Sequence of m-rna that is not involved in coding for a protein which is cut out before it is read by the ribosomes
Doss [256]
The correct answer is introns.

Introns are non-coding sequences in the immature mRNA made from DNA transcription. Since they are non-coding, they do not contribute to the final protein that will be translated; therefore introns need to be removed. Introns are removed by RNA splicing; and this is succeeded by 5' capping and adding of poly-A tail.

10. If one strand of DNA is
soldi70 [24.7K]

Answer:

Explanation:As previously stated, DNA is a macromolecule that's made up of individual subunits called nucleotides. Each nucleotide has three parts:

Brought to you by Sciencing

A deoxyribose sugar.

A phosphate group.

A nitrogenous base.

DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C).

These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.

The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.

Complementary Definition (Biology)

In biology, specifically in terms of genetics and DNA, complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement, or the pair, of the other strand.

If each parent is brown-eyed with a recessive blue-eyed gene, what is the probability of having a brown-eyed child? A blue-eyed
Alexxx [7]
Brown eyes + blue eyes = 50% chance of blue eyes, but only if the brown-eyed parent carries a blue-eyed gene. If not, the chance is 0% Brown eyes + brown eyes = 25%, but only if both parents carry the blue-eyed gene.

a 25% If both of you have brown eyes, then there is generally a 25% chance that the baby will have blue eyes if both of you carry the recessive blue-eye gene. But if only one of you has a recessive blue-eye gene, and the other has two brown, dominant genes, then there is a less than 1% chance of the baby having blue eyes.
