1 answer:

In drosophila development, pattern development in the late embryo, larva, and adult is controlled by homeotic type of gene.

In Drosophila, development is controlled by homeotic type of gene. The beginning phases of development are controlled by homeotic genes. The general body plan of Drosophila is the same in the embryo, the larva, and the adult, each of which has a distinct head end and a distinct tail end, between which are repeating segmental units .

Three of these segments form the thorax, while another eight segments form the abdomen. Two different sets of genes control embryonic development in Drosophila maternal-effect genes and zygotic genes.

A scientist wants to begin making a DNA fingerprint, but she has only a very small DNA sample. What should her next step be

For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.

Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-

1. Denaturation of the double-stranded DNA (at around 95°C)

2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)

3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).

With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.

Neurons are brain cells. Where would a new neuron come from?

mihalych1998 [28]

Answer:

I think C

Explanation:

New neurons are born not from mature nerve cells but rather develop from neural stem cells that remain in our brains throughout life. Indeed, in some brain areas, there is continual turnover of neurons - old ones die and new ones are born - and these new neurons can participate in circuits that underlie learning.
