Biology
1 answer:
pav-90 [236]4 years ago
4 0

A PCR is used to amplify DNA. The heating breaks the hydrogen bonds and ensures that the double-stranded DNA helix is melted such that the two strand separate. The cooling ensures that the introduced DNA primers bind with the single strands so that elongation of the chain (to form a new double helix) can be possible by DNA polymerase.

andreev551 [17]

Answer:

Explained below:

Explanation:

The interactions of the homologous chromosomes are the cause of two siblings who will never look exactly the same but in the case of twins only. And if we talk about mitosis, in mitosis, all the chromosomes will be folded themselves, while the homologous chromosomes will not surely line up and share genetic reshuffling. This is also known as crossing-over. This can happen between various chromosomes or different sections of the same chromosome.

A cell needs more of Protein X to function. Describe every way it is possible to INCREASE that protein. I don’t understand this
Natasha_Volkova [10]

It is possible to INCREASE the levels of the protein X by transcription factor binding and epigenetic modifications that induce the expression of the protein-coding gene.

<h3>What are transcription factors?</h3>

Transcription factors can be defined as specific proteins that bind to certain gene regions called promotors in order to promote the transcription of genes.

Moreover, epigenetic modifications such as DNA methylation and histone acetylation may alter the structure of chromatin in order to enable gene transcription.

In conclusion, it is possible to INCREASE the levels of the protein X by transcription factor binding and epigenetic modifications that induce the expression of the protein-coding gene.
