Answer:
A gamete containing an extra chromosome is formed.
Explanation:
Geminal mutations may result in the production of mutant gametes. If such gametes fuse with those from another individual of the opposite sex to form a zygote, the mutation is transmitted to the progeny. A trisomy gamete containing an extra chromosome would transmit the mutation to the offspring after fertilization.
Answer:
The statement suggests ability of existing DNA molecule to replicate itself by the process of DNA replication. Each strand of double helical DNA can serve as template for the synthesis of new complementary DNA strand.
Explanation:
Watson and Crick proposed the double-helical structure of DNA. Accordingly, the DNA molecule is a double helical structure in which two polynucleotide chains are held together by base pairing between the complementary bases of two chains.
There are four nitrogenous bases present in DNA: adenine and guanine (purines) and cytosine and thymine (pyrimidines). Adenine always pairs with thymine and cytosine pairs with guanine base.
According to Watson and Crick, the ability of one DNA strand to base-pair with a complementary DNA strand suggests the existence of the DNA replication process. During DNA replication, each DNA strand should serve as a template to specify the nucleotide sequence of the new DNA strand.
Answer:
Viruses exhibit two out of above mentioned which are
1. They contain genetic information
2. They reproduce
Explanation:
Viruses can be classified as either living or non living organisms
They can be classified as living organisms because of the following reasons
1. They can mutate
2. They can grow
3. They evolve to adapt to their hosts
4. They are capable of multiplication in their host cells
5. They are made up of proteins and glycoproteins like cells do
6. They have genetic information which helps them to produce more viruses in the form of either RNA or DNA.
They can also be classified as non living organisms because
1. They can not exist outside their host cell
2. They do not carry out metabolism, they make use of their host mechanisms

c = g
t = a
Just switch the letter around to find the opposite of your given strand.
