Which recent discovery led to a new understanding of how genetic mutations increase the risk of cancer? double helix structure of DNA BRCA1 and BRCA2 genes nucleic acid monomers formation of tumor suppressor proteins

Answers

Answer 1

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.

Answer 2

(B.) BRCA1 and BRCA2 genes

Sarah and Thomas are thinking about having kids. They are concerned that because Thomas’s father was diagnosed with cystic fibrosis last year, it could run in the family. Cystic fibrosis is a recessive genetic disorder which affects the respiratory system. Both Thomas and Sarah get tested for the recessive allele (f), with the results indicating that they are each carriers of the disorder (a genotype of Ff).
Is it possible for Sarah and Thomas to develop cystic fibrosis?

Answers

No they can not develop it because they are carriers and do not have ff only Ff, but their kids have a high chance of getting it. (50% chance)

I WILL GIVE BRAINLIEST TO THE WHOEVER HELPS ME

Answers

Answer:

Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues. In adults most cell division is involved in tissue renewal rather than growth, many types of cells undergoing continuous replacement.

Explanation:

Internal monitors called checkpoints track each step of the cell cycle. In the cell cycle, there are three main checkpoints; one at the end of G1, a second at the transition of G2/M, and a third during the metaphase. Positive molecules of the regulator allow the cell cycle to proceed to the next level.

Mitosis, although continuous process, is conventionally divided into five stages: prophase, prophase, metaphase, anaphase and telophase.

Which type of reproduction is responsible for genetic variation?

Answers

Answer:

sexual reproduction

Explanation:

Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.

Other reproductions like asexual, budding or fragmentation don't produce genetic variation.

The type of reproduction is responsible for genetic variation is - sexual reproduction.

Sexual reproduction is combining genetic information from two individuals,  by the fusion of gametes such as sperm and egg, called fertilization which generates more genetic variation, by the process like the combination of alleles and crossing over.

Parents and offsprings are not identical in this reproduction type, however, they are genetically similar.Fusion or combination of two different parent's gametes.There is recombination take place which causes genetic variations as well.

Thus, the correct answer that is responsible for genetic variation is - sexual reproduction.

if the egg of a particular butterfly has 14 chromosomes, how many chromosomes will be found in a somatic cell for this butterfly - PLEASE HELP DUE TONIGHT ​

Answers

Answer:

not

Explanation:

If the egg of a particular butterfly has 14 chromosome, then the somatic cells will have same 14 chromosomes.

What are somatic cells?

A somatic cell, also known as a vegetal cell, is any biological cell other than a gamete, germ cell, gametocyte, or undifferentiated stem cell that forms the body of a multicellular organism.

These cells make up the body of an organism and divide via binary fission and mitotic division.

Mitosis is a cell division process that produces somatic cells. They have two copies of each chromosome, one from the mother and one from the father. Diploid cells usually have two copies each of each chromosome.

Mitosis is the method by which one cell splits into two genetically identical daughter cells.

The cell's chromosomes are copied and then distributed evenly between the two new nuclei of the daughter cells during the various stages of mitosis.

Thus, as these are somatic cells, they will have same number of chromosomes.
