Every DNA strand has an EQUAL number of adenine and thymine nucleotides in a molecule. Explain why.

Biology
1 answer:
KATRIN_1 [288]3 years ago
6 0

Answer:

Explanation: In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs. This is the basis for Chargaff's rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine.

Forward chaining and backward chaining both involve:
dedylja [7]

Answer;

Forward chaining and backward chaining are Similar in that;

Both are used to teach a chain of behaviors.

Both use procedures,

Both teach one behavior at a time and chain the behaviors together.

Both procedures use prompting and fading to teach each component

Explanation;

-Backward chaining; When you teach the last stimulus-response component first. Then teach the next to last component and so on.

-Forward chaining; Teach the first stimulus-response component first. Then teach the second component and so on

The following relationships are known: CGG specifies Arginine, GGC specifies Glycine and GCG specifies Alanine. Based on your kn
shtirl [24]

Answer:

Arginine

Explanation:

A specific genetic code specifies a particular amino acid. One amino acid can be encoded by more than one genetic code.

When a particular amino acid is encoded by more than one genetic code, all the genetic code for that amino acid mostly share common first two bases and differ from each other in the last base. This allows the same tRNA with particular anticodon to read all the possible genetic code for that amino acid and to serve as a carrier due to wobble base pairing.

Given that code "CGG" specifies arginine, the code "CGA" should also specify "arginine" since both differ with respect to the last base only.

For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to
Reptile [31]

Answer: E. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.

Explanation:

The Hershey-Chase experiment, is an experiment that demonstrated that the genetic material of phage isn't protein but rather it's DNA.

Based on the information given in the question, the experiment will not work because amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.

Therefore, the correct option is E.
