Answer:
If my right leg is the cell wall and my left the membrane, do you want to be the cytoplasm?
Explanation:
<span>There is a remote possibility a barren rock could turn into a temperate forest, but this would have taken billions of years. It is not likely to have happened therefore I would have to say the answer is false.</span>
Answer:
Mendel's Laws are a set of basic rules on the inheritance of characteristics from parent organisms to their children. They are considered rules rather than laws, since they are not fulfilled in all cases. Mendel's first Law of equitable segregation establishes that during the formation of the gametes each allele of a pair is separated from the other member to determine the genetic constitution of the filial gamete, the two alleles, which code for each characteristic, are segregated during the production of gametes through meiotic cell division. This means that each gamete will contain only one allele for each gene. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation. For each characteristic, an organism inherits two alleles, one for each relative. This means that in somatic cells, one allele comes from the mother and one from the father.
Explanation:
Mendel's laws reflect chromosomal behavior during meiosis: the first law responds to the random migration of homologous chromosomes to opposite poles during anaphase I of meiosis (both alleles and homologous chromosomes segregate equally or 1: 1 in gametes) and the second law, to the random alignment of each pair of homologous chromosomes during metaphase I of meiosis (whereby different genes and different pairs of homologous chromosomes segregate independently).Even though not all genes are inherited in the proportions described by Mendel, they are undoubtedly all inherited in the same way, that is, the alleles or different alternatives of a gene are separated in meiosis and each gamete will carry only 1 of them (2nd Mendel's Law) and in turn all genes on different pairs of chromosomes are transmitted independently. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation.Therefore, of each possible genotype for a two three or more genotypes it is possible to know how many gametes it will form, in what proportions and therefore predict results of crosses.
- TGA (opal)
Answer:
Explained below
Explanation:
A mutation in a gene that results in total loss of the normal function of the gene product encoded by that gene, resulting in a Null phenotype.
Changes in DNA sequence are termed as nonsense mutation that introduce a stop codon, resulting in a non functional protein. This terminology results stop codons have also worked as nonsense codons.
There are three different stop codon-
In RNA
- UAG (amber)
- UAA (ochre)
- UGA (opal)
In DNA
- TAG (amber)
- TAA (ochre)
- TGA (opal)
