Answer:

The most important are the lungs, more precisely the alveoli.

Explanation:

Alveoli are structures of the lungs where gas exchange occurs. They allow oxygen from the air to pass into blood. Oxygen diffuses through the walls of alveoli into the capillaries that surround it. Oxygen is then bonded with the iron in red blood cells and travels to the heart. The heart then sends the oxygenated blood out to all the cells in the body.

Use the following template strand of DNA and the coding table to determine the correct amino sequence and write this sequence be

REY [17]

DNA and RNA have the main difference in the presence of deoxyribose sugar in DNA and ribose sugar in RNA. One more is the presence of thymine in DNA while the presence of uracil in RNA.

<h3>What is the codon?</h3>

Codon is actually a three-letter code which is a sequence of three consecutive nucleotides in a DNA or RNA molecule which generally codes for a specific amino acid.

The DNA sequence given here is:

T A T A T C T A C G G T C C G G C A T C G A T T T C G

So the RNA sequence for this will be:

A U A U A G A U G C C A G G C C G U A G C U A A A G C.

So according to the table, the amino-acid sequence will be:

Isoleucine STOP Methionine Proline Glycine Arginine Serine STOP Serine.

Generally stop codon is responsible for the termination of protein synthesis.

Thus, this was the amino acid sequence for mRNA according to the given DNA sequence.

<span>He is at an increased risk for sudden infant death. Since he is sleeping on a mattress that might inhibit his breathing, as well as having respiratory issues that might do the same (along with parents who are smoking, which will only inhibit proper respiration further), he will need to be constantly checked to make sure he is sleeping properly.</span>

In men, the gene for baldness acts as a dominant gene and in women it acts as a recessive gene. A bald man who father was not ba

gogolik [260]

So: both parents' genotypes (concerning baldness gene) are the same: Bb. Possible genotypes of an offspring: BB, Bb, Bb, bb . bb means non-bald girl or boy. Bb means bald boy or non-bald girl. BB means bald boy or girl. there is 25% chance of conceiving a child with a genotype BB. But there is also 50% chance of conceiving a girl. So the answer is: 25% x 50% = 12,5%
