Answer:

BRCA1 and BRCA2 genes

Explanation:

The BRCA1 and BRCA2 genes are tumor suppressor genes that encode breast cancer susceptibility proteins involved in repairing double-strand DNA breaks (DSBs) by the mechanism of homologous recombination. This mechanism uses the sister chromatid of the homologous chromosome as template for repairing DSBs. It has been shown that mutations in BRCA1 and BRCA2 genes alter the molecular mechanism of homologous recombination DNA repair, thereby mutations are not repaired appropriately and persist in the DNA of tumor cells.

what is the resistance of a car light bulb that conducts 0.025 A current when connected to a 12 V car accumulator? Is the curren
tangare [24]

Answer:

R = 480 Ohm

Yes, the current is steady since the power supply is a constant 12V (comming from the battery).

Explanation:

U=I*R

R = U / I

U = 12 V

I = 0.025 A

R = 12 / 0.025

R = 480 Ohm

kobusy [5.1K]
The answer is plankton are floaters. Plankton and nekton are both marine aquatic organisms. The main difference between the two is that plankton tend to float and be carried by water currents while nekton are organisms that swim against the current of the water. Plankton are passive swimmers while neekton are active swimmers.

Which statement is true of crossing over?
Arada [10]

Answer:

B. It allows for genetic variation.

Explanation:

As prophase progresses, homologous chromosomes come to lie side by side and become intertwined rather like a zipper. This process is called synapsis. During synapsis, homologous chromosomes exchange genetic material between one another which allows for genetic variation. This exchange is called crossing over.
