Explain why each chromosome must become two strands before the cell divides.​

Biology
1 answer:

Answer:

To allow transcription enzymes to access the DNA strand

Explanation:

The DNA double helix is made up of two complementary strands wound around each other, and tightly packaged as chromosomes.

DNA and RNA polymerases promote either DNA or RNA synthesis by attaching free nucleases to parent strands (a), which are then unwound and isolated by helicases (b). DNApolys synthesize DNA in a 5'-3 ' direction; owing to its restricted flow, there are only two types of replication: continuous from the point of differentiation of chromosomes, fork, and discontinuous from the fork.

Explain the main cause of degradation of our languages in belize? it's science but I put biology​
Nonamiya [84]

Language degradation is occurring because of the adoption of foreign languages.

<h3>How does this adoption take place?</h3>

The constant presence of foreign media and the adoption of foreign language terms is the main way to adopt a new language.

This adoption allows the local population to start mixing the two languages.

Over time this process becomes more intense, causing the local language to be replaced by a foreign language over time.

Language degradation is a process that occurs in many regions, but maintaining these languages is very important.
