sequence of 3 purine or pyrimidine bases that codes for amino acids. Each codon in mRNA eventually binds with anticodon in tRNA during protein synthesis and gets translated into their respective amino acids. Hence, the number of amino acids in each of the species represents the minimum number of codons in each species.

<em>Therefore, species A with 2 amino acids will have a minimum codon length of 2, species B with 56 amino acids will have minimum of 56 codons while species C with 162 amino acids will have minimum codon length of 162.</em>
