One strand of a DNA molecule has the base sequence ATAGGT. The complementary base sequence on the other strand of DNA will be ________.

CGCUUC
CGCTTC
UAUCCA
TATCCA

Sagot :

Answer:  Choice D)  TATCCA

==============================================================

Explanation:

In DNA, there are four basic building blocks

  1. Adenine
  2. Thymine
  3. Guanine
  4. Cytosine

We can abbreviate them to A, T, G, and C in that order.

The order I mentioned is often what biology and chemistry textbooks go with because A pairs with T as a complementary base pair, and G pairs with C.

So if one strand has A, then directly across from it will be T, and vice versa. Refer to the diagram below. The image is not mine and something I searched for after typing in "DNA diagram".

------------

Now to the problem at hand. We're given that one strand has the sequence ATAGGT

Since A is listed first, directly opposite this must be T which is on the other strand.

So T is the first letter in the answer. Choice D is the only one that fits, which is why it's the final answer.

If one strand of a DNA molecule has the base sequence ATAGGT, then the complementary base sequence on the other strand of DNA will be TATCCA.

DNA is a double helix molecule composed of two long chains of nucleotides. The complementary nucleotides in opposite DNA strands are paired together by hydrogen bonds.

In DNA, there are four types of nucleotides, each one containing a different nitrogenous base (i.e., Adenine, Guanine; Cytosine and Thymine).

According to the base pair rules, Adenine always pairs with Thymine by two hydrogen bonds, whereas Guanine pairs with Cytosine by three hydrogen bonds.

In conclusion, if one strand of a DNA molecule has the base sequence ATAGGT, then the complementary base sequence on the other strand of DNA will be TATCCA.
