Answer:
Original reading frame=> (ATG)(CGT)(CCA)(TGA)
Altered reading frame => (ATG)(CAC)(GTC)(CAT)(GAG)
Explanation: A frame shift mutation is a type of mutation in which there is addition or deletion of one or more nucleotides in a DNA sequence which results in alterations in the original reading frame of the DNA sequence. In the altered reading frame above two nucleotides were added at positions 4 and 5 thereby changing the subsequent reading frame of the DNA. Frame shift mutation can result in permanent change in DNA sequence during replication and subsequently in altered RNA sequence during transcription and altered amino acid sequence of the final gene product.
Answer:
a) Ribosomes
Explanation:
Ribosomes are organelles that initiate protein synthesis in cells. Both Eukaryotes and prokaryotes encompass ribosomes with them. However, They are structurally different in Eukaryotes and prokaryotes such as Bacterial Cells.
Answer:
Option B,
Explanation:
Proper restraint and handling techniques are used while dealing with animals in laboratory. These techniques ease the process of dealing with animals and must be practiced on regular basis even when there is no procedure being performed.
Unlike other animals cat is the most co-operative animals and it is usually dealt by restraining the body be one hand and head by other hand. Cats can also be restrained by holding the scruff with one hand and then gently holding the hind limbs followed by stretching it.
Hence, option B is correct.
Answer:
A
Explanation:
Increase enzyme concentration so more enzymes can react with carbon dioxide to form bicarbonate. D would make the reaction slower, C does not relate to the question and B is the product so would not help increase the rate of the reaction, only A
The answer is horizontal gene transfer.
Horizontal gene transfer enables gene flow between genomes of two organisms. It is a common process between different species of <span>prokaryotes and even, between prokaryotes and eukaryotes. </span>When trying to reconstruct evolution and phylogenetic relationship, scientists face some difficulties because they cannot say the common gene transfer with the horizontal one.
