The correct answer is B.

According to base pairing rules, A will always pair with T and and G will always pair with C. This pairing happens in DNA.

When it comes to RNA, there is a slight difference. Thymine is never found in RNA but is replaced with Uracil. So instead of Adenine pairing with Thymine, it will be Uracil which takes the place of Thymine.

It is important to note that Thymine in DNA will code for Adenine in RNA because Adenine is found in RNA base sequence. However whenever Adenine in DNA wants to code for a complementary base to copy on <span />RNA, then Adenine will call for Uracil, not Thymine.

Match the genetic mutations with their names.

dusya [7]

Answer:

1. CGAGGTT → CGTT (Deletion)

2. ATTCGG → ATTCGGATTCGG (Duplication)

3. CTTAAT → TAATTC (Inversion)

4. CTTAAT → CTTAACGCT (Insertion)

5. CGAT → CTAT (Substitution)

6. CCGGTT + TTAGGC = CCGTTA + GTTGGC (Translocation)

Explanation:

1. CGAGGTT → CGTT (Deletion) ---- This is called deletion because it involves the removal of 3 base pairs (AGG) from the DNA sequence.

2. ATTCGG → ATTCGGATTCGG (Duplication) ---- In this case, the particular sequence (ATTCGG) is copied again or duplicated.

3. CTTAAT → TAATTC (Inversion)----- This is called inversion mutation because the DNA sequence breaks off and is reattached but this time in a reverse order i.e. CTT becomes TTC, placing the last base first and the first base last.

4. CTTAAT → CTTAACGCT (Insertion) ------ This is called insertion mutation because it involves the addition of extra base pairs (CGC) into the sequence. The Insertion occurs between the last A and T nucleotide.

5. CGAT → CTAT (Substitution) ----- This is called substitution because Guanine base is replaced by Thymine in the DNA sequence. It is specifically called a transversion substitution because a purine (Guanine) is replaced by a pyrimidine (Thymine). It is called a point mutation because it involves a single base.

6. CCGGTT + TTAGGC = CCGTTA + GTTGGC (Translocation) ----- in this case, CCGGTT and TTAGGC are sequences on different chromosomes. Portions of sequence on the first chromosome (GTT) and second chromosome (TTA) breaks off and gets reattached/exchanged in each other i.e. the first chromosome gets TTA while the second gets GTT. This kind of mutation is called translocation.

seropon [69]

Answer:

the balance is everything must have a process of living and dying in an ecosystem. such as, an animal killing another animal for prey to eat it, that is a process. in a water ecosystem, fish lay eggs and come out and usually get eaten by a bigger animal, as they grow up, usually by bigger fish itself such as the Grayling.
