If the sequence of one strand on DNA is CTA GCT CCA, what is the<br> complementary strand? *
vekshin1

Answer:

If the sequence of one strand on DNA is CTA GCT CCA,  the complementary strand is GAT CGA GGT.

Explanation:

The DNA molecule has four nitrogenous bases in its structure, two purines —adenine and guanine— and two pyrimidines, cytosine and thymine.

The two DNA strands are linked by hydrogen bonds established between their complementary nitrogenous bases, where a purine is complemented by a pyrimidine.

In the case of DNA, adenine is complemented by thymine and cytosine is complemented by guanine:

<em>A=T</em>

<em>C≡G</em>

In the sequence belonging to a DNA strand CTA GCT CCA, the strand that is complementary would be GAT CGA GGT.

KiRa [710]
A punnet square is used to visually see the dominant and recessive traits. Mendel's law says that alleles pair independently during the formation of gametes (aka sex cells). This means that traits are transmitted to offspring independently of one another.
