Answer:
C. keeping the strands separated during replication.
I think
Explanation:
The statements Molecule B can be used to produce molecule A and Molecules B and C interact so that amino acids can be joined together are TRUE regarding the structures shown in the diagram (Options B and E).
<h3>What are transcription and translation?</h3>
Transcription is the process by which a DNA template (molecule B) can be used to synthesize a complementary RNA (molecule A), while translation is a process in which an sequence is used as templates to generate a protein, which requires tRNAs (molecule C) to trasnport amino acids to the ribosomes.
Therefore, with this data, we can see that DNA is molecule B used to create RNA, which is molecule A, while tRNA is represented by molecule C and it is used during translation.

Answer:
3. An even number of chromosomes are required for synapsis during prophase I and proper pairing during metaphase
Explanation:
Mules are hybrids of a cross between a female horse and a male donkey. Horses contain 64 chromosomes while donkeys contain 63 chromosomes in their somatic cells respectively. This means that they each produce 32 and 31 chromosomes respectively during meiosis. A mule, hence, contains 32+31= 63 chromosomes in their somatic cells.
This chromosome number in mules are uneven for meiosis to occur because meiotic division requires that an even number of homologous chromosomes pair together in a process called SYNAPSIS during prophase I of meiosis I. This is impossible in a mule because of the uneven number of chromosomes in its cells.
Also, during metaphase of meiosis, the homologous chromosomes need to be properly aligned at the equator for separation to occur. This is also impossible in a mule considering the number of chromosomes that don't add up.
Due to this reason of unevenness in the number of chromosomes present in a mule, meiosis will not occur and if meiosis (gamete formation) does not occur, reproduction cannot take place. Therefore, the mule is a sterile species i.e. cannot produce offsprings via sexual reproduction.
