An elephant has 56 chromosomes. Which statement about a zygote of an elephant is true?

2 answers:

You divide the number of chromosomes in half, just like humans. So the female zygote has 28 chromosomes and the male sperm have 28 chromosomes. This way each set of chromosomes contributes the same amount to each sex cell.

The right answer is The zygote has 56 chromosomes, 28 inherited from the mother and 28 from the father.

In diploid organisms such as mammals, each individual has two copies of each gene, one from the mother and the other from the father (exception: sex chromosome genes). If these two versions are identical, the individual is said to be homozygous for the gene considered. In the opposite case, it has two different versions (two different alleles), and it is heterozygous for this gene.

If the sequence ATGCATGTCAATTGA were mutated such that a base were inserted after the first G and the third T were deleted, how

german

Answer:

Two

Explanation:

Consider the sequence ATGACATGCAATTGA.

Originally, there are 5 codons, translating to a minimum of 5 amino acids: ATG CAT GTC AAT TGA.

A base was inserted after the first G and the third T was deleted, the sequence become (assuming A is the inserted base);

ATG ACA TGC AAT TGA

Only the second and the the third codon are changed and hence, their respective amino acid.

Draw the structure of DNA nucleotide with adenine as nitrogenous base

zavuch27 [327]

Answer:

A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. Here is the structural formula for the four nucleotides of DNA. Note that the purine bases (adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.

Considering the nitrogen cycle, how do all organisms depend on bacteria to produce and maintain adequate nitrogen in the environ

emmasim [6.3K]

Answer:

Considering the nitrogen cycle, all organisms depend on bacteria to produce and maintain adequate nitrogen in the environment by eating the plants that contain bacteria which contain nitrogen.

Option: (B)

Explanation:

Nitrogen is a main element in the nucleic acid of both RNA and DNA which is most important for all living creatures and biological molecules.

When plants doesn’t get enough nitrogen it doesn’t produce amino acid, without amino acid plant cannot make special proteins.

Amino acid is building block for DNA which tends to the generation of organism.

Nitrogen fixation is a process where bacteria convert atmospheric nitrogen to usage form for plant and animals get nitrogen by eating those plants.
