A cell with 80 chromosomes undergoes meiosis. How many chromosomes are found in the daughter cells? How many daughter cells are
qwelly [4]

Answer:

Four daughter cells are produced each with 40 chromosomes. The daughter cells would exhibit genetic variations and would not be genetically identical to each other.

Explanation:

Meiosis is a cell division that forms four daughter cells from one parent cell as two sequential division meiosis I and meiosis II do not include any DNA replication between them. Crossing over during prophase-I of meiosis-I includes the exchange of genetic segments and occurs between the homologous chromosomes. It produces new gene combinations in the daughter cells which were otherwise not present in the parent cell.

Since there is no DNA replication between meiosis I and meiosis II, the daughter cells have half the number of the chromosomes compared to the parent cell. This occurs as homologous chromosomes move towards the opposite pole during anaphase I.

Therefore, a parent cell with 80 chromosomes will make a total of 4 daughter cells by meiosis. Each daughter cell would have 40 chromosomes. These daughter cells would have some new gene combinations and would be genetically dissimilar among themselves.

if a parent cell starts with 22 chromosomes how many chromosomes will each daughter cell have after mitosis
salantis [7]

Answer:

For mitosis, the DNA content of the daughter cells and the mother cell will always be identical. Since the number of cells have doubled, so has the DNA. The 16 chromosomes in the mother cell will be duplicated, then the duplicates split and evenly divided into the daughter cells. The 16 chromosomes in each daughter cell will be non-duplicated at first.

The template strand of part of a gene has the base sequence TGAGAAGACCAGGGTTGT. What is the sequence of RNA transcribed from thi
Klio2033 [76]

Answer:

The answer to your question is ACUCTTCUGGUCCCAACA

Explanation:

Base sequence

                         TGAGAAGACCAGGGTTGT

Nitrogenous bases change from DNA to RNA

                   DNA                      RNA

                      Adenine                 Uracil

                      Thymine                  Adenine

                      Guanine                 Cytosine

                      Cytosine                 Guanine

Then from left to right, the new sequence the RNA is

                       

                           ACUCTTCUGGUCCCAACA
