Answer:
mRNA: 3' AUG-AAU-GCU-GCC-GGU-GA-5'
amino acids : methionine, asparagine, alanine, arginine, proline
type of mutation: deletion, missense
Explanation:
The mRNA sequence is complementary to the DNA sequence. A always pairs with T, C always pairs with G. Except this is an RNA sequence not a DNA sequence, so T is replaced with U.
The mRNA sequence is translated into an amino acid sequence based on the triplet code. The triplet code for this sequence is shown in the attached picture. Each triplet signifies a specific amino acid. The codon can be identified from the table and placed in sequence. We can see that the new DNA strand has caused a new amino acid sequence. It has also left us with an incomplete sequence, as GA cannot signify an amino acid.
The type of mutation is a single base deletion. We can see that the base C is missing from the 9th amino acid in the original strand. As you can see, this has an ongoing affect on all the bases in the rest of the sequence, as it changes the way the sequence is organised into codons. This results in a missense mutation.
Answer:
C. When running that is the answer
Answer:
List of options to choose from to complete the question:
A. Aneuploidy
B. Polyploidy
C. Translocation
D. Monosomy
E. Duplication
The CORRECT ANSWER IS A.
A. Aneuploidy.
Explanation:
Aneuploidy results from unusual number of chromosomes in a cell, e.g a human cell with 45 or 47 chromosomes other than 46.
It's mostly seen in Trisomy e.g. trisomy 21 (Down syndrome), trisomy 13 (Patau syndrome) and trisomy 18 (Edwards syndrome).
Answer:
Haploid number of chromosomes.
Explanation:
Before fusion of sex cells i. e. sperm cells and egg cells, there are half number of chromosome present in each sec cell because in the sex cells meiosis occurs. Meiosis is a type of cell division in which a single parent cell divides into four daughter cells having haploid chromosome i. e. half number of chromosomes in each daughter cell. So when these sex cells fuse together, they form a diploid organism.
