Answer:
3. haploid; diploid
Explanation:
Sperm is male gamete or often called male reproductive cell. During the process of spermatogenesis, reductional division (meiosis) occurs in the spermatocytes and spermatids are formed which further mature to sperms. Thus as a result of meiosis, their chromosome number is reduced to half and thus they become haploid cells. During oogensis, eggs are also formed as a result of meiosis which reduces the chromosome number and so eggs are also haploid.
When during fertilization, these two haploid nucleus of these cells fuse together, they form a diploid zygote.
Answer:
1. It could result in a loss of function of the protein product
2. It could result in a protein product with excessive activity
3. It could result in altered structure of the protein
Explanation:
Any changes that occur in the nucleotide sequence in the DNA of an organism is known as a mutation. Various forms of mutation can occur in the DNA sequence of an organism which could be as a result of insertion or deletion of a nucleotide in the DNA sequence.
Insertion of an extra nucleotide into a DNA strand within a gene could have any of the following effects on the protein protein;
1. It could result in a loss of function of the protein product of the gene whereby the protein can no longer carry out its normal functions
2. It could result in a protein product with excessive activity other the normal range at which it functions.
3. It could result in altered structure of the protein either in the primary, secondary, tertiary, or quaternary structure
